‘Smart washer’ enables touchless measurement of bolt axial load
Published: 21 February 2020 - Rachael Morling
New from JPB Système, the manufacturer of self-locking devices for the aerospace and aeronautical industry, is SMART WASHER, a disruptive sealing technology that enables touchless and wireless measurement of bolt axial load. As well as improving efficiencies within maintenance, repair and operation, this is expected to improve safety by providing more accurate measurements while reducing wear caused by the need to manually check each fastener is tightened sufficiently.
While performing the fundamental role of a standard washer, this uses intelligent connectivity to provide maintenance and service engineers with a clear picture of axial loads. This has been achieved through the use of a proprietary strain gauge as well as a transmission system into the washer which, via an accompanying app, combine to wirelessly relay information on smart devices such as tablets and smartphones.
Instead of having to manually check the torque level of every traditional bolt, in just a few seconds engineers can be quickly alerted to those specific fasteners that are either too tight or too loose.
The mobile app will ensure overall management by enabling the real-time monitoring and full traceability of each SMART WASHER unit, the company explains.
