• 【350 Ohm】 A resistive strain gauge sensor with a 350 ohm nominal resistance which varies when a force is applied. By measuring the change in the sensors resistance, a measurement of the force applied to it can be obtained.
  • 【Constantan Foil】The substrate is made of the modified phenolphthalein, and the grid is made of constantan foil.
  • 【High Precision】With high precision and good static measurement stability, the weighing sensor is suitable for 0.02 level sensor.
  • 【Mini Size】The 7.1*4.5mm specification makes it easy to dissipate heat, consumes less power per unit area, and is easy to paste and solder.
  • 【Temperature Compensation】Simultaneous temperature self-compensation and creep compensation.
