Friction coefficient testing machines We stay connected Intersectoral connections Testing of bolted connections and fastening components is a matter of course in many industries and accordingly regulated by standards and internal rules. Top international position TesT GmbH is known for its expertise in force and torque measurement and provides application-oriented testing machines for leading industries such as automotive, aerospace, electricity, construction and energy all over the world. Whether destructive testing of various materials or tests of components such as nuts and bolts, there is...

ion coefficient testing machines Sensor core Mechanical decoupling force / torque. Data capture via strain Detailed and highly accurate TesT's combined force/torque sensors are based on the strain gauge technology and allow, in the maxi- mum configuration, parallel measuring of up to four parameters of screws, nuts and various fasteners. Clamping force and overall torque are always meas- ured. In the versions with three and four channels, in addition the partial momenta are determined at the bearing face and in the thread. Here, an effect of the clamping force on the torque measurement is ruled...

Friction coefficient testing machines_ Over the years, the requirements in screw testing have steadily increased. Where initially tests were only used in the automotive sector for creat- nections, today in-process testing of HV and HR bolts in steel construction prevails. Last but not least the ongo- ing development of wind turbines and associated steel pillar structures will further increase the dimensions. To- day already provides systems At the other end, there are industries such as medical technology, micro- mechanics and horology which take the requirements to ever smaller di- mensions....

Friction coefficient testing machines Manual friction coefcient determination The combination of our sensors with the Te s T m e a s u r e m e n t electronic and a special rmware allows straightforward determination of friction coefcients. Here, by measuring the parameters of force and torque, the friction coefcient according to alternative standards is determined and shown directly. Mobile equipment for friction coefcient testing For efcient quality assurance, fast and exible testing options in varying loca- The device comprises two independent measurement channels with 24-bit A/D converter...
