New Precision Torque Tester
Mar 06 2015
New from Mecmesin, the Helixa precision torque tester has been designed for achieving precise alignment when using the most sensitive torque sensors. It is a significant development in the torque testing of finely engineered electronics components.
A choice of intelligent torque cells allows measurement from 6 N.m down to just a few mN.m. Concentricity at extreme low torques is ensured by the facility to align specific fixtures with the selected torque cell. Mecmesin’s Emperor™ control and acquisition software provides for building sophisticated test programs and complex results analysis. This combination of features ensures an unparalleled degree of accuracy and repeatability.
The Helixa is ideal where rotation of components is very precise, or very light, measuring a range of critical torque features in design and quality assurance. These include breakaway torque in rotary control components, the precise operation of click-stop switches, or the 360 degree smoothness of mass-produced trimmers and presets.
Where axial forces count, the Helixa has additional key features. A counterbalancing mechanism can be used to remove axial forces due to the torque cell and fixturing, and if required, a top-load platen can then be used to apply a specific static axial force.
Mecmesin Managing Director John Page stated: “With the release of the Helixa, Mecmesin now has the ability more effectively to address low torque applications (below 6 N.m) where the accuracy and repeatability of results is crucial. The counterbalanced crosshead means that the frictional effect on the sample from the mass of the transducer head during testing is significantly reduced.”
The Helixa is available as a PC-controlled version (the Helixa-i), driven by Mecmesin’s powerful Emperor™ software, or as a stand-alone version (the Helixa-xt) controlled from an integral touch-screen console.
Complementing the Helixa is a range of torque testing accessories, including a precision fixing plate for securing even the lightest samples and bellows for dust protection. Mecmesin has a team of experienced application engineers to design bespoke fixturing often required for precision testing at this level.
