BG Series Large Edgewise BarGraphs

BG Series Large Edgewise BarGraphs

The Weschler BG Series Large BarGraphs include single and multiple channel models BD101, PG101 and PG202.

These large BarGraphs directly retrofit Hays, Bailey and Dixson draft gauges. Bars are available in red, green or amber for easy viewing. Weschler's LED BarGraphs combine the visual indication of an analog instrument with the precision of a digital instrument.

The BD101 BarGraph has a 12" edgewise display with 101 bar segments. Large digits and a wide viewing angle allow operators to easily monitor the signal from a distance. The BD101 can be ordered as a single channel unit or ganged into a multichannel unit to simplify installation.

The PG Series BarGraphs have a 10" edgewise display with a 51 segment LED bar. One and two channel models are available. Setpoints and other parameters on the PG101/202 are easily entered from the front panel. Analog retransmit and digital communications are optional.

Weschler BarGraphs can be configured for a wide range of input signals. These instruments satisfy the high quality standards of the utility, OEM and process control industries.
