Wintersall Bellows Actuated Pressure Switch

GE CR127A13 – Bellows Actuated Pressure Switch

CR127 industrial pressure switches are designed for pilot-duty applications in control systems of hydraulic and pneumatic equipment. The bellows actuated forms, used with low-pressure applications of air, water and most hydraulics, are applied primarily on machine tools and welding equipment. Piston actuated forms are designed< for use with high-pressure hydraulics such as lubricating systems. Both bellows and piston forms must be used within their maximum safe pressure range which should be greater than line pressure including pressure surges. Although the switches are furnished with an orifice to protect against minor surges, a surge reducer should be used for protection against greater line surges. Also, a customer ground connection is provided within the enclosure.
