CCS Dual-Snap Pressure and Temperature Switches (Ex)
CCS Dual-Snap Pressure and Temperature Switches (Explosion-Proof)
The CCS Dual-Snap pressure and temperature switches are engineered to deliver exceptional performance in demanding environments. These switches leverage the innovative Dual-Snap principle, ensuring reliability, precision, and durability.
The Dual-Snap principle: Innovation and reliability
The success of CCS switches is built on a unique mechanism: a preloaded disc spring that snaps under pressure and returns to its original position upon pressure relief. This results in a consistent and reproducible switching point, unaffected by external factors such as:
- Shocks up to 10G
- Vibrations
- Ambient temperatures
With a tolerance of just 1%, the switch operates at its originally set pressure even after years of use. This includes the “dead band,” eliminating the need for long-term recalibration.
Technical Specifications
CCS Dual-Snap switches are designed to perform optimally, even in extreme conditions:
- Test pressure: Up to 1700 bar
- Adjustment range: From 28″ vacuum to 1100 bar
- Temperature range: -39 °C to 332 °C (down to -54 °C according to GOST standards)
Certifications
