How it Works

THERMOWELLS

Thermowells are closed-end metal tubes installed pressure-tight into process vessels or piping, protecting temperature sensors from harsh industrial process conditions, such as flow-induced stress, high pressure and corrosive chemicals. In addition, thermowells allow the sensor to be easily removed from the process for calibration or replacement without requiring a process shutdown or pipe and vessel drainage. Of the many thermowell designs, the most common are threaded, socket weld and flanged.

SENSORS

High process temperature, pressure and vibration make temperature measurement devices essential in industrial environments. Consistent process control requires accuracy, repeatability and stability and, while several types of sensors may be used, RTDs and T/Cs are the most common. Temperature measurements often have the greatest impact on production efficiency, quality and safety, therefore careful consideration should be used when selecting sensors within a temperature measurement system.

TRANSMITTERS

Smart temperature transmitters accept signals from all industry-standard resistance temperature detectors (RTD) and thermocouples, converting measurement input signals to a 4-20mA output signal. Available in many housing styles and enclosures, these devices can be mounted with a sensor/thermowell assembly at the measurement point or mounted remotely, transmitting a hard-wired or wireless signal. For application flexibility, these transmitters can also be configured locally or remotely.
