Straingauge Type Transducer Introduction

A resistance strain sensor (straingauge type transducer) is a resistance sensor with a resistance strain gauge as a conversion element. The resistance strain sensor is composed of an elastic sensitive element, a resistance strain gauge, a compensation resistor and a shell, and can be designed into a variety of structural forms according to specific measurement requirements. The elastic sensitive element is deformed by the measured force and deforms the resistance strain gauge attached to it. The resistance strain gauge then converts the deformation into a change in resistance value, which can measure various physical quantities such as force, pressure, torque, displacement, acceleration, and temperature.
