HIGH-PRECISION TORQUE SENSOR 8625  Measuring the static latching torque for plastic bearings


mounting plate safety couplings drive plastic bearing


torque sensor (is moved)


Benefits  Built-in instrumentation amplifier cuts susceptibility  End-mounting facility simplifies mechanical construction


Two precisely positioned plastic bearings are simultaneously fitted in a mounting plate by rotating through a fixed angle of 13 °. The friction torque and latching torque lie in the range of 4.7 Nm to 9 Nm. The 8625 torque sensor is used not only to detect the jump in torque as the part engages but also to measure the


friction torque needed while the part is running under the tab until it engages. The minimal linearity error allows tightly-toleranced monitoring of the distinct process stages. A safety coupling pro- tects against overloading the torque sensor.


 Non-rotating torsion measurement on elastic rubber dampers


controllable ball-screw


Highlights  USB port  TARE function


torque sensor (moves conjointly)


coupling rubber damper


Benefits  Good value sensor solution


Highlights  Linearity error 0.05 %  Analog output signal 0 … 10 VDC


The torsion and elasticity behaviour of rubber dampers is analy- zed in a test apparatus. The object under test is twisted through a small angle. The 8625 torque sensor, which is rotated conjointly, detects the anticlockwise and clockwise torque. The DigiVision PC


 Measuring the static torque on tank cap systems


tank cap motor


Highlights  Nominal temperature range –20 °C up to 80 °C  Flange-mounted model


Benefits  Extremely easy to fit


torque sensor


software reads the sensor measurements via the USB port on the basis of the set trigger criteria, then visualizes and documents this data.


The static torque needed to open and close safety tank cap systems on hazardous material containers (to overcome the catch/retaining force in both directions) is measured under various test criteria (level of soiling, number of open/close operations, gasket seating, etc.). The flange-mounted model of the 8625 torque sensor is very easy to fit in the particular application. The support for the object


under test and the weight exerted by the test object are decoupled from the measuring element. Temperature variations arising from ambient conditions and the nature of the hazardous material have only minimal impact on the measurement quality thanks to the wide nominal temperature range.
