GE CR127B4 - 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.
