Setra's Humidity Sensor (SRH) family consists of a wall mount, duct mount, and outside air unit. This product line is designed 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 field-replaceable 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.
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.
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.
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.
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.
