Setra Systems, a leading designer and manufacturer of pressure measurement devices, recently introduced its new Model SRH Humidity Series product line. The product line is designed to measure relative humidity in a room, duct or outside and is available in accuracies of ±2%, ±3%, and ±5%, featuring a replaceable sensor tip that ensures an accurate, calibrated, and cost effective humidity control system.

Setra’s humidity sensor family consists of a wall display, duct mount, and outside air unit. This product line is designed to complement Setra’s pressure transducers and current switches while expanding the solution opportunities for the HVAC/building automation market and other relative humidity monitoring applications. All models provide excellent reliability via a unique and established ASIC that is also used in Setra pressure transducers. Also, Setra’s robust, proven capacitive sensor technology is capable of full-scale 0 to 100% RH measurement.

The field-replaceable sensor tips are easily removed in all three models, allowing the end user to replace the sensors on-site. This essentially eliminates time consuming and costly factory calibration, while reducing downtime during service intervals.  Additionally, the duct mount probe is easily accessed by removing the front cover, pulling out the sensor board assembly, 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.
