To simplify the use of its pioneering capacitive sensors and provide precise positional feedback in closed loop applications, Queensgate developed its NPC-D-5200 digital controller. The controller incorporates a precision capacitive measurement circuit that is updated with the stage position 120,000 times per second. This allows it to deliver high positional accuracy at speed. The controller/sensor […]

Measuring at the Nanoscale
Sometimes measurements have to be made at the smallest levels. Queensgate’s NX NanoSensor has the sensitivity to measure changes in position to an atomic scale. Key applications include: stage feedback, vibration measurement, metrology, deformation measurements, precision manufacturing, drift measurement, precision beam steering and microscopy. The non-contact position measuring system consists of two sensor plates – […]
