Copied Explosion-Proof Differential Pressure Switch
Explosion-Proof Differential Pressure Switch
Series H3 Explosion-proof, Weatherproof Differential Pressure Switch, Chamber/Diaphragm Material - Stainless Steel Chamber and Fluoroelastomer Diaphragm, Adjustable Range - 10-180" w.c. , Switch - SPDT Snap Switch, Rated 5A @ 120/250 VAC, 30 VDC, Electrical Connections - 18 AWG x 18" Lead Wires Series H3 Explosion-proof, heavy duty, industrial unit has a unique new design which provides sensitivity to differential pressures as low as 10 inches of water , yet handles total pressure of 1500 psi . Unlike common differential pressure switches that use a piston-type motion transfer, the Series H3 utilizes a rotary motion transfer shaft that prevents a change in total pressure from causing a setpoint shift. Unit yields deadbands approximately 5% of range, with zero setpoint shift due to variation in working pressures. Friction is minimized and repeatability increased by allowing range spring to act directly on diaphragm plate. Rolling diaphragm design maintains constant effective area to further reduce friction. Diaphragm is allowed to "seat", allowing application of full rated pressure, up to 1500 psi , on either high or low pressure port, without damage. Special over-travel feature prevents overtightening of range adjust screw. Applications Water flow proving with an orifice plateLiquid filter statusDifferential pressure across chiller Perfect for monitoring differential water pressure on filters, chiller coils, and flow elements.
