1.3 Layout of the humidity measurement
system
The measurement system consists of an evaluation unit and up to three hu-
midity sensors.
The evaluation unit is designed as a 19“rack which can take several plug-in
units. The evaluation unit can also be installed as a desktop device.
The humidity sensor consists of a sensor layer and an integrated tempera-
ture sensor, the fibre-optic cable and the plug connector, which also contains
the sensor´s adjustment data.
The humidity sensor is available in three standard dimensions: 36
mm,
100 mm and 225
mm. Sensors with length of 407mm and 458mm are avail-
able on request.
1.3.1 Operator controls and display elements
All operator controls and display elements are at the front side of the evalua-
tion unit. The device is not equipped with a mains switch. If required, you
have to disconnect the device from the mains supply (mains plug). If operat-
ed as a desktop device, the two front feet of the evaluation unit can be swiv-
elled out for easier operation and a better viewing angle.
1.3.1.1 Keyboard
The device is operated via touch-sensitive keys on the front side of the de-
vice (numeric and measurement variable keys) and via certain key functions
of the touch-screen. All keys are touch-sensitive, i.e. you don’t need to press
them, only touch them.
