Description

The MINICOMB® pressure switch series is a very compact-sized 30x30 pressure switch for measuring compressed air, low-viscous media and non-aggressive gases. 
It is based on a force-balance measuring system with bellows sensors actuating one switching contact. The force-balance measuring system with bellows sensors is friction-free and features high repeatability and very good longterm-stability. 

The MINICOMB® is available with pressure range 0,2 - 16 bar, -0,9 - 0 bar or -0,9...+1 bar. Sub-base mounting or female threads are availbe for connecting to the process, while 4-pin plug according to ISO 4400 or plug M12x1 are available for electrical connection. 

The MINICOMB® pressure switch series is approved for applications where PLc (Performance Level according to ISO 13849) is at least required (PLr) as well as for applications within hazardous area (zone 2 / 22 according to ATEX Directive 94/9/EC).

Operating Principle 

The principle of operation is the balance of forces. The working force within each bellow is counter-balanced by adjustable steel springs. This system actuates a microswitch when the working pressure overcomes the opposing force. The measuring system operates without any pistons or diaphragms, thus completly friction-free, resulting in minimal wear and no maintenance.
