Piezoelectric force washer is rated to 20kN

Paul Boughton

HBM is expanding its CFW series of piezoelectric force washers with a 20kN version to meet the demand for measuring lower nominal (rated) forces. This latest force washer has a diameter of 14.5mm and a height of 7mm, making it very compact in relation to its nominal force. This allows it to be easily integrated in applications, even where very little space is available.
Piezoelectric force washers use a measurement principle where the sensitivity does not depend on the nominal force. This makes this type of force washer suitable for measurements in partial load ranges where greater resolution is required. Typical applications for the CFW 20kN include the monitoring of assembly processes, compression processes or dynamic applications in the test sector.
The sensor has a symmetrical design to give good linearity and it provides simple and robust mounting because the inner and outer ring of the sensor can be connected solidly to the surrounding construction.
In common with the other sensors in the CFW series, the CFW 20kN has a very small displacement, which results in very high stiffness and excellent dynamic properties.

HBM's latest piezoelectric force washer is very sturdy and is suitable for applications in tough industrial environments where its IP65 sealing is a necessity. The sensors are operated together with the CMA series charge amplifiers or the CMD digital charge amplifiers, which are also suitable for use in tough industrial environments.
