Internet: www.galltec-mela.de D Series Sensors for Humidity and Temperature Measurement Type DI Room version Optional display • • • • Technical data Humidity measuring element output range Temperature measuring element dynamic MELA® humidity sensing element with integrated measuring chamber easy to install operating temperatures up to 60°C One special feature of the room version is the integral measuring chamber which is separate from the transmitter electronics. This ensures effective ventilation of the humidity and temperature sensing elements. The measured values are analysed based on individually recorded calibration values in the flash memory and are digitally processed to issue the voltage and current signals. The room version enclosure has a simple, robust locking mechanism. The transmitter electronics can be found in the upper section of the enclosure. Once the lower section has been installed in the chosen location, the upper section can be mounted and secured at a later date without the use of tools. output ranges 0...+50°C -30...+70°C 0...+100°C further ranges on request measuring uncertainty (UB=24 V DC ) voltage output 10°C...40°C current output 10°C...40°C Electrical data outputs voltage supply consumption of electronics (voltage output) min. load resistance (voltage output) Load at current output load RL (current output) electromagnetic compatibility Options display 2 lines 3 digits + 1 decimal place display approx. 21 x 40 mm² digit height approx. 8 m

output humidity output humidity output humidity output humidity output humidity output humidity The sensors of the D Series contain components, which can be damaged by the effects of electrical fields or by charge equalisation when touched. The following protective measures must be taken when the housing of the sensor is to be opened for connection: • • Before opening the housing of the sensor, ensure electrical potential equalisation between you and your environment. Pay particular attention to ensure that this potential equalisation is maintained while you are working with the opened housing....

Mounting instructions Position Install the sensor at a place where characteristic levels of humidity occur. The measuring chamber should be located in streaming air. Avoid installation next to heaters, doors or on outer walls. Avoid places exposed to the sun. When mounting the sensor on a patress, avoid external air getting onto the measuring elements of the sensor by sealing it appropriately. In order to insert the connection cable, prise the pre-cut part of the housing‘s base part open. In order to insert a on-wall cable, the bars of the immerged part of the housings side can be removed. Connection...
