Even though mechanical torque wrenches have some slight disadvantages compared to digital wrenches, they are still widely used in production environments, said Crane Electronics.

JRS Opta's test benches speed up tool-testing
Crane Electronics has brought out a new line of JRS Opta (Joint Rate Simulator) computer-controlled test benches.
Torque system ensures correct tightening
An essential requirement of a torque control system was to recognise those engines which require additional tightening of an exhaust manifold before they are fitted to the vehicle.
Torque wrench is comfortable and communicates
An ergonomically comfortable torque wrench is claimed to offer most advanced measurement technology, storage and SPC capabilities currently available in tools of its type.
Crane Electronics, the market leader in torque control products, has devised a Torque Test Bench which enables manufacturers to test their mechanical wrenches and automatically document the results of these tests.
Removing the need to record the readings and calibrations on paper can lead to considerable savings in man hours during a shift.
The torque test bench is very simple to use.
It permits up to six stationary transducers to be mounted on it and can cover a torque range of 0.04Nm to 1695Nm.
To test a wrench, the adjustable wheel housing is moved along the bed of the test bench until the wrench handle sits on the cradle.
Torque is then applied manually via a gear box with the transducer being connected to a TorqueStar Opta.
This torque readout device indicates the results of the tests numerically on a display and as well as HI/OK/LO via LEDs.
The gearbox allows high torques to be applied but ensures that the operator does not exceed the rate of increase for the torque specified.
The design of the test bench also allows easy interchange between transducers.
The torque readings indicate whether a wrench falls within the torque limits or not.
If a wrench fails it can be recalibrated on the test bench to match the desired torque specification.
The torque readout digitally records all the readings and these can be downloaded to PC or the company's network.
Power tools can also be tested on the test bench with no additional costs.
Both the torque readout and torque transducer on the test bench are also suitable for testing continuous drive and impulse tools.
The only maintenance required for the torque test bench is to regularly clean the metalwork and the lead and plug assembly.
The stationary transducers contain no user serviceable parts. Request a free brochure from Crane Electronics ...
The recommended recalibration period for the stationary transducers is 12 months and Crane Electronics offers a full recalibration service to national and international standards.
