1/4 Inch Mounting Spacer
The 1/4 Inch Mounting Spacer is used when a sensor mounting stud or threaded sensor base is too long for proper back-to-back mounting on the AT-2040. The spacer adds clearance between the test sensor and reference sensor so the TUT and REF sensors can mate correctly without bottoming out on the threads.
The 1/4 Inch Mounting Spacer helps improve accelerometer mounting during back-to-back vibration calibration by adding clearance when a sensor thread is too long. It allows the test sensor and reference sensor to seat properly, helping maintain solid mechanical coupling and consistent vibration transfer during AT-2040 sensitivity testing.
