The KMC Controls Model THE-1002 duct-mounted
humidity transmitter is designed for use with
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 now uses a state-of-the-art silicon
CMOS chip sensor.
This provides much more durable and reliable performance
than the older capacitive polymer sensor. Plus, it
responds within seconds to changes in humidity with
a very high degree of accuracy. Able to accept VAC
or VDC supply voltage, the THE-1002 offers three different
standard outputs, any one of which may be used per
application. This reduces the need to stock multiple
transmitters to accommodate several output equirements.
The THE-1002 also contains a thermistor for measuring
duct temperature. The 10,000 ohm (@ 77° F) thermistor
provides The THE-1002 also contains a thermistor for
measuring duct temperature. The 10,000 ohm (@ 77o
F) thermistor provides precise, stable temperature
sensing. The sensor probe is filtered to reduce the
possibility of contamination from airborne dirt and
dust. An integral housing affords multiple 1/2"
conduit knockouts for ease of wiring during installation.
