SRH Duct Mount Relative Humidity Sensor

Setra’s SRH relative humidity sensors are housed in a polycarbonate 94 V-0, NEMA 4 enclosure, suitable for harsh environments. It offers the easiest replaceable sensor tip. No calibration is needed because each sensor module is factory calibrated.

Overview

Setra’s SRH duct mount relative humidity sensors offer 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 sensor is housed in a polycarbonate 94 V-0, NEMA 4 enclosure making it suitable for harsh environments. The SRH duct mount sensor gives the user the choice of 2%, 3% and 5% RH accuracy to meet the requirements of typical HVAC applications. It 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.

The SRH offers the industry’s easiest replaceable sensor tip. Removing it requires no special training and can be easily replaced by the end user. No calibration is needed because each sensor module is factory calibrated before shipping, reducing downtime during service intervals.
