Air Gauge Systems for Diameter Measurement

MERCER air gauging units and systems are mostly used for measuring cylindrical workpiece features such as bores and shafts. Non-contact air gauging offers many advantages, among others :
All the measurements are taken with high reliability and repeat ability is excellent since the sensors in the form of air plugs or air rings do not use any mechanical part for transmitting signals.
Non-contact measurement eliminates the risk of damaging the workpiece surface.
Air pressure acts as a powerful cleaner at the measuring points, thus enabling the user to inspect even dirty, oiled and greased surfaces or those exposed to solid contaminant, securely.
Linear displaying of a number of signals is highly accurate with up to 10'000x magnification.
