Page 4: Introduction
INTRODUCTION The ETS Annular Torque Transducer comes with its own matching amplifier module and shares the same serial and model number. Transducers can be calibrated in either N∙m, lbf∙ft or lbf∙in as standard, but other units of Torque are available i.e. cN∙m, dN∙m, Kgf∙cm and Kgf∙m. The transducer torsion tube is made from heat treated stainless steel on to which are bonded strain gauges which are wired to form a Wheatstone bridge. -

AMPLIFIER AND TRANSDUCER CONNECTIONS Amplifier Pin 1: Constant current 20mA. input to amplifier. Pin 2: +10 volt supply. Pin 3: Amplifier output. Pin 4: Select decimal point output to ETS. Pin 5: 0v common, (Connected to Pin F of Transducer via Transducer lead). Pin 6: Input from Strain Gauge Bridge, (Connected to Pin A of Transducer via Transducer lead). -
Page 6: Amplifier Controls
Amplifier Controls The adjustments available are as follows: Fine Zero: To remove any temperature drift effect or non-zero reading. Coarse Zero: Used for initial bridge balancing, this potentiometer is covered by the label and should not need adjustment. Test: When the TEST switch on the ETS back panel is pushed and held in, the ETS display should read the full scale capacity to which the transducer has been calibrated. -

Page 10: Application Of Annular Transducers On Handtorque
APPLICATION OF ANNULAR TRANSDUCERS ON HANDTORQUE GEARBOXES To appreciate the operation of an Annular Transducer on a Handtorque gear box, users need to be aware of the following: TORQUE ON TRANSDUCER (T reaction) = OUTPUT SQUARE DRIVE TORQUE (T output) - INPUT TORQUE (T input) The reason for this is that the annular transducer measures the reaction torque, not the applied torque and part of the reaction torque is taken by the operator when the input to the multiplier is loaded... - Page 11 Tel + 61 (0)8 8292 9777 Tel + 86 21 6145 0368 Email enquiry@norbar.com.au Email sales@norbar.com.cn NORBAR TORQUE TOOLS INC NORBAR TORQUE TOOLS INDIA PVT.
