Description
The PRO-BAR Series provides economical, high-visibility 50-
segment bar graph 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
bar graph is horizontal or vertical. The housing is sealed to IP65
(NEMA-4) from all sides.
LED bar graph 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.
Bar graph 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 bar graph and digital meters.
