TensionPro has introduced a range of ultra low profile bolt load washers that is suitable for bolt load and tensioner tool calibration. Called TensionDisc, the washers are load sensors that monitor bolt loads in bolted joint assemblies.
A hand-held reader with a wired or infrared connection allows for reading of the bolt load. This data can be exported via USB to a PC. Optional connectivity options allow for multiple uses of the data. TensionDisc is available for bolt sizes M20 to M72 (and inch equivalents). Special designs are also available on request.
