Position sensors achieve sub-nanometre resolution
PISeca single-electrode position sensors can determine distance, position and length values with sub-nanometre resolution. These capacitive sensors from Physik Instrumente (PI) perform non-contact measurements against any kind of electrically conductive target. PISeca D-510 sensor probes are available for measurement ranges of 20, 50 and 100um, electronically extendable up to 500um.
In combination with PISeca E-852 signal conditioner electronics, they offer a resolution to 0.2nm (
Capacitive position sensors have been used for many years by PI for its own highest-precision nanopositioning stages. PISeca single-electrode sensors are fundamentally very robust and have very high temperature stability. Ease of integration of PISeca sensors is ensured by standardised sensor probes and signal conditioner electronics with an LED bar gap indicator.
PI's products are available in the UK through Lambda Photometrics Ltd.
