WIKA Additional Instructions Pressure Transmitter with CANopen Interface D-20-9 / D-21-9 38

7. Filter

The D-2X-9’s filter function offers many possibilities to customize the device’s internal signal for the

application.

Example:

Despite a superimposed sine (10 Hz-sine with 1 bar amplitude) the static pressure should be measured as

precisely as possible.

With a sample rate of 5 ms and filter value of 20, there is an averaging of the measured values of the last 100

ms.

Therefore the user receives the correct static pressure of 150 bar from the D-2X-9 output signal.
