Tri-Color Edgewise Bargraph Meters – Weschler


The Weschler Instruments TriColor Bargraphs include the BG252TC, BH252TC, BV5ATC & BD101TC.  These meters provide the quickest way to spot problems in process control panels with bright changing colors. Quick identification of trouble conditions can help prevent equipment damage or production loss, thus reducing down time and maintenance costs, and improving operational safety. Each 40 segment LED (Light Emitting Diode) of the BG TC family has the ability to illuminate as Red (Danger), Yellow (Caution), or Green (Safe) condition. The bar color identification can be easily changed by the user, from the front pushbuttons or through a tamper safe mode. The fully programmable Weschler BG TC BarGraph™ fits the widest range of inputs and retrofits most edgewise switchboard and panel meters. Weschler’s instruments satisfy the high quality standards set forth by the utility, OEM, and process control industries.
