Setra’s SRH outdoor humidity sensor offers active temperature with choice of user-selectable 0 to 5 or 0 to 10 VDC or 4 to 20 mA output as options and passive temperature with the selection of the thermistor or RTD output. The sensor is enclosed in a polycarbonate 94 V-0, NEMA 4 enclosure making it suitable for harsh environments. The SRH outdoor air sensor gives the user the choice of 2%, 3% or 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 from 100% saturation.
Replaceable Sensor Tip for Easy Calibration – The SRH offers the industry’s most convenient replaceable sensor tip. Removing it requires no specialized 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.
Active & Passive Temperature Outputs – The SRH can be ordered with either a passive (RTD Thermistor) or Active (Analog) temperature output, enabling two measurements from 1 device. Units configured with the active temperature options feature jumper selectable Span ranges 40°C, 50°C and 60°C.
Worry-Free 5 Year Warranty – The SRH comes with a 5-year warranty on electronics and a 2-year warranty on the sensor module, ensuring reliable measurement from your relative humidity sensor and temperature RTD over the life of the product.
