APPLICATION

The BOLL Differential Pressure Indicator is a robust and compact device

indicating the contamination level of

the filter elements.

The differential pressure between filter inlet and filter outlet is the measurable indicator for the contamination

degree of the filter element. When the

preset maximum value of differential

pressure is reached, the filter needs to

be cleaned.

The color of the disc segments visible

in the two displays indicates the contamination degree: The red segment

rises proportionally to the level of

contamination. When the segment is

completely red, the differential pressure limit is reached.

DESIGN AND OPERATION

Inside the device is a plunger which is

held in zero position by a spring. As

differential pressure rises with increasing contamination, the plunger is

displaced against the resistance of

the spring. By magnetic transmission

the display disc turns according to the

movement of the plunger and shows

more and more red segments. The

setting of the requested differential

pressure is effected by factory installation of a corresponding spring.
