PTC Exhaust Gas Temperature Sensor
Precisely detect temperature difference
PTC stands for "Positive Temperature Coefficient", meaning the sensor resistance increase as sensing temperature increase. PTC temperature sensor's resistance variation is in linear scale. PTC EGT sensor integrates PT200 sensing element construct via thin film process. Its characteristic indicates 200Ω (Ohm) when temperature is at 0°C. PT200 exhaust gas temperature sensor can accurately detect temperature difference and feedback its signals in voltage to ECU (Electronic Control Unit) to oversight vehicle exhaust system's overall condition.
Ceradex's PTC temperature sensing element are made from PT200 in accordance with OEM standards. And with high-temperature tolerance sensor body materials, it can withstand temperatures up to 900°C.
