Grubatec-DPC differential pressure controllers / volume flow controllers are suitable for measuring and controlling small differential pressures of non-aggressive gases, especially air. A signal of 0...10V is available to the user as an analog output, the meaning of which varies depending on the setting of the device. When used as a pressure sensor, the output signal is proportional to the measured pressure, while the device provides a square root output signal when used as a volume flow sensor. When used as a pressure or volumetric flow controller, the output signal serves as a manipulated variable for PI control.

The additional Modbus RTU interface is intended for the digitalization of industrial processes. All device parameters can be read and written with the Modbus RTU interface.

A 0...10 V signal output is available for direct analog processing. This signal can be configured as a linear / square root measurement signal or as a manipulated variable of the closed control loop.

It can be used, for example, in air conditioning technology to control fans, monitor room pressure or control filters.
