Ultra-high precision capacitive measurement sensor offering nanometer accuracy and stability. Interface with NI LabVIEW

The Accumeasure D series amplifier is a truly new revolutionary design that uses the latest technology to convert a highly reliable capacitive electric field measurement (displacement) directly into a highly precise 24 bit digital reading.

The standard feature quadrature encoder input, provides probe positional information simultaneously with its displacement signal. Capacitance displacement amplifiers used with quadrature encoders synchronize displacement measurements to the probe position to provide accurate surface profiles of various target types.
