![]() ![]() So lets take an example: suppose you put a strain of 500µε. Strain measurements rarely involve quantities larger than a few millistrain (fancy units for strain, but still very small). We set up a strain gauge load cell and measure that change in resistance and all is good, right? Not so fast. (The gauge factor for metallic strain gauges is typically around 2.) Small Changes in Strain If the resistance is below 2 Giga, then. Use a multi-meter to check insulation of wire leads to the metal body of the load cell. Remove the load and check if the mV/V output returns to the allowed tolerance. Load the load cell between 50 to 100 of its capacity for 5 seconds. ![]() The gauge factor is defined as the ratio of fractional change in electrical resistance to the fractional change in length (strain). Make sure it is within the allowed tolerance. Adjustable levelling feet / free floating feet allow you to level the. Cattle motion filtering software to lock onto weight. Standard overload capacity for chute, penning and shock loading. Gauge FactorĮach strain gauge has a different sensitivity to strain, which is expressed quantitatively as the gauge factor (GF). Heavy duty electronic weigh scales for single animal weighing. The most common strain gauge is made up of very fine wire, or foil, set up in a grid pattern in such a way that there is a linear change in electrical resistance when strain is applied in one specific direction, most commonly found with a base resistance of 120Ω, 350Ω, and 1,000Ω.
