REVOLUTION OF VIBRATION SENSOR TESTING

Bestech Australia is introducing a new pod accelerometer modular mounting system from Meggitt.

It is such a simple idea that we found hard to believe nobody thought of it before, yet it will revolutionize vibration sensor testing.

The Endevco 46A general purpose accelerometer from Bestech, available in five sensitivities from 10 to 1000 mV/g, is threaded and can be fitted into a variety of different mounting blocks (or “pods”), with a stud or adhesive mount.

The pods offer test technicians the greatest possible flexibility. Whilst the hex and cube pods are designed to mount traditional single axis measurements, the tri-hex pod, with slots for three sensors, allows technicians to test up to three sensitivities at once – ideal if the customer is not sure what g-range is expected.

For multi-axis testing, the triaxial pod enables different sensitivities to be tested on different axes. The accelerometers can be removed and replaced, leaving the mount in place on the test object.

The innovative system will save money when the accelerometer has to be fixed permanently on to the test object. Only the mount itself has to be affixed. The more expensive accelerometer can be removed at the end of the test or swapped with an accelerometer of a different sensitivity.

The triaxial pod will provide substantial savings when a sensor on one axis breaks during testing – instead of replacing the whole unit only the broken sensor has to be replaced.

Testing shows the threaded accelerometer will not loosen from the pod, however the 46A and mounting bases have lock wire holes for customers that require them.

The accelerometer has a 10-32 microdot top connector, is eligible to bear the CE Mark and is IEEE P1451.4 TEDS capable. Pods are offered in anodized aluminum for applications where case isolation is needed and in titanium where case grounded measurements are required.

Endevco Model 46AXX POD accelerometer supplied by Bestech Australia is a general purpose accelerometer designed for versatility in mounting configuration. The POD mounts are available in five configurations – hex mount, cube mount, triax mount, tri-hex mount, and cube adhesive mount.

The POD accelerometer sensor assemblies may be mixed and matched in any of the POD mounts. The POD sensor assembly and mounting bases have lock wire holes to prevent the POD accelerometer from loosening during vibration for extra safety.

For users that do not know the correct accelerometer sensitivity for the test, the tri-hex mount is ideal.

The tri-hex mount allows the user to thread three different POD accelerometer sensor assemblies in a single mount.
