ceramic base layer

Function
Depending on the water vapour partial pressure, more or fewer water molecules enter the porous polymer layer. The resulting changing capacity of the sensor is transformed into a moisture value and is shown in the display.

Sensor technology
The DP207 is equipped with a capacity polymer sensor. Advantages of the sensor:

• Fast reaction time
• Mechanically resistance
• Wide field of application

Where to use


You can use the DP 207 downstream of a dryer. Therefore you have two possibilities for installing the DP207.
