The PRO-BAR Series provides economical, high-visibility 50-segment bargraph displays for 4-20 mA or 0-10 V process signals. The scale measures a full 251 mm (10") for exceptional visibility over long distances. A units-of-measure window allows the scale to be labeled. Scaling is by means of easy screwdriver adjustments.

The PRO-BAR housing is made of polycarbonate and can be panel mounted or wall mounted. Installation can be such that the bargraph is horizontal or vertical. The housing is sealed to IP65 (NEMA-4) from all sides.

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 to bargraph and digital meters.
