GRILLO-DPC differential pressure controllers / volume flow controllers are used to measure and control low differential pressures of non-aggressive gases, especially air. A signal of 0…10V is available to the user as an analog output. Depending on the setting of the device, this signal has different meanings. If the instrument is used as a pressure sensor, the output signal is proportional to the measured pressure. As a volume flow sensor, the device provides a root-equipped output signal. In pressure or flow rate control, the output signal represents the manipulated variable of the PI control.

It is used, for example, in air conditioning technology for controlling fans, monitoring room pressure or controlling filters. In addition to the analogue output, an additional alarm output (open collector) is available for limit value monitoring or filter monitoring.

In addition to the analog output, an additional alarm output (open collector, max. 30 V / 30 mA or relay 250 Vac / 10 A) is available for limit monitoring or filter monitoring. The device provides a radiated output signal as a volumetric flow sensor. In the case of the pressure or volume flow control, the output signal is the manipulated variable of the PI control.
