Quartz sensor for measuring a quasistatic or dynamic torque acting around the sensor axis. Thanks to very high rigidity, a high natural frequency of the measuring device is attained.
• Wide measuring range
• Captures even the slighest dynamic changes in a large torque
• High rigidity
The torque sensor consists of two steel disks, between which a ring is fitted which contains several shear-sensitive quartz plates. The crystal axes of the quartz plates are oriented tangentially to the peripheral direction and therefore yield a charge exactly proportional to the applied torque. The quartz set is protected by the tightly welded and rustproof steel case. The sensor is oil- and splashproof if a tightly fitted cable connector is used
The torque sensor is suitable for measuring a dynamic or quasistatic torque acting around the sensor axis.
• Adjusting torques of pneumatic screw-drivers
• Testing of screw connections
• Calibration measurements of manual torque wrenches
• Testing torsion of springs
• Measurements of friction clutches
• Measuring starting torques, variations in synchronization and torsional vibrations of fractional horsepower and stepping motors.
• Testing of rotary switch (product testing)
The torque sensor must be mounted under elastic preload with the tightening torque Ma as the torque must be transmitted by static friction onto the front parts of the sensor. Fig. 2 shows an example of preloading with a centered, elastic preloading bolt. When mounting the sensor, the mounting surfaces must be ground and the preloading bolt must be oriented perpendicular to these surfaces.
