Protect Critical Processes with the REOTEMP Dual Mode Thermometer

The REOTEMP Dual Mode Thermometer (DMT) offers a convenient and efficient way to monitor temperature locally and remotely in a single, compact unit. Reotemp designed the DMT with two independent sensors in one thermowell, eliminating the need for separate instruments and simplifying calibration tasks. Operators can rely on the bimetal thermometer to see an immediate, on-site reading while gathering data from a built-in thermocouple or RTD for remote monitoring. This dual-sensor approach boosts reliability and reduces overall equipment costs since you do not have to install and maintain multiple temperature devices.

Each sensor in the Dual Mode Thermometer is NIST-traceable, which helps you confirm accuracy and adhere to strict quality standards. Reotemp encapsulates the sensors in a robust, stainless steel housing to protect them from harsh industrial conditions, and an optional liquid fill further shields the internal components from vibration and shock. The hermetically sealed bimetal thermometer includes a dampened helix that ensures smooth pointer movement, so you get an easy-to-read indication without erratic jumps. Because the DMT fits a standard thermowell, you can integrate it seamlessly into existing setups. This approach preserves your process integrity and allows quick instrument swaps when needed.

The DMT’s built-in thermocouple or RTD sensor transmits data to process controls, data loggers, or other remote systems. Depending on your operating range and accuracy requirements, you can select a thermocouple type (K, J, E, or T) or an RTD element (typically Pt100). Temperatures up to 1000°F are possible with certain thermocouples, while RTD versions measure up to 900°F. Reotemp also offers a 4-20mA transmitter output to tie the Dual Mode Thermometer into your plant’s control loops without extra converters.

Installation remains straightforward because you only insert one instrument into your existing thermowell instead of running separate lines for local and remote measurement. That design saves time during setup and prevents unnecessary process openings. For additional environmental protection, you can fill the thermometer with silicone, especially if you expect heavy vibration or washdowns. Reotemp’s rigorous testing ensures each Dual Mode Thermometer performs consistently, from -100°F applications to extremely high-temperature processes.

Users appreciate how this device streamlines calibration checks. You compare the local dial reading with the remote data to validate both signals at once, shortening maintenance windows and cutting the risk of measurement drift. The DMT’s versatile design serves industries such as food and beverage, petrochemical, energy, and pharmaceuticals, where accuracy and reliability are critical for quality control and safety. The REOTEMP Dual Mode Thermometer delivers a practical, high-performance solution for professionals who want complete temperature oversight in a single, durable package.

Industrial Thermowell Process Connection Types

This video covers the common types of thermowell process connections. The styles are referred to by what their process connection is.

The types are threaded thermowell, a flanged thermowell, a welded or weld-in thermowell, and a sanitary thermowell.

Threaded thermowells are commonly used when thermowell removal occurs infrequently. These wells are typically threaded into a welded fitting widely referred to as a weldolet on the pipe or vessel. Typical installations include smaller pipes or vessels where corrosion is not an issue.

Flanged thermowells are the preferred well for applications that require frequent removal or replacement due to corrosion or other hazards. Flanged wells will bolt to a mating flange installed on the process piping. Typical installations include large pipes with high pressure and high corrosion.

Weld-in thermowells are welded directly to the pipe or tank and provide a high-quality connection. Because being welded in, their removal is not easy, and they should only be installed when quick access is not required, and corrosion is not an issue. Typical installations include very high temperature and high-pressure applications, for example, a steam line or other non-corrosive applications.

Sanitary thermowells are generally fitted with a Tri-clamp or other clean-in-place connection. These thermowells also have a smooth surface which allows for easy cleaning and prevents contamination of the process: typical installations include dairy, food processing, and pharmaceutical industries.

The REOTEMP Model W Explosion Proof, Field Mounted, HART Temperature Transmitter

Process control instrumentation monitors and controls a process to maintain proper functioning standards and keep it within a proper functioning and safe operating range. Process variables are the parameters or quantities maintained to keep the process within desired and acceptable limits. Instrumentation systems compare process variables to a desired setpoint and then produce offsetting and corrective control outputs. 

Typical process variables are level, flow, temperature, density, pH (acidity or alkalinity), mass, and conductivity. 

Temperature is a measurement of how hot or cold something is, whether it's an object or a process medium. The temperature setpoint is the process variable's target value for optimum control, quality, and safety. In a process where the temperature stays within plus or minus 1 degree Celsius of 100℃, the setpoint is 100. 

Temperature transmitters are instruments that convert a weak thermocouple or RTD signal to a robust analog (4-20mA or HART) or digital (Profibus or Fieldbus) signal. The temperature sensor and the final control device communicate through the transmitter. Since transmitters provide more robust analog or digital outputs, external signal conditioning and amplification devices are eliminated, thus lowering costs.

The REOTEMP Model W Explosion Proof Field Mounted HART Temperature Transmitter includes a local display, HART compatibility, and a 4-20mA output. The field-mounted transmitter is available as a complete RTD or thermocouple assembly customized to your process. 

The REOTEMP Model W includes linearized temperature measurement with TC and RTD sensors (Pt100 and Ni100) inputs, local display, HART communication, and 4-20 mA analog PV output for individual, difference, or average temperature measurement. It can handle two RTD or TC input sensors, and up to 63 transmitters (HART 7) can connect in a multidrop communication setup.
