STRAIN GAGE(GAUGE) FOR TORQUE MEASUREMENT on rotating components

Torsional force on round bars produces principal strains on the surface at 45 degrees to the axis of the bar. Dual element shear strain gages such as the Micro Measurements 187UV gages, bonded at diametrically opposite points on the bar will respond to these strains to give an output proportional to torque on the bar. A full bridge connection for the elements of the shear gages can be made on the bar, then lead wires can be taken to an instrument for measuring and recording the applied torque.
But if the bar is rotating , then wired connections between the gage and the instrument will be impossible. This video shows how a TECAT WISER telemetry system overcomes this problem , to measure and record the torque on the bar while it is rotating.

Hey. Thank you for the video. In the cylinder figure 1 and 4 are connected to P- but in the other figure, 1 and 4 are connected to P+ . Could you please explain?

[@balajir6047]

Sir, can you pls post a video or explain on how to setup the calibration test stand fixture setup for this shaft..?

[@TheRESMAT]

Sir what ADC use for sample rate per second for 500 hz in your circuit? Thanks

[@prashantgupta8914]

Sir can you make a video on how to measure stress induced in a circular hollow bar with help of strain gauge..

[@DynatecIndia]

If the hollow bar is not rotating, then you can bond a 3-element rectangular rosette gage to the surface, and measure the output of all the three elements of the gage individually. Orientation of the gage is not important. From the three readings, it is possible to calculate the principal strain and direction , and also the principal stress values.
I hope this answers your query

Hi sir i'm not from India but your video was helpfull

@@DynatecIndia sir where can I get a similar telemetry device? From Amazon preferentially

[@DynatecIndia]

@@josedavidcastilloblanco2437 The Telemetry System is made by Tecat Performance Systems in USA. They have an on-line store : tecatstore.com/
You can procure this system from there, or write to Don Keating, at [e-mail].

What are all the components (and their models) called please?

[@DynatecIndia]

These are rotating parts of machines. Examples are shafts, crank shafts, drive shafts, clutch, wheels of cars and bikes, bicycle pedals, helicopter blades, windmill turbine blades, aircraft engines, electric motors and generators, etc. Anything that rotates in any type of machine, and you have to measure the torque or strain on it, requires the use of a telemetry system like TECAT.
