Membrane sensors

Description

Membrane sensors are characterised by their particularly flat design. They are hermetically sealed and are easy to attach with an adhesive film that can be affixed to the back on request.

Our rotatory membrane sensors can be individually adapted to your specific requirements. Tell us the desired values such as diameter, angle of rotation and resistance as well as the mechanical and electrical values and we will produce exactly the right sensor element according to your specifications.
We produce individual samples all the way through to large series containing hundreds of thousands of items.
