Installation Instructions
1.0 GENERAL INFORMATION
Every SRH humidity sensor product is tested and calibrated before shipment. Setra’s
Humidity Sensor family consists of a wall mount, duct mount, and outside air unit.
This product line expands the solution opportunities for the HVAC/building automa-
tion market and other relative humid ity monitoring applications. All models utilize
a fi eld-replaceable sensor module, NIST traceability, accuracies of ±2%, ±3%, ±5%,
active or passive temperature sensing, and a durable capacitive sensor capable of
full-scale 0 to 100% RH measurement.
2.0 MECHANICAL INSTALLATION
2.1 Environment
The operating temperature limits of the SRH model are as follows:
Operating Temperature Range -40°F to 140°F (-40 to 60°C)
Storage Temperature -40°F to 158°F (-40 to 70°C)
2.1 Wall Mount
It is important to fi nd a place within a room where the transmitter can be ex-
posed to unrestricted air circulation that will represent the average humidity and
temperature within that space. Try to avoid any locations that may be exposed
to fumes, extreme temperatures, and high moisture content. Also, make sure the
location is on an indoor wall that is about 4 to 6 feet above the fl oor. For ease of
in.
