BW051P 51-Segment Circular Array

For control applications, the optional set point/relay module in BW051P provides on/off and differential gap control and annunciation using three set points. The optional digital display reads to 10 percent over and under range. An optional temperature measurement module makes the instrument a direct-reading indicator for E, J, K and T thermocouples or 100-ohm RTD and an optional retransmission module simplifies distribution of the temperature parameter throughout the system.

It replaces all 41/2 -inch standard switchboard circular meters and is a direct replacement for the GE/ Yokogawa AB/DB40 and Westinghouse/Weschler K231/241 meters. This simplifies retrofit into existing systems without panel modifications.
