A head mount temperature transmitter is crucial in industrial control instrumentation, particularly in processes where precise temperature measurement and control are essential. The transmitter is mounted directly on or near the temperature sensor in the sensor housing, in the protective enclosure known as a "connection head" or "thermowell head." The transmitter fits into or onto this head, making it a part of the sensor assembly. Here's a detailed description of its functionality and value:

Functionality

• Temperature Sensing: The primary function of a head mount temperature transmitter is to sense temperature and connect with a temperature sensor, such as a thermocouple or a Resistance Temperature Detector (RTD).
• Signal Conversion: The transmitter converts the raw signal from the sensor into a standardized signal, usually a 4-20 mA current signal, although it can also be a digital signal like HART, Foundation Fieldbus, or PROFIBUS.
• Signal Isolation and Amplification: These transmitters isolate and amplify the signal for more accurate and reliable readings, essential in industrial environments where electrical noise or long transmission distances could affect signal integrity.
•  Local Mounting: As the name suggests, head mount transmitters are mounted directly on or near the sensor, typically in the connection head of the temperature sensor. This proximity minimizes signal degradation that can occur over long distances.

Value in Industrial Applications

• Accuracy and Stability: By converting the signal close to the sensor, head mount transmitters reduce potential errors and losses in signal transmission, leading to more accurate and stable measurements.
• Reduced Wiring Costs: Wiring requirements are simple, reducing installation and maintenance costs because of the standardized signal.
• Improved Noise Immunity: Proximity minimizes the impact of electrical noise, which is especially valuable in industrial environments with high electromagnetic interference.
• Ease of Integration: Standardized output signals make integrating these transmitters into a wide range of control and data acquisition systems easier.
• Environmental Protection: Many head mount transmitters come with robust, weatherproof enclosures, making them suitable for harsh industrial environments.
• Flexibility and Scalability: They offer flexibility regarding sensor types and signal outputs, making them adaptable to various applications and scalable for future expansions or modifications in the process control system.

In summary, head-mount temperature transmitters play a pivotal role in industrial control systems by enhancing temperature measurements' accuracy, reliability, and efficiency.

Industrial Open Air Radar Transmitters Powered by FMCW Technology

Basic Understanding of Radar

Radar (Radio Detection and Ranging) is a system that uses electromagnetic waves to identify the range, altitude, direction, or speed of both moving and fixed objects such as aircraft, ships, motor vehicles, weather formations, and terrain. It transmits a signal, bouncing off the target and returning to the radar system. By analyzing the reflected signal, the radar can determine various parameters about the target.

FMCW (Frequency Modulated Continuous Wave)

When discussing FMCW, we are talking about a specific type of radar signal. Here's how FMCW works:

1. Continuous Wave (CW): Traditional radar systems emit a brief pulse of radio energy and then wait for that pulse to reflect off an object and return. In contrast, Continuous Wave radar emits a constant signal or wave.
2. Frequency Modulation (FM): In FMCW radar, the frequency of the continuous wave signal is varied or modulated over time. This can be done linearly, where the frequency increases or decreases at a constant rate or in other patterns.

The benefit of FMCW is that the frequency change provides a way to determine the range (distance to an object). There's a delay when the transmitted wave bounces off an object and returns. During this time, the transmitted wave's frequency has changed. By comparing the received wave's frequency to the current transmitted frequency, the radar system can determine how long it took for the wave to return and thus calculate the distance to the object.

FMCW radar is handy because it can be more compact, requires less peak transmit power (because it's continuous wave and not pulsed), and can provide range and speed information simultaneously.

Open Air Radar Transmitters

"Open air" in the context of radar transmitters usually refers to systems that operate without waveguides or enclosed transmission mediums. Instead, they transmit their signals directly into the environment. These systems are used in various applications, including vehicle radars (like those used in adaptive cruise control or autonomous vehicles), weather radars, and more.

Summary:

An open-air radar transmitter that uses FMCW is a radar system that transmits a continuous wave signal directly into the environment, modulating the signal's frequency over time. By analyzing the frequency shift of the returned signal relative to the transmitted signal, the radar can determine the range to the reflecting object. This technology is widely utilized due to its efficiency, compactness, and ability to provide detailed information about detected objects.

Drexelbrook's open-air radar products deliver exceptional resolution and accuracy tailored for demanding applications. These instruments harness FMCW (Frequency Modulated Continuous Wave) technology, ensuring a powerful signal at the measurement surface. This robustness guarantees optimal return signals, even when measuring agitated liquids.

A Drexelbrook radar level transmitter stands out as the optimal choice for applications that necessitate non-contact technology.

Advanced Water Level Monitoring in Sewage Pools

The complex sewage system of a power plant necessitates immediate maintenance and management. The water utilized for operating turbines and other waste materials runs through the sewage system, and ultimately to the municipal wastewater treatment facility.

Some treatment pools are located in isolated areas around the plant, making it challenging for maintenance staff to access and repair damage promptly. Plant maintenance personnel continually look for ways to more effectively manage the pools and avoid situations where wastewater could overflow.

With the sewage system linked to a central control room, data from each sewage pool has to be transmitted to the primary Distributed Control System (DCS). To achieve optimal management of the sewers, continuous monitoring and attendants are usually necessary.

Technicians understand that sewer blockages inevitably lead to wastewater flooding due to the time required for the equipment to address the backup. This flooding results in significant damage to the surrounding area. Hence, it is crucial to regulate the wastewater level in the pools to prevent such incidents from occurring.

An outstanding solution for this problem is to install two Drexelbrook USonic continuous level transmitters to monitor level in the sewage pools. The USonic's capability to deliver contactless, continuous, and precise water level readings in the pools provide engineers with a comprehensive understanding of the pools' condition. The device's compact size and integral design facilitate easy installation, enabling a quick and efficient solution. With a measuring range of up to 30 feet, the USonic effortlessly provides water level readings of the 12-foot-high sewage pools. Its scan distance function can identify obstacles in the pool and record interfering signals. The USonic connects to the central control system via a 4-20mA interface, granting the engineers constant oversight of the water levels in the sewers, ensuring that the sewers would maintain the appropriate water level and the system would receive a notification in the event of an emergency.

Elastomer-Lined vs High-Performance Butterfly Valves: Which One Suits Your Needs?

Butterfly valves, a type of quarter-turn valve, see widespread use in controlling the flow of various fluids in industrial settings. Their simple structure features a disc in the center of the pipe with a rod passing through it, connecting to an external actuator. When the actuator rotates, it turns the disc parallel or perpendicular to the flow. Butterfly valves simplicity, compactness, and relatively low cost contribute to their popularity.

Butterfly valves fall into two main categories: elastomer-lined (or rubber-lined) and high-performance butterfly valves (HPBVs).

Elastomer-Lined Butterfly Valves: This type represents the most common butterfly valves, frequently used in low-pressure and temperature applications. Their design incorporates an offset disc, meaning it doesn't sit centrally within the valve body. This disc rotates 90 degrees from the open to the closed position, and the valve typically includes an elastomer (rubber) liner that forms a seal when the valve is closed. Several advantages come with the rubber liner. It provides a tight seal and shields the body from the medium under control. 

These valves prove suitable for handling mildly corrosive fluids or those with minor solid content. However, the rubber liner may degrade over time or with exposure to harsh substances or temperatures, limiting its applicability under certain conditions. 

Common applications include: 

• Water Treatment Plants: In water treatment plants, operators often use these valves to throttle service, control flow rate, or as on-off valves.
• Chemical Industry: These valves frequently appear in the chemical industry, where they handle mildly corrosive substances or fluids with small amounts of solid content. They control the flow of various chemical products in pipelines.
• HVAC Systems: Heating, ventilation, and air conditioning (HVAC) systems employ these valves to regulate the flow of chilled or heated water.
• Food & Beverage Industry: The food and beverage industry uses these valves to maintain sanitary conditions, thanks to their ability to handle gentle cleaning and sterilization procedures.

High-Performance Butterfly Valves (HPBV): The design of HPBVs is more sophisticated than standard elastomer-lined butterfly valves. These find use in higher pressure and temperature applications, where a regular rubber-lined valve wouldn't suffice. Typically, they follow a double-eccentric or triple-eccentric design, where the stem sits away from the centerline of the disc, and the disc's centerline also deviates from the bore's centerline. This arrangement reduces wear and enhances sealing capabilities. In terms of sealing, these valves use a metal seat and a seal typically made from a softer, high-temperature-tolerant material instead of an elastomer liner. This design provides a tighter seal and allows them to handle higher pressures and temperatures compared to elastomer-lined butterfly valves. They last longer due to their metal seat design. Despite their advantages, HPBVs come with some drawbacks. Their complex structure and the materials used make them generally more expensive. They also come larger and heavier, necessitating more space and support. 

Common applications include:

• Oil & Gas Industry: The oil and gas industry widely uses high-performance butterfly valves due to their ability to withstand higher pressures and temperatures. They control the flow of oil or gas in pipelines and processing equipment.
• Power Generation: Power plants use them, especially in steam and feed water lines, where high temperatures and pressures are typical.
• Chemical Plants: Chemical plants also use these valves to handle aggressive chemicals at higher temperatures and pressures.

In summary, the choice between elastomer-lined and high-performance butterfly valves hinges on application specifics, including the pressure and temperature conditions, the type of fluid under control, and the desired lifespan and reliability of the valve.

Plugged Chute Detection Technology: The Superiority of RF Admittance

The operation of industrial processes is a delicate balance of efficiency, safety, and maintenance. A crucial part of maintaining this balance is ensuring the smooth operation of material handling systems, which often employ chutes to transport bulk materials. One common complication these systems face is the problem of chute blockages or plugging, a critical issue that can lead to costly downtime, equipment damage, and potential safety hazards.

Plugged chute detection technologies mitigate these challenges, offering early detection and warning of chute blockages. However, the effectiveness of these technologies varies, and understanding their characteristics is essential for making an informed decision.

Overview of Plugged Chute Detection Technologies

Plugged chute detection technologies fall into three broadly classified groups, mechanical, acoustic, and electromagnetic methods.

Mechanical systems, such as tilt switches and paddle wheel indicators, are simple and inexpensive but prone to mechanical failure and false alarms due to vibration or material buildup. They also require regular maintenance to function effectively.

Acoustic detectors, on the other hand, utilize microphones to listen for changes in the acoustic signature of material flow. While this can be an effective method, it is sensitive to environmental noise and requires sophisticated signal processing to distinguish between normal and blocked flow.

Electromagnetic methods include capacitive probes, microwave radar, and RF Admittance. These offer non-contact detection and are less prone to false alarms and mechanical failures—however, the material's properties, environmental conditions, and installation setup affect their performance and application.

RF Admittance: The Optimal Choice

After an extensive review of these technologies, RF Admittance emerges as the overall best selection for plugged chute detection for several reasons:

Reliability

RF Admittance technology uses a probe to measure changes in the dielectric constant (a property of materials that affects their response to an electric field) between the sensor and the chute wall. When the chute is clear, the admittance (the measure of how easily a circuit or device allows an electric current to pass) between the probe and chute wall will be at one level, and when the chute is blocked, the admittance will change significantly. This reliable detection method leads to fewer false alarms than mechanical and acoustic systems.

Resistance to Material Buildup

One of the significant advantages of RF Admittance technology is its resistance to material buildup on the probe. The technology uses a driven shield construction that ensures only the material near the active sensor affects the reading. This feature helps to eliminate the risk of false alarms due to material buildup, a common issue in other technologies.

Versatility

RF Admittance technology works with various materials, regardless of their conductive or non-conductive properties, making it a versatile solution in different industries handling multiple types of bulk materials.

The Drexelbrook Solution

The Drexelbrook Plugged Chute Detector consistently identifies whether material is flowing through chutes. If the material ceases to flow due to a blockage, an alarm from the flush-mounted capacitance sensing element will be triggered, prompting further necessary actions such as notifying an operator or shutting down a conveyor belt.

The Drexelbrook detector, also known as a blocked chute switch, reliably tracks the presence or absence of bulk solids material in chutes without compromising flow speed. This cost-effective device ensures the continuous flow of materials.

Its robust sensor design makes this point-level switch optimal for handling materials such as coal, wood chips, ores, and powders. Since it is flush mounted through a chute wall, there is no protrusion into the chute to hinder or obstruct material flow.

The point-level switch can automatically identify and disregard coatings, thus preventing false alarms. It features a universal power supply that auto-detects and adjusts to the input power source.

Unlike similar technologies, the point-level switch for detecting plugged chutes permits remote electronics installation at a convenient or safer location.

The dependable detection of plugged chutes ensures smooth plant operations and significantly reduces the chance of spills due to blockages.

Key Features:

• Availability of both curved and flat sensors
• DPDT relay dry contacts rated at 5A, 120VAC
• Requires less maintenance compared to other technologies; devoid of any moving parts that could potentially hang up or wear out
• Utilizes Drexelbrook PML series electronics
• Auto-detecting supply voltage range: 19-250 VAC, 18-200 VDC, without the need for jumpers
