CCS – 646GE Series Pressure Switch
Description
The hazardous locations CCS – 646GE Series Pressure Switch is a rugged, heavy duty, all aluminum gage pressure switch. Similar to the 604 Series in design, the 646GE Series is rated to 15 Amps and UL/CSA explosion proof, Class I, Groups A, B, C and D, and Class II Groups E, F and G certified. It comes with high vibration and shock resistance utilizing Dual Snap® disc spring technology. Applications include:
• Oil & Gas
• Power Generation
• Fluid Management
• Chemical Refining and Processing
• Manufacturing Process
• Utilities, Water Treatment and Waste
• Safety Systems
Design Features
- Set points stay set – not sensitive to shock, vibration, temperature variations, or other ambient conditions
- No “tracing” of fluctuating pressures – no “teasing” of the electrical element. The switch is either “on” or “off.”
- Reduces the adverse effects of pump ripple, contact chatter, fatigue, premature wear, and other common switch problems
- Maximum life expectancy with lifelong reliability and precise repeatability assured
- A wide range of set points available in each switch model series.
