Torque Measuring Transducer Series 1
Torque Transducer Series 1
SERIES 1 -- Transducer Rating 10 / 32 / 50 / 100 (oz-in)
Vibrac's patented Optical Torque Transducers provide a precise method for accurate torque measurement. With over fifty years of successful field application, Vibrac Transducers have consistently proven their extreme durability and reliability.
The Transducers operate by shuttering light proportionally to the angular displacement of a torsion bar. This technique results in clean, noise free electrical output. The levels of these outputs are orders of magnitude greater than those of conventional transducers. By using precise encoder type discs, instead of brushes and slip rings, the Transducers are well known to have a
very long life and very low inertia.
Vibrac Transducers can be used for both dynamic and static torque measurement over a wide range of torque and speed. A 100% overload capability prevents permanent damage in accidental high-torque situations.
The Transducers used in conjunction with any of Vibrac s instrument packages are calibrated for zero and span with a single adjustment.

The Vibrac Mini Series Torque Transducers measure transmitted rotating torque or static torque with full-scale ranges as shown below:
The Vibrac Model 1312 DS Signal Conditioner Card and associated Torque Transducers offer a rapid and accurate means of evaluating many types of rotating devices. The torque transducer has been designed using carefully selected components to maintain the lowest inertia and friction load levels allowing for accurate torque measurements. This encoder interface and torque signal conditioner card has been designed to directly interface with all Vibrac Optical Torque Transducers (with optional encoders).
The torque signal conditioner card produces a DC voltage proportional to the torque applied to the torque transducer and provides for complete bias and calibration control. This module may be interfaced to control computers via DAC (digital to analog) and AtoD (analog to digital) devices.
To use this module, apply a DC voltage (Zeroing Signal In) to the card. Adjust this signal to produce a zero torque signal (Torque Output) while the torque transducer is in an unloaded condition. The analog torque output signal is a DC voltage that continuously represents sensed torque.
Once the transducer has been zeroed, a zero reference voltage is available to provide a monitoring point that the customer can utilize to return the transducer to the calibrated point without uncoupling the transducer from the loading or driving device.
