How to Select a Temperature Transmitter for Harsh Industrial Environments
Temperature instruments used in industrial processes may be exposed to high temperatures, moisture, dust and changing environmental conditions. The right temperature transmitter helps maintain accurate measurements and reliable signal transmission to the plant’s control system. Choosing the right model is a matter of knowing the process, the installation environment and the existing equipment. Check Sensor Compatibility and Communication Temperature transmitters receive signals from sensors like resistance temperature detectors (RTD’s) and thermocouples and convert them to standard signals for monitoring and control systems. Before selection, check the supported sensor types, measurement range and accuracy specifications of the model. Communication is also of equal importance. A 4–20 mA output is used for many industrial applications, with compatible models supporting HART or FOUNDATION Fieldbus. The selection of the required option depends upon the type of plant control syste...
