For adjustable differential type, use two pressure switches by setting one for rising pressure and other for falling pressure. he above graphs show the variation range for resetting of the r. Switch. E.g. When 1S1-** pr. switch is Set at 8 bar rising pressure signal, the pr. switch will reset anywhere between 71 [8-9] bar to 75 [8-5] bar. Similarly If the r. Switch is set for falling pressure signal the variation range is applicable to rising pressure at which the pressure switch resets.
