How do I connect a Thermistor to a PLC?
Assigned a new task to add a thermistor measurement to your PLC system, you ask yourself “How do I connect a Thermistor to a PLC?”.
A thermistor transmitter allows a thermistor to be signal conditioned to be more easily used.
A thermistor is a low cost accurate temperature sensor. It is easily connected using standard copper wire.
A thermistor transmitter converts the thermistor resistance change to 4-20mA current change. The 4-20mA signal allows the thermistor, when using a transmitter, to be connected to a PLC. This allows a thermistor to be used as a part of a modern control system.
