Miniature differential pressure instruments from Orange Research are suitable for direct mounting on filters, pumps, tanks, hydraulic systems, fluid lines and similar equipment. The compact gauges and switches offer an alternative to full-size gauges. Instruments come in several styles, including standard dial-pointer gauges, differential pressure switches and gauge/switch combinations. Switch models allow users to activate alarms or control processes at predetermined setpoints. Differential pressure ranges can be selected from 0 to 25" w.c. to 0 to 80 psid at line pressures up to 3,000 psig for gas or liquid service.
