The Rotronic Monitoring System can work with various temperature sensors. However, mainly Pt100 and NTC sensors.
A Pt100 is a RTD (Resistance Temperature Detector) and an NTC (Negative Temperature Coefficient) is a thermistor.
oSelf-powered, does not need external excitation,
oNot very accurate,
oInhomogeneities in wires may cause unexpected errors...
oAre more accurate, linear and stable than thermocouples,
oExtension wires can be copper wires,
oMore expensive than thermocouples,
oNeed a known excitation current suitable for the sensor type,
Rotronic recommend using Pt100 sensors for all applications where accuracy is critical.
Rotronic offer both Pt100 and NTC dataloggers.
Here is an overview of the various sensors:
