Force measuring instrument VARIOcouple®

torqueelectromechanicallaboratory

The VARIOcouple® apparatus for torque and force measurement manufactured by CLA is a very precise instrument mainly used in development laboratories of watchmakers. This instrument allows quantifying and analyzing small torques and forces generated in low stress systems. ACCESSORYS : - Universal Digimes - Universal sample holder for watch movement - VARIOweight - Measurement standard - CLApt1000 - Temperature sensor - Adjustable angular support - Anti-vibration table Over the years, the VARIOcouple became the reference in force and torque analysis of low stress system. Used in both Research & Development laboratories and Quality Control, the VARIOcouple’s main applications are not anymore for watchmakers but also for stepper motors, rotary dynamometers, flowmeters, and the spring industry. Measurement principle The part to be measured is fixed on the central axis of the VARIOcouple by means of an intermediary support (grips, chucks, plate, mandrel, universal sample holder). A magnification camera, located in the measurement axis, then centers the object and prepares it for evaluation. The sensor is precisely positioned with the help of a micrometer displacement table consisting of three axes of freedom: X, Y and Z. Then, the sensor is precisely positioned with the help of a micrometer displacement table consisting of three axes of freedom : X, Y and Z. Measurement is carried out through an intermediary arm, needle or a pulley, which connects the axis to a force sensor, or to a torque sensor fitted coaxially to the test piece. A servomotor, providing speeds of 0.02 to 10 rpm or 60 rpm, drives this axis of the apparatus.
