AccuTorque™ Sensor

The AccuTorque™ torque sensor provides a direct measurement of torque and thrust.  AccuTorque™ can be used to detect tool failures and to verify process quality.  Available in 3 versions, the AccuTorque™ sensor is incorporated into a rotating shaft, such as a spindle or tool holder, where it transmits the signal across a 5 mm air gap to a non-rotating stator.  Torque measurement is primarily used in rotating tooling applications where power monitoring is inadequate.  Applications may include drilling, tapping, or multi-spindle machines.  Thrust is used to detect a missing tool and determine that a process is performing as expected. 

The AccuTorque™ sensor provides a direct measurement of torque and thrust. Available in 3 versions, AccuTorque™ is incorporated into a spindle or tool holder where torque and thrust data about the rotating tool is transmitted wirelessly across a 5 mm air-gap. A non-rotating stator receives the data and transfers it to the control unit for processing. 

Torque measurements are primarily used in rotating tooling applications where power monitoring is inadequate. Applications may include tapping or machines with multi-spindle heads. AccuTorque™ is used to detect tool failures and verify process quality such as thread depth and hole size. 

Thrust is used to detect missing tools and determine that the process is performing as expected.

The AccuTorque™ sensor is supplied with a signal conditioning amplifier. This amplifier is sealed (IP67 rating), and can be placed within the machining environment. The amplifier is attached to the sensor using a 5 meter cable. Cables up to 30 meters long can connect the amplifier to the controller.
