675DES Series Pressure Switch

Brand: Custom Control Sensors, LLC
Request Information
Does not ship to OH, United States

The Hazardous Areas 675DES Series is a low range differential pressure switch designed with a large diaphragm, specifically for very low pressure settings (inches of water).

The switch Series sets the market standard for meeting extremely low pressure applications, exceeding any other mechanically based sensor technology.

It is UL/CSA Explosion-Proof, Class I, Groups A, B, C and D, and Class II Groups E, F and G certified. It also has high vibration and shock resistance utilizing Dual Snap® disc spring technology.

Features
  • Highly reliable and stable devices utilizing the CCS Dual-Snap® Belleville disc spring design pioneered by CCS
  • Aerospace-grade engineered technology
  • Convenient field set point adjustment
  • Vibration and shock resistant up to 20 G’s
  • Technology tested to 1,000,000 cycles
  • High over-pressure capability (System and Proof)
  • Certified Explosion-proof hermetically sealed electrical assembly for environmental protection
