THE-1002

Sensor: Duct Temp, Hum :- The THE-1002 is designed for use with building automation systems in commercial buildings, hospitals, museums, or other facilities requiring accurate measurement of relative humidity and temperature. It transmits separate relative humidity (RH) and temperature signals for use in temperature, humidity, or enthalpy-based control applications. This transmitter uses a state-of-the-art silicon CMOS chip sensor, which provides much more durable and reliable performance than the older capacitive polymer sensor. It responds within seconds to changes in humidity with a very high degree of accuracy. The THE-1002 offers three different standard humidity outputs (0–5 VDC, 0–10 VDC, or 4–20 mA), any one of which may be used per application. This reduces the need to stock multiple transmitters to accommodate several output requirements. The THE-1002 also contains a thermistor for measuring duct temperature. The 10,000 ohm (@ 77° F) thermistor provides precise, stable temperature sensing. It operates from 24 VAC supply voltage. The sensor probe is filtered to reduce the possibility of contamination from airborne dirt and dust. An integral housing affords multiple 1/2-inch conduit knockouts for ease of wiring during installation. NOTE: For wall-mounted applications, see the THE-1102 or THE-1105.
