Series 1700 Low Differential Pressure Switch
Brand: Dwyer Instruments, LLCThis product is no longer available, please contact Tech Support for a suggested replacement product.
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 0.15 to 0.55" w.c. and 0.50 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.
