General Description
The EIT control unit is an electronic device for controlling pneumatic cleaning of the
Industrial Dust Collector Systems.
The pressure transducer mounted on the unit measures the differential pressure, allowing an
accurate analysis of the filter clogging status.
The control unit has 2 relay contacts, to signal alarm events, a 4-20mA self-powered output,
useful for transmitting the pressure value read to a remote device, and a large graphical
LCD, which displays the operating status and, through a membrane keypad, allows
configuration of the general parameters.
