Low price full bridge strain gauge for sale, resistance of 350Ω or 1000Ω can be selected, and the sensitive grid is thin, which can better reflect the deformation of the surface of the component, thus the measurement accuracy is high.
Tips: How to choose the temperature self-compensation and elastic film self-compensation of the strain gauge?
According to the working temperature of the strain gauge and the material of the specimen, as well as the measurement accuracy requirements, the temperature self-compensating or elastic film self-compensating strain gauge working at this temperature is selected. For example, for ordinary steel or spring steel, a temperature self-compensating strain gauge with a linear expansion coefficient of 11X10^-6°C should be used; for aluminum alloy materials, a temperature self-compensating strain gauge with a linear expansion coefficient of 23X10^-6°C should be used. strain gauge.
