A high quality, self-aligning springloaded/- piston sensor is the heart of each BETA switch. The limited piston travel transmits pressure at the process diaphragm directly to the microswitch, with no intervening linkages or mechanisms while providing full protection against high overrange pressure.
The piston sensor is isolated from the process fluid by a diaphragm and static O-ring seal and retained by a process connection port. These (3) are the only process wetted parts and are available in an extensive range of materials.*
(*) A BETA vacuum switch contains also a vacuum piston and spring (SS 316) on the wetted parts side.
