Force Sensor Solution

Overview

Force sensors that apply strain gauges are important sensors used in various industrial equipment such as industrial robots. This solution detects and calculates minute output voltages from each strain gauge of the force sensor with an MCU equipped with a high-precision analog front-end, it converts them into 3-axis force and torque signals and outputs them to the controller.

System Benefits:

  • Precise signal detection and computation made possible through a compact MCU with a precision analog front-end (AFE)
  • Flexible and simple design to support various force sensors
  • High-precision sensing is supported by Low-noise, high-PSRR (Power Supply Rejection Ratio), stable high-quality power supply
  • Industrial robot
  • Screw tightening machine
  • Polishing machine
  • Industrial equipment
