The QGMTP is an internally preloaded piezoelectric open loop translation device capable of moving up to 105μm with very high resolution.
The actuators offer a very stiff design that is capable of generating blocking forces as high as 1000N (QGMTP-15). This characteristic enables the actuator to drive demanding loads of up to a maximum 10kg (QGMTP-15) in the Z-axis. Driving the QGMTP actuator over nominal range simply requires a 0V to 120VDC HV amplifier. However, if required, it is possible to achieve additional range by using a -30V to 150VDC capable HV amplifier.
If a small form factor and closed loop performance is required the QGMTP can be used in conjunction with a Queensgate’s position measurement system. This provides capacitive position sensing for sub-nanometre precision with the benefit of independent sensor placement from the actuator. This allows the freedom to mount the sensor plates at any convenient point on the host fixture.
