Tiny force sensor is a sensitive sort

High sensitivity and small size simplifies the accurate monitoring of very small forces in complex, precision assemblies.

The Kistler Type 9215 is an exceptionally small piezoelectric force sensor for tensile and compression forces ranging down to a few millinewtons.

With a front, external diameter of only 5mm, the Type 9215 is the smallest force sensor in its class but has extremely high rigidly against lateral forces and a measuring range from -20 to +200N with two calibrated ranges (10 and 100%).

The sensor body has an M5 x 0.5 external thread and the force is transmitted via an M2 threaded axial hole at the front of the sensor.

Ideally suited for use in constricted spaces, the very small size makes the sensor especially suited to the cost-effective testing of small switches, pushbuttons, connectors and springs.

Miniature measuring platforms and sensor arrays can be produced with grid spacing as small as 7.5mm allowing a number of components to be checked simultaneously.

Typically, a simple rig can test all of the keys on a mobile phone in a single operation.

In research and development applications, the high sensitivity and small size simplifies the accurate monitoring of very small forces in complex, precision assemblies such as micromanipulators.
