etra’s Humidity Sensor
(SRH) family consists of a
wall mount, duct mount,
S
product l ine is desi gned to
complement Setra’s pressure and
current products while expanding
the solution opportunities for
the HVAC/building automation
market and other relative humidity monitoring applications.
All models feature removable
sensor tips, NIST traceability,
and a durable capacitive sensor
capable of full-scale 0 to 100% RH
measurement.
The SRH product line offers accurate humidity with active or
passive temperature sensing
available in ±2%, ±3%, or ±5% RH
accuracy. Humidity transmitters
configured with active temperature option feature jumper- selectable Tspan ranges of 40°C,
50°C, and 60°C.
This product suite utilizes fieldreplaceable sensor tips that allow the end user to replace the
sensors on-site. This essentially
eliminates time consuming and
costly factory calibration, while
reducing downtime during service intervals. As an example,
the duct mount probe is easily
accessed by taking off the front
cover, pulling out the probe, and
replacing the sensor tip. This
further contributes to a more
user-friendly, lower cost product
line that is focused on customer
needs and ease of use.
Setra’s humidity sensors are
the ultimate product for any
HVAC installation and, combined
with our pressure and current
products, allow us to support a
one-stop, single source for any
customer. The SRH line is a natural progression that grew out of
our high quality line of pressure
transducers that also use the
same unique ASIC coupled with
a highly reliable capacitive sensor technology. This product line
marks the capstone in fulfilling
a complete HVAC solution and
boasts the same quality, delivery,
and innovation demanded of all
Setra products.

Key component of comprehensive
HVAC/R solution
The Setra humidity/temperature solution
is an important part of our overall HVAC/R
solution which also includes pressure and
current. This bundle of products has established Setra as a premiere HVAC manufacturer and a full-solution player for HVAC
customers.
Robust, proven capacitive sensor
The unique pairing of Setra’s proven
capacitance measurement technology
with its custom ASIC (used in thousands of
pressure devices) ensures reliable measure
of RH levels from 0 to 100%. As a result,
customers will experience better resistance to contamination, longer stability,
and minimal drift.
Attractive/ low profile enclosures
Design and aesthetics have always been
considered an important ingredient in any
new Setra product. The humidity family
consists of three configurations: wall, duct,
and outside air models. Great attention
was given to the look of the wall mount,
ensuring that it complements the décor
of any building. It is a space conscious
unit that takes up no more space than an
electrical outlet. The duct and outside air
models utilize a design that ensures ease
of both assembly and probe removal for
recalibration.
Three levels of RH accuracy 2%, 3%, and 5%
There are three levels of accuracy available for Setra humidity sensors: 2%, 3%,
and 5%. The sensors should not drift more
than 1% annually but it is recommended
that the sensor be checked each year to
ensure high accuracy and dependability.
