Humidity meas. transducer, humidity/temperature meas. transducerType: GRHUHumidity measuring transducerType: GHTUHumidity/temperature measuring transducerGeneral:The measuring transducer GHTU is equipped with 2 separate measuringtransducers for humidity and temperature.Specification : (humidity: GRHU... or GHTU...)Humidity sensor: capacitive thin-film polymer sensorMeasuring range humidity: 0 to 100% relative humidity - sensor maybesubjected to condensing, rec. range: 30 to 80% r.h. (for standard sensor).or higher or lower range choose option “high-humidity sensor”,recommended range for high-humidity sensor: 5 to 98% r.h.(When ordering option high-humidity sensor, please make sure to specifymain measuring range: eg 0 to 40% r.h. or 60 to 95% r.h. etc.)Other measuring ranges available (option) against upcharge.Accuracy:Linearity: standard sensor: ±2% from 30 ... 80 % r.h.high-humidity sensor: ±2% from 11 ... 90 % r.h.Hysteresis: standard sensor: ±1.5% r..high humidity sensor: ±1% r..Specification: (temperature: for GHTU only...)Temperature sensor: platinum resistance thermometer Pt100Measuring range temperature: 0 ... 70°C (standard)OPTION: -30 ... +40°C, others upon requestAccuracy temperature: acc to DIN 751 DIN cl.

(non- condensing)If there is a risk of condensation due to temperature changes, please useour encapsulated or lacquered types (optionally available).or outdoor application: please refer to heat absorption hat page 42Housing: ABS (IP65)Mounting position: sensor tube vertically pointing downwards tohorizontalSensor tube: anodised aluminium, Ø 14 mm, with screw-type bronzefilter 80 to 160 µm, nickel platedSensor length: 50 mm or 220 mm. (standard) - other length availableoptionally! Available sensor length "L": 300 mm, 400 mm, 500 mm.If device is to be operated at temperatures outside the range specified(0 to 70° C) make sure that electronics is not subjected to temperatureshigher or lower than that (eg use extra long tube to go through wall intocooling chamber, climatic chamber, open air etc.).Mounting: with mounting holes for wall mounting (accessible aftercover has been removed) or by means of plastic tube clamps, additionalwall support for direct mounting to channels, etc.Mounting distance for wall mounting: 70 x 50 mm (W x H)ixing screws for wall mounting: max. shaft-Ø 4 mmElectric connection: elbow-type plug acc. to DIN 43650 (IP65), max.wire cross section: 1.5 mm², wire Ø from 4.5 to 7 mmor outdoor application:Make sure to use special humidity measuring transducers withheat absorption hats.
