HUMIDITY TRANSMITTERS
Model SRH
Relative Humidity Sensor
DESCRIPTION
The Model SRH Humidity Series include wall mount, duct
mount and outside air congurations in 2%, 3%, and 5%
RH accuracy. The SRH Series oers optional active tem-
perature with choice of 4 to 20 mA or user-selectable 0 to
choice of thermistor or RDT output. Humidity transmit-
ters congured with active temperature option feature
jumper selectable Tspan ranges of 40°C, 50°C, and 60°C.
All models feature a removable sensor tip, NIST traceabil-
ity, and a durable capacitive sensor capable of full scale
0 to 100% RH measurement. All models can withstand
100% saturation without losing performance.
Replacing the removable sensor tip requires no special
training and can be easily replaced by the end user. No
calibration is needed because each new sensor module
is factory calibrated before shipping, reducing downtime
during service intervals. As an example,the duct mount
probe is easily accessed by taking o the front cover, pull-
ing out the probe and replacing the sensor tip. This same
procedure can be performed on the wall mount and out-
side air models. An additional benet for duct and out-
side air applications is the sensor module can be replaced
without having to remove the unit and disconnect the
wiring conduit.
