GRILLO-DPC differential pressure controller is used 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. Depending on the setting of the device, this signal has different meanings.
The range of application is e.g. in air conditioning technology for the control of fans, room pressure monitoring or filter control. For limit value monitoring or filter monitoring, an additional alarm output (open collector) is available in addition to the analog output.
In control mode, the setpoint of the DPC310 can now be adjusted dynamically. This can be done by an external input of a 10 V DC signal or in combination with a temperature sensor. Pressure and flow rate are thus no longer solely responsible for fan control, but other factors, such as the outside temperature, can play a role.
