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.
This approach eliminates errors that used to be introduced by analog filtering, linearization, range extension and the summing of channels to obtain thickness or step measurements. The amplifier’s frequency response, and averaging are now all digitally controlled.
Many of our probes can operate at multiple ranges through digital range extension. Consult the probe brochure to determine the maximum range a probe may be extended. x1 and x2 range extensions are standard.
