When to Use an RTD vs. a Thermocouple Temperature Sensor

WebRTDs are special resistors whose resistance value changes with temperature in a known way. RTDs are connected to the temperature recording or process control instrumentation using ordinary copper instrumentation cable. Thermocouple wire is not required to … WebRTD’s, thermocouples, and transmitters function at power levels below the threshold of danger. A signal loop terminating at these devices may be deemed “intrinsically safe” if it is incapable of ignition under four conditions: normal power levels, faults in the control room, faults in the signal line, and faults in the sensor or transmitter.
