Unauthorized modifications are prohibited! The product must not be used in relation with any equipment that in case of a failure may threaten, directly or indirectly, human health or life or result in danger to human beings, animals or assets. Ensure all power is disconnected before installing. Do not connect to live/operating equipment.Please comply with • Local laws, health & safety regulations, technical standards and regulations • Condition of the device at the time of installation, to ensure safe installation • This data sheet and installation manualRemarksRefrain from touching the sensitive humidity sensor/element. Touching the sensitive surface will void warranty.For standard environmental conditions the manufacturing accuracy specified in the datasheet will be covered by the calibration warranty for two years. When exposed to harsh environmental conditions such as; high ambient temperature and/or high levels of humidity or presence of aggressive gases (i.e. chlorine, ozone, ammonia) the sensor element may be affected and readings may be outside specified accuracy. Replacement of deteriorated humidity sensor due to harsh environmental conditions are not subject of the general warranty.Accessoriesmounting platedowelscrewsRain covercable gland nut conduit 1/2" NPTApplication Notice for Humidity SensorsScope of DeliverySensor Datasheet22UTH-51..www.belimo.com22UTH-51.. • en-us • 2018-01-08 • Subject to change4 / 5Wiring DiagramrHRelative humidityabsHAbsolute humidityEntHEnthalpyTPkt/DewDew point the adjustment of the measuring ranges is made by changing the bonding jumpersthe output value in the new measuring range is available after 2 secondsSettingrange [°C]range [°F]FactorysettingExport Media AP WebS0-40°C to 60°C-40°F to 160°FS10°C to 50°C40°F to 140°FS2-15°C to 35°C0°F to 100°FS3-20°C to 80°C0°F to 200°FSensor Datasheet22UTH-51..www.belimo.com22UTH-51.. • en-us • 2018-01-08 • Subject to change5 / 5DimensionsNext >
