11/2025 • We reserve the right to make technical changes. • Digital sensor element for humidity, temperature, air pressure All key sensor characteristics, settings, and adjustment data are saved in the sensor element itself. • Plug-in sensor element: Spare elements are inexpensive; a replacement can be fitted on site quickly and easily by virtually anyone; it will be fully accurate straight away needing no special adjustment. • Digital transfer of measured values from the sensor element to the transmitter • Four climate variables can be measured: Double analog output for temperature and one humidity variable relative humidity / dewpoint / mixture ratio. The air pressure dependent humidity values are automatically compensated for air pressure (the air pressure is measured directly at the measuring point in the • The transmitters can be configured via the internal display and the keypad. • The analog output type (10 V or 20 mA) can be selected (via the keypad); the analog output range can be programmed. • Display of measured value, channel, units, humidity range, analog start, analog end, and analog type • The sensor tube can be connected either directly by plugging onto the transmitter itself or via a connecting cable. • Suitable for conduit mounting or wall mounting Operative range Sensor -20 to +80 °C, 5 to 98 % RH Humidity sensor Sensor CMOSens® technology Fixed measuring period / output period approx. 3 seconds Accuracy ±3 % RH in range 10 to 90 % RH (incl. hysteresis) ±5 % RH in range 5 to < 98 % RH Sensor operating pressure Atmospheric pressure Response time T63 typical 8 seconds at +25 °C, 1 m/s (without filter) Temperature sensor Sensor CMOSens® technology Fixed measuring period / output period approx. 3 seconds Response time T63_typical 20 seconds (without filter)_ Double analog output Digital-to-analog converter (DAC) electr. isol. 0 to 10 V, load >100 kilohms 0 to 20 mA, load <500 ohms Output type Resolution Accuracy Temperature drift Time constant Connection Cable, via screwless clamp connector, with cable bushing Cable diameter 2 to 5 mm Standard equipment Display, internal Operation, internal Power supply DC voltage Current consumption Connection Cable, via screwless clamp connector, with cable bushing Cable diameter 2 to 5 mm Mechanical design Sensor tube Protective cap Housing Dimensions Protective class Stainless steel, diameter 12 mm SK7, metal-mesh filter Die-cast aluminum, closed cover 100 x 100 x 60 mm (LxWxH) IP65 (with sensor tube and connecting cable plugged in)
