D系列管道式安装温湿度传感器手册
Humidity sensor DKFHumidity and temperature sensor DKKD Series Duct versionDescriptionfor humidity and temperature measurementwith calibrated dModuldynamic Mela® humidity sensing elementoutput of hx valuesequipped for on-site calibration using buttons and LEDseasy to installThe industrial versions DK and DW can be used at operating temperatures between -30 ... 80°C. The integrated hx processor uses the values of the relative humidity and the temperature to calculate the dew point, the enthalpy, the mixing ratio, theabsolute humidity or the wet-bulb temperature. Per the customer’s preference, any two of these are emitted at two analogue outputs using standardized signals.The core part of the D Series is the digital calibrated dModul, which processes the measurement values of relative humidity and temperature individually. The values are compared to the calibration values stored in the dModul and communicated digitally to the transmitter electronics, where they are processed to standardised current and voltage signals.The housings of the industrial versions provide protection in accordance with IP 65. Only a single screw is required to close it securely
