Description click to view larger image The Weschler BG Series Circular Bargraphs include the BG241, BG251, BG261 and BG281. The panel footprint, shape and mounting meets direct retrofit applications for 4½” and 8¾” switchboard meters, as well as 6″ and 8″ pressure gauge meters. The electronics housing is identical for both sizes. Bars are available in red, green or amber for easy viewing. Weschler Bargraphs combine the visual indication of an analog gauge with the precision of a digital instrument. Digital displays are available with either 3½ or 4½ digit resolution. The 101 segment bar gives the operator a quick view of the measured signal and the control setpoints. Separate setpoint LEDs provide an added visual indication of control/alarm status. Signal direction is shown by two trend arrows. Setpoints and other parameters are easily entered from the front panel. Weschler Bargraph instruments can be configured for a wide range of input signals. Retrofit sizes are available for most panel and switchboard meters in use today. These instruments satisfy the high quality standards of the utility, OEM and process industries.
