New Protomar 300 In-Process Gauge For Cylindrical Grinders

The new Protomar 300 is an absolute gauge with measuring accuracies equal to that of standard in-process gauges.
The Protomar 300 gauge, which has a measuring range of 300 mm, has been designed for measuring diameters having continuous or interrupted surfaces of any shape and number of teeth with +/- 2 microns accuracy.
Its wide measuring range allows the Protomar 300 to gauge sequentially any number of different external diameters on large parts such as railway axles, mill rolls, printing rolls, electrical motors and wind power generators.
All measurements are referenced to a single calibration cycle, thereby eliminating the need for a dedicated setup master for each part or diameter to be ground.
