Portable gauge measures belt profile

First Quarter 2008 Other technologies

The BeltCheck TH 40 was designed to measure the wear and thickness profile across a conveyor belt, especially where the belt has embedded reinforcing steel cables. To accomplish this, the gauge has a sensor with an extra large diameter probe area to compensate for inconsistencies in magnetic substrate which occur due to differences in the steel cord mesh structure of the conveyor belts. Modern electronics compensate arithmetically for other inaccuracies produced by steel cords not positioned at regular intervals.

The BeltCheck can indirectly indicate whether the steel cords are still present. If they have rusted away, for example, they lose their magnetic properties and the gauge then has no magnetic substrate against which it can measure belt thickness.

The gauge can be used to not only measure the rubber thickness on steel cords at the edge of a conveyor belt, but also to take rubber thickness measurements across the entire width of a belt under inspection. So, unlike a conventional vernier gauge where measuring scope is limited to the edges of a belt, the BeltCheck can measure in the centre of the belt where the wear is greatest. The probe is connected to the gauge via a length of flexible cable for this purpose.

The onboard non-volatile memory facility allows the user to build up a usage profile in a spreadsheet application once a number of measurements have been taken.

The BeltCheck is a valuable tool for maintenance and can aid the user in avoiding costly cleaning-up expenses and lost man hours due to conveyor belt failure.
