Differential type high pressure air gauge interfaced to computer: A key instrument in mass production

Sanjay S. Lakade

Abstract

Air gauging is one of the important instruments used in metal working industry in mass production. Differential type-high pressure air gauge has wide range of applications in automobile industry. An effort was made to interface the differential type-high pressure air gauge to computer to facilitate the gauging. In our experimental setup LVDT is used to sense the displacement of the bellow and the amplified output of LVDT is given to the AD-DA card of the computer. This instrument can be used on critical machines to have data for continuous monitoring and statistical analysis of the process.
