The Beta Principle

A high quality, self-aligning diaphragm/piston sensor is the heart of a BETA switch. The limited piston travel translates pressure at the diaphragm directly to actuation of the microswitch, with no intervening linkages or mechanisms and with full protection against very high overrange pressure.

The piston sensor is isolated from the process fluid by a diaphragm and static O-ring seal, retained by a process connection port. These three are the only process wetted parts and are available in an extensive range of materials.

The Features


Safe, secure electrical hookup by clamp terminals

Standard earth terminal

IP 66 enclosure

Solid cover with gasket and captive screws


Highest Overrange protection.

Spring-loaded piston, excellent resistant against shock and vibration.

No pipe strains on the instrument to cause shift of setpoint, due to separate flexible stainless steel mounting bracket.


SGS certified Quality Assurance according to ISO 9001 - 2000 covers all switch manufacturing, Engineering & Design


ATEX: KEMA CE 0344 and PED: TÜV CERT. CE 0035 (For more; see also pages 16,17 and 18)


The wide range of process-wetted materials virtually eliminates the need for costly chemical seals
