Miniature differential pressure gauges are rugged, solid aluminum blocks that handle line pressures to 3000 psig. Differential pressure ranges are selectable from 0-25 in. water to 0-100 psid with full-scale accuracies of 5%. They are available in piston and diaphragm sensors. Switch models allow users to activate alarms or control processes at predetermined set points.
