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
• Water-tight
