Optical and Solid State level switches provide unparalleled accuracy within precision engineering applications, such as medical diagnostics equipment.

Vibrating fork level switches typically operate using two piezoelectric elements built into a vibration tube. The first of these elements interprets vibrated pulse signals, and transfers the energy to the second element. This second element then converts the vibrated signal into an electrical output.

Yes, of course! All of our components are carefully designed and rigorously tested, so you can rest assured that they will not only be safe, they’ll be incredibly durable too.
