Industrial Hazardous Area Products
High Over-Pressure Capability
Proof pressure is the maximum pressure that may be applied to the switch without causing permanent degradation
CCS pressure 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
