Diaphragm pressure switch 300 series

differentialNPT 1/2NPT 1/4

The Series 300 Pressure Switches offer accurate, reliable switching in a robust cast enclosure. Having a width of only 70mm these switches are ideally suited for applications where space may be limited. The design allows for any number of these switches to be mounted in a row whilst still providing easy access to the electrical entry at the top of the switch and the process connection at the bottom. COMPREHENSIVE RANGE The Series 300 includes switches for monitoring both pressure and vacuum. The ranges available from -1 to 600 Bar cover all medium to high pressure industrial applications. With a choice of aluminium or stainless steel IP66 housings these switches are equally well suited for mounting on-site or use in panels. Compatability between the ‘wetted parts’ of the switch and your process can be assured with a number of options available for both the process chamber and diaphragm materials. LOW SWITCHING DIFFERENTIALS These switches make extensive use of the Rototherm precision pilot valve (PPV) as the prime sensing device to detect the process diaphragm movement. This valve provides a final switching differential equal to that obtained by the use of electrical microswitch – typically below 2% of the range.
