PRESSURE GAUGES DPF 20 REG
Greatest flexibility in the comtrol and management of an inverter: display, 3 relays, analog output and PID regulation.
The DPFREG20 digital indicator is a device for measuring, displaying and controlling (with PID regulator) the differential pressure.
The pressure is controlled by a modulated output signal which may be analog (4-20 mA) or digital (ON-OFF type).
The instrument has the capability for piloting a remote device (such as an adjustable frequency drive - inverter - or a valve) in order to mantain the preassure measured by the sensor inside the instrument constant at a preset value. The instrument also has 3 relay outputs and the status of each of the 3 relays is indicated by three LEDS on the instrument front panel.
The DPF20 REG may also include (on demand) an interface for digital communication to exchange of data with remote instruments as PC or PLC.
It is available both for external installation (DPF-20 REG) and on the control panel’s front door (DPF-25 REG).
