The Omega 44004 thermistor is an available option on all Trilogy I-Force linear servo motors. The general specifications and resistance versus temperature characteristics can be found in the wiring option diagrams in the Trilogy catalog. Below is an example of a wiring option with the Omega 44004 thermistor.
And below is a resistance vs temperature table for the Omega 44004
The Omega 44004 is an NTC (Negative Temperature Coefficient) thermistor as opposed to a PTC (Positive Temperature Coefficient) thermistor. An NTC thermistor's resistance decreases as temperature increases. Some advantages of a thermistor over the standard thermostat is speed of response to temparature changes, accuracy and repeatability.
