The Total Indicator Reading Module, Model Number AG-79-TIR-100, also known as T.I.R. Module is used in the Electron I Gauging Columns.
The T.I.R. Module is normally used for operations requiring concentricity or run out checks. The advantage of the T.I.R. Module is that it ignores fluctuations in size and thickness. In doing this the Module only concerns itself with the maximum and minimum value during a 360 degree sweep of the probe which results in a true T.I.R. reading. The column will visually display and hold the minimum and maximum readings during one complete revolution of the indicator.
Within minutes the T.I.R. module is easily inserted into the slot behind the removable cover plate of the Electron I Column. The unit provides a two light display consisting of a green light which indicates an In-Tolerance part and a red light which indicates an Out-of-Tolerance part. A Set Adjust potentiometer is used for setting the outer limits of the red light and a Zero Adjust potentiometer is used to position the visual indication at “0” on the column display by first depressing the “RESET” button.
When an out of tolerance condition is reached the T.I.R. Module is capable of activating a Control Module Output on the back of the column for external gage and machine control applications.
A "T.I.R./BYPASS" switch is available on the module so that the operator can switch back to the regular (BYPASS) mode allowing for initial probe positioning or tooling adjustments.
