Measuring Load and Torque with Full Bridge Strain Gages.

The full-bridge circuit (with four active strain gages) provides for the highest measurement sensitivity and the best extraneous temperature cancellation. Built using Micro-Measurements' Advanced Sensors strain gage technology, the full Wheatstone bridge strain gages offer improved grid-resistance tolerance and grid-to-grid temperature matching compared to traditional gages. Micro-Measurements offers a wide range of pattern configurations and resistance ranging from 350 Ω to 20 kΩ. The addition of gold-plated solder pads improves lead wire attachment and solder-joint reliability, reducing the chances of solder pad oxidation prior to attaching the lead wires.
Compared to bonding multiple individual strain gages, the full-bridge devices provide simplified, more precise alignment and reduced bonding operations. All four active arms of the Wheatstone bridge circuit are formed on a single carrier, allowing the entire bridge to be bonded at one time. All intra-bridge connections are integrated into the pattern, thus eliminating intra-bridge soldering. Eliminating intra-bridge wiring and soldering helps to reduce zero TC problems. With no internal bridge wiring required, soldering is reduced to just four instrument wire connections, which greatly improves reliability.
In addition, with all four arms of the Wheatstone bridge being manufactured simultaneously from a single piece of foil, grid-to-grid thermal characteristics are more closely matched, and thermal output is cancelled in the bridge circuit. Micro-Measurements sensors are available in a variety of sizes, configurations, and mounting technologies.
Applications: Pressure transducers, Torque transducers, Automotive drive shafts and axles, Medical devices / force feedback, Infusion pump pressure measurement.

Could we measure the Tourque with strain guage using Labview and DAQ 6008?

If yes, please sent me a reference !
