Series TE duct and immersion building-automation temperature sensors are available with up to 18-in. probe length and thermistor or resistance-temperature-detector (RTD) outputs. They can be used to monitor air or water temperature throughout a building-management system or in an air-handling unit. They can be configured to have 8 plenum-rated cable with flying leads for variable-air-volume applications. Accuracy is is ±0.36°F @ 77°F for the termistor temperature sensor and ±0.28°F @ 32°F for the RTD temperature sensor. The temperature operating limit is -40°F to 302°F. —Dwyer
