NTC Thermistors - Type KY2, KY3

Composite Thermistors

 

Composite thermistor types KY2 and KY3 contain one PTC and two NTC thermistor elements connected inside a plastic sleeve and encapsulated in a brass probe housing. Primarily intended for automotive applications, where a constant sensor resistance is required over a “normal” range of engine temperatures to give a fixed temperature gauge reading.

Options
  • Other resistance-temperature characteristics
  • Alternative housings * “POWER ON” resistance values measured with the thermistor assembled in a brass probe body. The probe is immersed in circulating oil (light engine type) up to the bottom of the hexagonal head and self-heated using the following circuit:
