Rotating Torque Sensor - By Lorenz

Supplier: Bestech Australia

The recently released Lorenz DR-2291 Rotating Torque Sensor features a quick change type 1/4 DIN 3126 (ISO 1173) coupling. This means you can use it with pneumatic and electric driven tools and assembly stations.

Price Guide: POA

The new Lorenz DR2291 slipring rotating torque transducer is available in ranges from ±1 to ±20Nm, its accuracy class is 0.1%, and the input impedance is 350? (nominal). Excitation or input is from 2 to 12Vdc (constant). The maximum operating speed is 2000rpm, and the electrical connection is via a 6 pole connector. A mating connector is included with the DR2291 torque transducer.
The DR2291 rotating torque transducer is located in series between a compressed air, or electric drive, and the device under test. A typical application is the measurement of the torque required to drive a fastener into a threaded bore or material.  In that example, a DIN 1/4HEX drive (male) shaft from the driver is pushed into the female DIN socket on the input end of the torque transducer shaft. The output end of the torque transducer plugs into the socket or blade driving the fastener being tested. The body of the DR2291 must be restricted from rotating in sympathy with the rotor by a strap or other means, and the drive is switched on. As the drive rotates, the DR2291 shaft senses the torque required to rotate the fastener. The output signal from the DR2291 changes accordingly.
Within the Lorenz product range is a wide range of signal conditioners which can be used with the DR2291. The signal conditioner provides an ultra stable excitation voltage for the torque transducer’s strain gauge bridge, as well as amplifying the output to a high level signal for external monitoring and/or control purposes. They include  0 - 10V or 4 - 20 mA. Microprocessor based controllers, as well as PC based systems, are also available for use with the DR2291 and all other torque and force transducers within the Lorenz product range. 
Bestech Australia provides complete information, application advice and back up support for the DR2291 and all Lorenz torque transducers, load cells and matching electronics.
