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.
