Motor thermal protection | KEB

Nov 12, 2018· A KTY temperature sensor is a type of silicon sensor that also has a positive temperature coefficient much like a PTC thermistor. However, the relationship between resistance and temperature, for a KTY sensor, is approximately linear. The operational temperature range can vary between KTY sensor manufacturers, but typically the range is -50°C ...

Introduction to Temperature Sensors: Thermistors ...

Jun 05, 2017· The PTC thermistor is not common for temperature measurement but is VERY COMMON when used as a self-resettable fuse. Another common temperature sensor is the silicon diode. It has a very linear temperature coefficient over the normal operating range a semiconductor is used in, typically 0 to 50 C. This range can be stretched some if needed.
