Versatility and superior performances in the control of filters obstruction: display, 3 relays, hour-counter anc analog output.

The DPF20 digital indicator is an instrument for measuring, displaying and monitoring differential pressure.
The instrument is equipped with an analog output 0-20 mA / 4-20 mA o 0_5V / 0_10V (to specify in the order) so it can works as a transmitter for a remote process controller. There are three relays in output (free SPDT contacts) programmable and the status of each of the 3 relays is indicated by three LEDS on the instrument front panel. The DPF20 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) and on the control panel’s front door (DPF-25).
