Shimpo CAG-3000 Air Gauge


The Series CAG-3000 column type air gauge with micrometer display is a precision, non-contact measuring instrument when combined with a customized air probe sensor. Air gauge measurement has been around for decades. It is a non-destructive testing method that utilizes air flow and the resistance created between an object under test and the air gauge’s sensing probe. The air resistance or back pressure changes with distance between the air probe and device under test. This change in back pressure in the sensor can be scaled on a display to determine dimensional analysis as well as product acceptance.

The CAG-3000 Gauge Display with separate, customized air probe sensor performs fast, easy and precise dimensional analysis on components. Pass/Fail feedback is instant with the integral easy view three-color LED bar-graph display. Column displays can also be conveniently daisy-chained with additional units to allow quick inspections of multiple dimensions with various sensors. All CAG-3000’s come standard with RS-232 serial communications for data analysis on PLC’s. An Excel spreadsheet program is available for download for free from the SHIMPO website that allows communication with up to 5 units simultaneously.

The air gauge technology offers sufficient magnification and reliability to measure small tolerances down to 0.1 micron. Due to its fast response, outstanding tolerance and accurate repeatability, Tosok air gauge micrometers are ideal for quality measurements on the production floor.
