Description

The PRO-BAR Series provides economical, high-visibility 50-segment bargraph displays for popular process signals such as 4-20 mA, 0-10 mA, 1-5 V, and 0-10 V. The scale measures a full 250 mm (10") for exceptional visibility over long distances. A units-of-measure window allows the scale to be labeled.
The PRO-BAR housing is made of extruded aluminum and can be panel mounted, wall mounted, or suspended. Installation can be such that the bargraph is horizontal or vertical. When panel mounted, the front of the display is sealed to IP54 (NEMA-12).
LED bargraph meters are popular replacements for sight-glass or moving coil contact displays. With LEDs, there are no moving parts to wear, visibility is excellent, and the cost of maintenance is very low.
Bargraph meters are an ideal means to display relative values, with no need to interpret numerical data. They can be augmented by digital panel meters or large-digit numeric displays when absolute readings are required. The same process signal can be applied bargraph and digital meters.
