Model SRH Duct Mount Relative Humidity Sensor

Setra’s SRH duct mount humidity sensors offers optional active temperature with choice of 4 to 20 mA or user-selectable 0 to 5 and 0 to 10 VDC output and passive temperature with choice of thermistor or RTD output. The sensors are housed in a polycarbonate 94 V-0, NEMA 4 enclosure making it suitable for harsh environments. The SRH duct mount sensors gives user the choice of 2%, 3% and 5% RH accuracy to meet the requirements of typical HVAC applications. SRH duct mount humidity sensors features a removable sensor tip, NIST traceability and a durable capacitive sensor capable of a 0 to 99% full scale RH measurement and recovery of 100% saturation. Applications of SRH duct mount humidity sensors are HVAC/R control, Indoor Air Quality (IAQ), laboratories, antique preservation.

The SRH sensors offers the industry’s easiest replaceable sensor tip. Removing sensor tip requires no special training and can be easily replaced by the end user. No calibration is needed because sensor modules are factory calibrated before shipping, reducing downtime during service intervals. Duct mount humidity sensors can be ordered with either a passive (RTD thermistor) or active (analog) temperature output, enabling 2 measurements from 1 device. Units configured with the active temperature options feature jumper selectable Tspan ranges of 40oC, 50oC, and 60oC. The SRH comes with a 5 year warranty on the electronics and a 2 year warranty on the sensor modules, giving the user peace of mind over the life of the product.
