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.

 

Thermistor overview:

oVery robust,

oInexpensive,

oSelf-powered, does not need external excitation,

oNot very accurate,

oInhomogeneities in wires may cause unexpected errors...

 

RTD overview:

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,

oMore fragile...

 

Rotronic recommend using Pt100 sensors for all applications where accuracy is critical.

 

Rotronic offer both Pt100 and NTC dataloggers.

•Pt100: RMS-LOG-T30-L & RMS-LOG-T30-868/915.

•NTC: RMS-MLOG-T10-868/915.
