Testing devices cerTEST-W for indicating torque and angle wrenches / 5413-53
The cerTEST-W testing devices are applied for fast and precise testing of indicating torque and angle indicating wrenches.
- Automatic testing of torque and angle wrenches
- Manual testing of torque and angle wrenches
The testing device consists of a mobile base unit with wrap-around casing, which holds the drive for the swiveling arm, the hybrid joint simulator, the electronic measurement and control system, a hydraulic unit and, on the mobile testing device, the accumulator. As an evaluation and operating unit, an optional rotating and tilting industrial PC system with a touchscreen and fold-out key-board or a notebook on an optional notebook mount is used. The torque wrenches to be tested are mounted horizontally with the exchangeable swiveling arm with sliding wrench support and coupled to the joint simulator via exchangeable square adapters as specified in DIN 3121. In order to meet the requirements for a test of the torque and angle wrenches influenced by the possible presence of an extension on the drive side, the joint simulation technology is vertically adjustable to include extensions as well. The joint simulator with built-in torque and angle sensors and the hydraulic brake system enable an exact simulation of the joint hardnesses required for testing to ensure compliance with standards. This allows torque wrenches to be tested consecutively in different joint simulations as often as required and the gathered data to be documented. The mobile testing device can be operated via a cord to the power grid, as well as line-independently via a built-in, re-chargeable battery. The stationary testing device is designed for grid operation.
