A device used for gauging the torque on an object by converting the strain applied as a mechanical motion into an electronic signal. Any change in Capacitance, inductance, or resistance is proportional to the strain.
You can increase the sensitivity of a force sensor using a strain gauge by either increasing the gauge factor (by using materials with higher sensitivity to strain) or by increasing the strain applied to the gauge (by increasing the length or width of the gauge). Both methods will increase the change in resistance of the strain gauge in response to applied force, resulting in higher sensitivity.
A strain gauge is a device used to measure mechanical strain, which is the deformation of an object under stress. It works by changing its electrical resistance in response to the strain applied to the object it is attached to. This change in resistance is then converted into a measurable electrical signal that can be used to determine the amount of strain the object is experiencing.
Factors affecting the accuracy of strain gauges include temperature fluctuations, mechanical stress on the gauge, incorrect mounting techniques, and electrical noise interference. These factors can lead to variations in the resistance of the strain gauge, impacting the accuracy of the strain measurement.
A strain gauge usually as a label on it indicating two things ,the range and so many mV/V output.If the range is 0 - 2 te and the mV/V is 1.5mV/V we then need to know the excitation voltage(V) of the instrument feeding the strain gauge.If the excitation voltage is 10 V then at the top end of the strain gauge (2te) the output of the strain gauge is 1.5mV X 10 =15mV.The mV output is indicated for it's range (2te) but is linear throughout the range therefor for half the range 1te the mV output is halved to 0.75 x 10 = 7.5mV.0te - 0mV0.5te - 3.75mV1te - 7.5mV1.5te - 11.25mV2te - 15mV
The strain gauge readings on opposite sides of a section will typically be opposite in sign, indicating that one side is under tension while the other side is under compression. This relationship is due to the strain being measured as a result of the material stretching or compressing when subjected to external forces.
Strain gauge lathe dynamometers are specialized devices used to measure the torque and power output of a lathe during machining operations. They work by incorporating strain gauges, which detect deformation or strain in a material when torque is applied, allowing for precise measurement of the forces in real-time. This information is essential for optimizing machining processes, ensuring tool performance, and enhancing overall efficiency in manufacturing. By monitoring the torque, operators can make informed adjustments to improve productivity and reduce wear on tools.
How I know if the strain gauge is gone
Advantages and disadvantages of strain gauge
"Mechanical Strain gauges" do not have inductance. There are many types of strain gauge: Mechanical, photoelastic, electrical etc.... Are you wanting the inductance of an electrical strain gauge? if so which type?
it is more sensitive small gauge size low hysteresis
