Switching pressure differential graph

range

ENGINEERING

These are non-adjustable differential type pressure switches. These pressure switches are generally used for setting eitherrising pressure or falling pressure signal.

For adjustable differential type, use two pressure switches by setting one for rising pressure and other for falling pressure.

The above graphs show the variation range for resetting of the Pr. Switch. E.g. When 1PS100-** pr. switch is Set at 80 barrising pressure signal, the pr. switch will reset anywhere between 71 [80-9] bar to 75 [80-5] bar. Similarly If the Pr. Switch isset for falling pressure signal the variation range is applicable to rising pressure at which the pressure switch resets.
