Food, pharmaceutical and chemical processes often use tubular equipment to mix, transport or store materials. In these applications, it’s a good idea to keep any internal switches or sensors from protruding too far into the tube—where they can create a toehold for material buildup or impede flow. That’s where our newest pressure switch design comes into play.

This custom switch’s sensing element has been designed and manufactured to match the interior curvature of a specific food processing machine. The only part that protrudes into the flow within the machine is a low-profile, seamless seal that provides no place for materials to hang up during production.

While this particular flush-mount switch was designed for a specific use, the same approach can be applied to a wide variety of processing machines. We can alter the design of the switch for tubular structures with internal diameters as small as three inches.

We’ve also created a similar design for flush-mount pressure transducers.
