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 portfolio of linear membrane sensors ranges from standard products to products that have been adapted according to your exact requirements.

Tell us the length, width, resistance value as well as the mechanical and electrical orientation 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.
