Characteristics
■Alternative for standard micrometer drives:13mm/25um travel
■Piezoelectric travel to 25um
■Sub-nanometer resolution(<1nm)
■Dynamic operation
p83 is micrometer drives with integrated high-resolution piezo linear drives. It can be operated manually. 13mm/25mm travel, and resolution up to 10um. By controlling the piezo voltage, the micrometer tip is automatically moved in and out relative to the manually set position.Travel of the piezo actuators is up to 25um, resolution<1nm. It can therefore be used as a remotely controlled fine positioning element.
Work principle
A sophisticated wire EDM(electric discharge machining) flexure motion amplifier doubles the displacement of a piezo linear actuator. It also serves as a linear guide to the micrometer drive, which is moved back and forth when the piezo drive voltage is changed. This design is compact and mechanically stable.
P83 piezoelectric micrometer drive can be mounted like a micrometer drive by clamping around the sleeve.
