The MRA air/electronic column from Stotz USA eliminates the need for a PC in combining measurements and SPC (statistical process control) data, thereby resulting in a lower overall system cost for the user. Incorporating air gauging and electronic gauging into a simple design, the column is designed specifically for use on high-production, tight-tolerance parts. According to the manufacturer, the MRA integrates more measurements and more SPC data than any other system available without a PC add-on. The device features an easy-to-read 12-in touch screen where the actual part can be displayed with all relevant points of measurement shown on-screen. Programming to the column is done using either the touch screen or remotely with computer software. There are four bays in the front of the column that allow either electronic (LVDT-half bridge) cards or air-electronic cards to be inserted. Each card can host four simultaneous measurements.
