- To ensure longevity from the sensor, ensure adequate airflow is supplied directly to the sensor to avoid overheating or sensor failure. - Turbosmart HE sensor has an operation temperature window of -40C up to 170ºC (340ºF) junction temperature, for temperatures outside of this window the VOUT will revert to less than 2.5V - Temperature exposure above 260ºC (500ºF) can cause permanent damage to the sensor.
