Page 4: Important Instructions
Important instructions: The model DRVL torque transducer can be deployed as a component in a test bench, for example. The installation position of the drive and transducer sides should be taken into account in applications where mass is critical. -
Page 5: Preliminaries
The torque transducers are made of different shaft materials to suit the loads. Torque transducers measure torque in the unit Nm. Please refer to the relevant data sheet for the current technical specifications. www.eth-messtechnik.de 2. Applicability and instructions for use The torque transducers measure clockwise and counterclockwise loads. In case of clockwise load, the output signal is positive. -
Page 6: Description And Functionality Of The Device
messtechnik gmbh 3. Description and functionality of the device 3.1 Torsional shaft The torsional shaft is constructed with special aluminum or hardened carbon steel to suit the full-scale value. Strain gauges attached to the torsional shaft sense the shaft torsion, which is proportional to the torque and is within its elastic range. -
Page 7: Disturbances And Their Compensation
messtechnik gmbh 3.4 Disturbances and their compensation Flexural, axial and radial forces are disturbances and, hence, should be avoided. We recommend the use of clamping hub couplings. They must be selected to suit the operating conditions. Shielded cables should be used for the electrical connections. The electroma- gnetic compatibility (EMC)of the torque transducers are tested for compliance with EN 55011:2011. -
Page 8: Conditions On Location
messtechnik gmbh 4. Conditions on location 4.1 Ambient temperature For best results, the device must be operated within the nominal temperature range. The best operating conditions are constant and, if necessary, slowly changing temperatures. The specified temperature errors apply if the tempera- ture does not change faster than 5K/h. -
Page 9: Mechanical Installation
messtechnik gmbh 5. Mechanical installation 5.1 Precautions to be taken when assembling the transducer • Handle the transducer carefully. • Do not overload the transducer, even temporarily when assembling the couplings, for instance. If possible before assembling the transducer, we recommend you connect it first electrically and monitor the torque with the analyzer. -
Page 10: The Measurement-Chain Setup
messtechnik gmbh 6. The measurement-chain setup A measurement chain is required for the transducer to take measurements. The measurement chain consists of: • a torque transducer • a connection cable • a power supply and display unit A power supply is required to supply the transducer with the necessary opera- ting voltage. -

Page 12: Wiring Instructions
messtechnik gmbh 7.1 Wiring instructions Electrical and magnetic fields often disturb the measurement circuit. These dis- turbances typically emanate from power lines running parallel to the test cables, but they can also come from nearby contactors or electric motors. Interference or noise voltages can be injected into the circuit as well electrically, especially if the measurement chain is grounded at many points. -
Page 13: Pin Assignment For The Connectors
messtechnik gmbh 7.3 Pin assignment for the connectors The pin assignments for the connectors are detailed on the following pages. The transducer outputs the measurements as an electrically isolated signal. The ground potentials should not be directly bridged at the transducer, as this could lead to incorrect measurements, depending on the length of the cable to the power supply and display unit. -
