 Piezocryst and HBM introduce new piezo-electric force washers for industrial process control.
A new innovation in force measurement technology is being introduced to an audience of specialists at the SPS/IPC/DRIVES trade fair in Nürnberg. The two new force washers cover a force range up to 50kN and 140 kN and offer all the advantages of piezo-electric measurement technology: Extremely robust and virtually displacement-free, highly dynamic measurement in a compact size. The force washers offer innovation, which puts them above conventional rings. Due to their patented (patent pending) construction with a split membrane function, the housing becomes more symmetric and the actual membrane becomes more warp resistant. This characteristic elevates measurement safety during processes where the force introduction into the rings is critical (for example, from the retainer of a ball-bearing). In addition, this ring can be installed with positive locking, without influencing the measurement through friction on the inner ring surface. In conventional force washers, this often manifests itself in the form of an unwanted hysteresis.
The sensors already show an impressively high linearity under minimal tension, thus making it possible to measure even minimal forces with high overload security and exact precision.
In order to calibrate the force washers during assembly, HBM offers the factory calibrated force measurement chain CMC. The new rings are therefore the most consistent expansion of the sensor portfolio and fit right into the HBM system environment.
