The Veris HW2XA2D wall humidity sensor provides accurate relative humidity and temperature monitoring for commercial HVAC and building automation systems. Its ±2% RH sensing accuracy and 10K Ω Type 2 thermistor support precise environmental control, improved occupant comfort, and efficient system performance. The replaceable thin-film capacitive element measures 0 to 100% RH with 0.1% resolution and recovers from full saturation to reduce maintenance downtime.
For broad BAS compatibility, the HW2XA2D offers selectable 4 to 20 mA, 0 to 5 V, and 0 to 10 V analog outputs. It operates on 24 VAC, ±20%, at 50/60 Hz with a 2.0 VA power requirement and Class 2 wiring.
The sensor is rated for air exposure from -40°F to 140°F, with normal operation specified from 32°F to 122°F and 0 to 95% RH non-condensing.
A matte-white, high-impact ABS enclosure, IP20 protection, and screw terminals for 18 to 24 AWG wiring support dependable wall-mounted installation.
UL Listed, CE, and UKCA markings, along with EN61000 Series industrial immunity compliance, make the sensor suitable for offices, schools, museums, workshops, and other facilities requiring reliable humidity and temperature control.
Veris HW2XA2D directly replaces HWX3XSTD Sensor.
