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
