It Takes 2 To Torque (Torque measurement)

THEY LAUGHED WHEN I SAID I WILL MEASURE TORQUE — BUT WHEN I STARTED TO MEASURE!
Torque measurement is a very common application, used to measure engine power output on propshafts and driveshafts, driver input through steering wheels, tightening bolts, or anywhere a component is subjected to a twisting force. The most common ways to do this are:
Single full bridge, 250US.
Our 250US gauge is often referred to as the “windmill” pattern. Designed for a one-step installation on large shafts or where access is restricted, it can be installed in minutes, requires only 5 solder connections, and is rugged and easy to handle without damage.
Dual-Shear (Grid) Pattern, 187UV.
This is a dual-grid, common-tab pattern, with 3 solder connections at one end of the gauge. Two of these are mounted diametrically opposite on a shaft and wired as a single full bridge. Somewhat more complicated to install, it will provide more accurate data in some situations. It’s important to know that the central common tab is for the signal output.

Do you have information about how your convert the strain signal to torque units? Whats the calculation?

La medición de la torsión es una aplicación muy común, utilizada, por ejemplo, para medir la potencia del motor en los ejes de la hélice y/o de la transmisión. Las formas más comunes de hacerlo son mediante el empleo de una banda extensométrica en configuración de Puente Completo del Puente de Wheatstone, modelo 250US; o bien con el modelo 187UV en montaje en medio puente, en cuyo caso se instalarían diametralmente opuestas dos de estas bandas, para obtener igualmente un Puente Completo.
