Industrial Open Air Radar Transmitters Powered by FMCW Technology

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

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.

Plugged Chute Detection Technology: The Superiority of RF Admittance

The Best 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

The Role of Metal Expansion Joints

Metal Expansion Joints

Expansion joints, also known as bellows or compensators, are flexible connectors that are used in process and HVAC piping systems to absorb movements, such as thermal expansion and contraction, vibration, and misalignment. They are designed to prevent damage to the piping system, equipment, and surrounding structures by allowing for the movement and stress that occurs within the system.

There are several types of expansion joints, including metallic, non-metallic, and fabric. Metallic expansion joints are made of metal bellows and are typically used in high-pressure and high-temperature applications, as well as in applications that require a high degree of corrosion resistance. These expansion joints are typically made of stainless steel, but they can also be made of other metals such as Inconel, Monel, and Hastelloy.

The main function of metallic expansion joints is to provide flexibility in the piping system. They do this by allowing for movement in three main ways:
  • Lateral movement: Metallic expansion joints can accommodate lateral movement, which is movement in a side-to-side direction. This is important in systems that are subjected to thermal expansion and contraction, as the pipes will expand and contract due to temperature changes.
  • Angular movement: Metallic expansion joints can also accommodate angular movement, which is movement in a rotational direction. This is important in systems that are subjected to vibration, as the pipes will vibrate due to the flow of fluid or gas.
  • Axial movement: Metallic expansion joints can also accommodate axial movement, which is movement in a back-and-forth direction. This is important in systems that are subjected to misalignment, as the pipes may not be perfectly aligned.
  • In addition to providing flexibility, metallic expansion joints also help to reduce noise and vibration, and they can protect against the effects of corrosion, erosion, and abrasion. They are often used in a variety of industries, including power generation, petrochemical, pharmaceutical, and food and beverage.

Cryogenic Ball Valves

Cryogenic Ball Valves

Cryogenic ball valves are a type of valve that is designed to function at extremely low temperatures, typically below -150°C. They are used in a variety of applications where low temperature fluids need to be controlled, such as in the storage, transport, and processing of cryogenic gases, such as liquid nitrogen, oxygen, and argon.

Cryogenic ball valves are equipped with special materials and features that enable them to operate effectively at such low temperatures. For example, the body of the valve may be made from materials such as stainless steel or aluminum that have low temperature properties, and the valve may be equipped with a special insulation material to prevent heat transfer from the environment to the valve. The ball and seat of the valve may also be made from materials such as tungsten carbide or ceramic that can withstand extreme cold and wear.

Cryogenic ball valves are used in a variety of industries, including chemical, petrochemical, oil and gas, and food processing. They are commonly found in cryogenic storage tanks, pipelines, and processing equipment. They are also used in research and development facilities, medical facilities, and other industrial settings where low temperature fluids need to be controlled.

Cryogenic ball valves are used in a variety of applications that involve the handling of materials at extremely low temperatures. Some common applications for cryogenic ball valves include:
  • LNG (Liquefied Natural Gas) storage and transfer: Cryogenic ball valves are used to control the flow of LNG in storage tanks and transfer lines.
  • Cryogenic tanks and vessels: Cryogenic ball valves are used to control the flow of cryogenic fluids in tanks and vessels used for storage and transportation.
  • Refrigeration and air conditioning: Cryogenic ball valves are used in refrigeration and air conditioning systems to control the flow of refrigerants and other coolants.
  • Industrial gases: Cryogenic ball valves are used in the production, storage, and distribution of industrial gases such as oxygen, nitrogen, and argon.
  • Chemical and petrochemical processing: Cryogenic ball valves are used in the production and transportation of chemical and petrochemical products that require low temperatures for processing or storage.
