For accurate static and dynamic torque measurement wherever static reaction torque is required to be measured. These torque sensors are non-rotating type and are fixed on one end while the torque is applied to the other.

IEICOS Reaction Torque Sensors measure the reaction torque of an assembly under test. These sensors have no rotating components and hence are used only when the torque sensor experiences no rotating torque. It can still be used to measure torque of rotating machinery in specific applications. They are particularly suited to production applications in which they become an integral part of the system. .

Application

IEICOS Reaction Torque Sensors are machined as one piece from a solid block. Torque is measured by restraining the case of the test device, and is sensed by strain gauges on torque-sensitive flexures within the structure. No bearings or moving parts are incorporated to cause friction or hysteresis so there is no loss of accuracy at the low end sensor’s range. Because there are no slip rings or brushes, the sensors may be used when there is no rotation or for applications at any speed, from zero to high as desired with necessary dynamometers or tools. In general, IEICOS Reaction Torque Sensors may be applied where connecting power cables or hydraulic lines do not interfere with reaction torque. However, in some cases where these lines are present, the errors they introduce can be calibrated out by special techniques.

The sensor is mounted between the device under test and its normal mount. The torque reacted on the test unit housing produces a slight twist (as low as 0.1o) in the sensor elements. This twist is converted to an electrical signal proportional to torque by means of strain gauges. Readings are not materially affected by bending moments or extraneous loads. The units may be used in any position. The four configurations are available as indicated in figure with one-side shaft, both-side shaft type, flanged type and hollow type.
