RdF Model 22454 Ambient Air Fast Response RTD Sensor

This temperature sensor is based on platinum resistance temperature technology. This is the same technology used for the most precise temperature measurements in aerospace, laboratory and research

The sensor combines accuracy with a fast response to temperature change in an air environment. The sensor provides accurate measurements for critical applications in controlled chambers, wind tunnels, cargo
bays, biological storage, air intake, environmental control, heat exchangers, exhaust flues, etc. The stainless steel enclosure protects the sensor from corrosive environments. The perforated sheath protects the sensing element from foreign material
