The basics of Built-in Motor Protection for Beginners

2021-03-11· The second type of internal protection is the thermistors or Positive Temperature Coefficient sensors (PTC). The thermistors are built into the motor windings and protect the motor against locked-rotor conditions, continuous overload and high ambient temperature. Thermal protection is then achieved by monitoring the temperature of the motor windings with PTC sensors. If the …

What is a Thermistor and how does it work?

2018-08-28· Thermistors, derived from the term thermaIly sensitive resistors, are a very accurate and cost- effective sensor for measuring temperature. Available in 2 types, NTC (negative temperature coefficient) and PTC (positive temperature coefficient), it is the NTC thermistor that is commonly used to measure temperature.

Another type of sensor, that is made using the PTC Thermistor, is ofcourse the temperature sensor. Here when these PTC are used, only their steep region of R/T characteristic is considered. Also, the resistance is regarded as a function of ambient temperature given that varistor effect is excluded. These sensors come in handy at places where temperature limit is needed for protection purposes.

H-377 - YSI

The H-377 uses a thermistor and resistor combination for a simple, yet precise temperature measurement of water or air. The thermistor is classified as a Negative Temperature Coefficient (NTC) thermistor. This means that as the ambient temperature increases, the resistance of the thermistor decreases. The resistance of the thermistor has a non-linear relationship with the ambient …
