NTC Details

A Negative Temperature Coefficient (NTC) thermistor  is a non-linear resistor, which alter their resistance characteristics with every change in temperature in its environment, meaning that the resistance of the NTC decreases with increasing temperature. This characteristic is used in a bridge circuit to generate a signal suitable for further processing.


In order to pair an NTC with an RMS-MLOG-T10 device, 2 constants will need to be known:


1.The Beta constant:

The manner in which the resistance decreases is related to a constant known in the electronics industry as beta, or B.


2.The R25 value:

The standard reference temperature for NTC's is usually 25°C (R25), or the temperature of the thermistor body when supposed zero-power resistance is seen.


Both the Beta constant and the R25 value should be available on the sensor manufacturers data sheet.
