The general purpose strain gauge uses CuNi alloy foil of several microns. It is a general strain gauge which improved the operating temperature range by using a highly insulating plastic with a thickness of about 0.13 mm and high insulation. The gauge base is color coded separately for each temperature compensation target material. In addition to the general gauge, there are also special gauges such as concentrated stress measurement and torque measurement gauge. In addition, we have standard strain gauges with lead wires with vinyl lead wires. Installation of the gauge terminals and wiring are unnecessary, so the working time is shortened. Other combinations of lead wires dedicated to strain gauges are also available.
