HarcoSemco’s Engine Inlet Temperature (T1) Sensors utilize precision Resistance Temperature Detector (RTD) elements to provide critical air temperature measurement to the engine control unit. Our T1 sensors are dual channel for redundancy, have fast response times, and proven performance under rigorous icing conditions and have been designed to withstand impact from inlet FOD traveling at high velocities. Furthermore, our sensors have been designed to withstand extreme vibration and shock environments for harsh aerospace applications.
