BW051P 51-Segment Circular Array

The BW051P enclosure 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.

For control applications, the optional set point/relay module provides on/off and differential gap control and annunciation using three set points. The optional digital display reads to 10 percent over- and underrange.

An optional temperature measurement module makes the instrument a direct-reading indicator for E, J, K, and T thermocouples or 100ohm RTD, and an optional re-transmission module simplifies distribution of the temperature parameter throughout the system.
