Internet: www.galltec-mela.de D Series Sensors for Humidity and Temperature Measurement with calibrated dModul Type DK Industrial version, duct version Optional display • dynamic MELA® humidity sensing element • output of all hx values • calibrated dModul for humidity and temperature measurement • in situ alignment • easy to install • operating temperatures up to 80°C • optional USB interface 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.

(Instruction for transmitters without USB interface) During the in situ alignment the sensor does not necessarily have to be taken out of the control circuit. We offer humidity standards for alignment of the sensors (page 5: Accessories). Before calibrating the sensor, standards should remain at least 2 hours on the sensors. The temperature must remain constant during this time. For the correct temperature according to the humidity standard used, please refer to data sheet F5.2 Humidity Standards. During calibration temperature and humidity must remain constant. During calibration,...

Option: transmitter USB interface Figure 1 General information: The following settings can be made using the „Galltec-Mela USB Configuration Software“ and a standard micro USB cable. The transmitter is powered via USB. Except for adjustments, the transmitter requires no power via a power supply unit.
