The Class 9012 Type G pressure switches are UL Listed and CSA Certified as industrial control equipment. They are used to interface pneumatic or hydraulic systems with electrical control systems by opening or closing electrical contacts in response to pressure changes in the system. They have outstanding repeatability and drift performance. Their efficient design uses durable, low mass components for excellent performance under heavy duty vibration and shock conditions.
Pressure switches are used in a wide variety of applications such as: compressors
Generally, Class 9012 pressure switches can be used in any application where electrical contacts must open or close in response to a system pressure change, within the electrical and pressure ratings of the switch.
Two typical functions of a pressure switch are to:
Monitor the pressure in the system. The switch can be used as either an interlock that will sequence operations in an automatic system, or to give an audio or visual signal, typically an alarm of an undesired condition, at predetermined pressures.
Control the pressure in the system by starting and stopping a pump or a compressor at predetermined pressures. Normally a switch with a nonadjustable differential is used in applications that monitor the pressure. An adjustable differential switch is usually necessary in applications that require the switch to control the pressure.
