Digital Draft Gauge

Manas Digital Draft Gauge

The 4475-PX Digital Draft Gauge accepts the draft pressure input as the signal and displays it in terms of mmwc. It also delivers 4 -20 mA output proportional to the draft. The Draft Transmitter is a field mounting unit and is a two wire system delivering 4 - 20mA output proportional to draft input. The transmitter can be mounted in the field thereby avoiding long lengths of impulse lines and also errors due to the lengths.
