Supported Applications

The Omega UWRH Series consists of wireless temperature and humidity transmitters designed for dry, moisture-free indoor applications. These stand-alone devices monitor relative humidity and ambient temperature in permanent installations only; they are not intended for use as portable units.

Explicitly excluded environments include medical or nuclear facilities, as well as flammable or explosive atmospheres. The series is engineered to transmit sensor data wirelessly to a host receiver located up to 90 m (300') away.

Operating Conditions & Performance

The UWRH Series measures relative humidity from 0 to 100% RH and ambient temperature from -40 to 125°C (-40 to 257°F). Accuracy specifications are ±3% RH for relative humidity and ±1.5°C (±2.7°F) for ambient temperature.

Devices operate within an ambient temperature range of 0 to 50°C (32 to 122°F) and can be stored between -40 to 70°C (-40 to 158°F). Power is supplied by a included 3.6V Lithium Battery.

Communication occurs via Wireless RF Transmission at 2.4 GHz, sending relative humidity, ambient temperature, RF signal strength, and battery condition data. Installation requires maintaining a minimum distance of 20 cm from other radio transmitters or persons to prevent interference.

Configuration Options

UWRH-2: Standard wireless humidity/temperature transmitter housed in plastic.
UWRH-2-NEMA: Wireless humidity/temperature transmitter featuring a NEMA-rated enclosure for enhanced protection. This model is not CE compliant, whereas the UWRH-2 is CE compliant.
