Web29 Oct 2024 · The maximum elongation of commercially available foil strain gauges is often specified as 2%. The k-factor is usually 2 to 2.2. This results in the following maximum resistance change for a 120 Ohm strain gauge: \Delta R_ {max}=2.2\cdot 0.02\cdot 120 = 5.28\; [\Omega] ΔRmax = 2.2⋅0.02 ⋅ 120 = 5.28 [Ω] In most cases, however, you work far ... WebFor this purpose, the shunt resistor is permanently inserted into the strain gauge bridge circuit, or alternatively into the connection terminals of the measuring amplifier. The parallel connection of a shunt resistor Rp to one of the four bridge resistors R results in a resistance change ΔR: ΔR = R · Rp / (R + Rp) - R (Gl. 1)
Webmany of the ways strain gages are used in bridge circuits and the equations which apply to them. Readers wishing a more thorough discussion of bridge circuit theory are invited to … WebThe AMP320 is a precision signal conditioner. It amplifies the low level signal (mV/V) of any strain gauge bridge transducer (pressure, force, torque, displacement) into a high level voltage (up to ±10Vdc) and/or current (4-20mA) signal. Operating from 14 to 26Vdc, it supplies the associated sensor with 5 or 10Vdc regulated power and enables ...
