Low Temperature Sensors

Stoneridge uses a thermistor sensing element whose resistance changes significantly and predictably with temperature change. The device is made of polycrystalline ceramic material that can produce either a negative temperature coefficient (NTC) or a positive temperature coefficient (PTC) resistance curve. The sensing device which is typically chosen for temperature sensing applications is a NTC thermistor.
