High Over-Pressure Capability

  • Proof pressure is the maximum pressure that may be applied to the switch without causing permanent degradation
  • CCS switches will function to specification when proof pressure is applied
  • Competition definition states “switch may become inoperable” 

Repeatable and Stable Set Points — Set Point accuracy

  • Repeatability is the maximum set point deviation of a single pressure switch under one set of environmental and operating conditions
  • CCS switch repeatable: +- 1% set point
  • Constant rate competitive devices: +- 2% full scale

High Cycle Life

  • The CCS Belleville Spring reduces switch element mechanical wear which in turn prolongs contact life
  • CCS switches have no moving parts except during actuation and de-actuation 

Wide Range of Set Points

  • CCS offers products from vacuum to positive pressure including crossover vacuum to gage pressure switches
  • 28.5” Hg Vacuum to 16,000 PSIG
  • The CCS Belleville spring works at both the bottom and the top of adjustment range
  • With competitive constant rate devices, set points are only recommended at the upper  2/3 of the adjustment range 

Protection Against Environment

  • Hermetically sealed switching elements
  • Rated to NEMA 4, 4X, 7, 9, 13
  • Rated to IP 65, 66, 67, 68
