With its compact, bearingless, maintenance-free design, the new TF Torque Flange Sensor from Magtrol brings many appealing advantages to torque measurement applications. The TF's high torsional rigidity supports direct mounting on the machine shaft or flange, avoiding the use of couplings on one side. This allows easy integration into a test system, shortens the overall length of the test bench and reduces costs.
Based on strain-gauge technology, the TF Sensor's precise telemetry system enables highly accurate signal transmission. A signal amplifier mounted in the measuring flange amplifies the measuring signal, modulates it to high frequency and transmits it inductively (via the HF transmitter) to the receiver. In the receiver, the digitized torque signal is transformed into an analog output signal of ±10 VDC. Rotational speed can be measured and converted to a TTL output signal with the optional speed pickup.

PCB® Series 5300D TORKDISC® In-line Rotary Torque Sensor Systems are designed for test applications requiring a robust rotary torque transducer where axial space is at a premium. Onboard, the transducer is a field proven electronic module that converts the torque signals into a high-speed digital representation. Once in digital form, this data is transmitted to a non-contacting pick-up loop, with no risk of noise or data corruption. A remote receiver unit converts the digital data to a high-level analog output voltage, and a serial digital output.
Series 5300D incorporates dual high level analog outputs, AC and DC coupled, providing both static and dynamic torque measurement capability that can be recorded separately and independently scaled; which is particularly beneficial when high DC levels are present or when low levels of AC content is of particular interest. Series 5300D also features industry leading DC bandwidth to 8500 Hz, resulting in increased dynamic response characteristics. The DC coupled output features an 8-pole low pass elliptical filter with user selectable frequencies for minimal roll off at each filter selection. A 2-pole Butterworth high pass filter with a wide range of user selectable cut off frequencies is included with the AC coupled output.

The digital TorqSense RWT330 and RWT340 Series use the latest and same non-contact TorqSense technology as used in the RWT310/320 Series in three different body sizes for torque ranges from 500mNm to 10,000Nm, with above 10,000Nm on request. The only difference for this Series is that it may be more appropriate for some applications to have the sensor unit separate from the electronics unit due to space and/or environmental limitations.

The strain-gauge torquemeter are used in order to measure directly the static couples of any kind of entity. They are usually produced with refined collectors sliding contacts: they can be used at a low speed for short periods. Some application are: - to test the engines, reducers, drives, etc. - output measure for any rotating machine.

Crane's stationary transducers are the quality choice for the testing of all continuous drive, impulse and hand torque tools in the workshop and production line-side environment.Stationary transducers are used off the production line in workshop or line-side test stations. Combined with joint kits that represent the production joint condition, the stationary transducers form an effective off line test for verification of assembly tool performance.

The technology for our 'TorqSense' RWT310/320 Series Torque Transducers is based on the patented technology of measuring the resonant frequency change of 'Surface Acoustic Wave' (SAW) devices in a non-contact manner when strain is applied to a shaft to which the SAWs are fixed. The applied torque causes a deformation of the quartz substrate of the SAW device, which in turn causes a change in its resonant frequency. Essentially the SAWs act as 'frequency dependent' strain gauges.
The frequency signal measuring the resonant frequency is coupled via a non-contact RF rotating couple from the shaft to a fixed pick-up and it is the analysis of the difference in resonant frequencies between the two SAW devices, with electronic processing and calibration, that gives a precise indication of the torque transmitted by the shaft. SAW devices have a high immunity to magnetic fields allowing their use in motors, for example, where other analog technologies are susceptible to electronic interference and are not suitable.
The use of this patented measurement technique results in a transducer being able to sense torque bi-directional, with fast mechanical and electrical responses. As the method is non-contact it has also complete freedom from brushes or complex electronics, which are often found in traditional torque measurement systems.

FUTEK Advanced Sensor Technologies Multi Axis Load Cell are designed to measure a multiple of forces and moments simultaneously with a single Load Cell.
Multi Axis Load Cells can accurately measure up to six components (3 forces and 3 moments) of load. For example, Independent strain gauge bridges are used to measure three directions of force: Longitude, Latitude, and Vertical, as well as, the moments about each force direction. Separate receptacles or cables are provided for each axis of measurement. A careful structural analysis has been done to isolate the forces and moments, which results in a reduction of cross-talk sensitivities.
All designs are one piece flexures, machined and gauged to give optimum output, stiffness and durability. For example, one of our more innovative designs, the Stick Shift/Gear Shift Knob Transducer offers a lightweight, robust feature comprised of Anodized Aluminum and weighing as little as 9 oz. Its special ergonomically designed cover contains anti-slip notches for proper handling coupled with less hand strain on the user.

It is often the case that torque in a rotating shaft can be measured with a stationary, reaction torque sensor at some point in the powertrain. This is due to the existence of an equal and opposite force (torque) necessary to hold the drive and driven equipment in place.
