The BGI Powered Process Indicators are advanced instruments which have been designed to accept all the standard process signals.

The input measurement is shown on a high contrast 31 element LED bar display with a display height of 76mm.
The BGI incorporates a CMOS dual slope integrating analogue to digital converter which is deigned to reject electrical interference that normally abounds in industrial environments. The front panel of the BGI is sealed to IP65 and the instrument includes screw terminal electrical connections.
