UVAC versions of the Queensgate Series NanoSensors and our DPT-D and DPT-E ranges of Digital Piezo Actuators are widely used in Synchrotrons and Beamline applications.
The NX/NZ non-contact position measuring systems are based on the principle of capacitance micrometry with superior resolution and stability performance.
Two sensor plates (the target sensor and probe sensor) form a parallel plate capacitor driven at RF. The distance between these two plates can be measured to better than 0.1 nm resolution and with linearity of up to 0.02 % before electronic compensation.
They are available for ranges from 20 microns to 15 mm in a variety of materials including Aluminium, Super Invar and Gold on Zerodur for the most demanding applications.
The Digital Piezo Translators (DPT)
The DPT are a complete family of preloaded closed loop, piezoelectric actuators which are equipped with Queensgate non- contact, state-of-the-art capacitive sensors. This guarantees ultimate positioning performance.
Their super Invar construction provides high thermal stability and low drift.
The New DPT-D & -E series of of actuators offer up to 120μm displacement and 3,500 N blocking force with an exceptional repeatability of less than 0.5 nm.
The DPT-E range of actuators offer a low voltage size for size replacement for our existing DPT-C users.
