Series 1700 Differential Pressure Switches were specifically designed to satisfy the demands of high volume original equipment manufacturers for a tough, dependable limit switch at a very low price. The Model 1710 uses Dwyer’s simple, time-proven method of mechanically coupling a sensitive 3″ diameter silicone rubber diaphragm to a versatile SPDT snap switch. The switch housing is precision molded of a high strength glass filled PPO which has excellent dimensional and thermal stability. This unique combination of existing and new technologies enables Dwyer to offer a limit switch priced less than comparable units without sacrificing performance. Installation is fast and simple with twist and tighten mounting screw slots, 1/4″ quick connect electrical terminals and dual size barbed pressure ports for 1/8″ and 3/16″ ID vinyl or rubber tubing.
For use with air and other non-combustible, non-corrosive gases, switches are UL and CSA recognized. Two models are offered with field adjustable ranges from .15 to .55″ w.c. and .50 to 7.5″ w.c. Units are rated for 2 psig maximum system pressure, temperature limit is 190°F and weight is only 4 oz.
