If differential pressure across the filter exceeds the switch’s setting, the switch will trigger and an “off normal” signal will be sent to the BAS. Commonly, the BAS will monitor that binary input, ...

In systems where the airflow is kept at a constant level, this leads to a rise in the differential pressure across the filter bank. However, fans often begin to propel less air as the filter becomes ...

Units are available with four differential-pressure settings and screw into a 3/4-16 boss in a filter head. The single-wire design is suited for 6,000-psi systems and has passed a 1,000,000-cycle ...

The AST5300 wet/wet differential pressure sensor from American Sensor Technologies, Mount Olive, N. J., measures the difference in pressure between two points, and, when used ...
