A resistive sensor is a device that converts physical quantities such as displacement, deformation, force, acceleration, humidity, temperature, etc. into resistance values. There are mainly resistance sensors such as strain gauges, piezoresistive sensors, thermistors, thermosensitive sensors, gas sensitive sensors, and humidity sensitive sensors.

Resistance strain gauge

The resistance strain gauge in the sensor has the strain effect of metal, which produces mechanical deformation under external force, resulting in a corresponding change in resistance value. There are mainly two types of resistance strain gauges: metal and semiconductor. Metal strain gauges can be divided into wire type, foil type, and thin film type. Semiconductor strain gauges have advantages such as high sensitivity (usually tens of times that of wire and foil) and small lateral effects.

piezoresistive

A piezoresistive sensor is a device made by diffusing resistance on a semiconductor substrate based on the piezoresistive effect of the semiconductor material. The substrate can be directly used as a measuring sensing element, and the diffusion resistance is connected in the form of a bridge inside the substrate. When the substrate is deformed by external force, the resistance values will change, and the bridge will produce corresponding unbalanced output.

The substrate (or membrane) materials used as piezoresistive sensors are mainly silicon wafers and germanium wafers. Silicon piezoresistive sensors made of silicon wafers as sensitive materials are increasingly being valued, especially solid-state piezoresistive sensors used for measuring pressure and velocity.

thermal resistor

Thermal resistance temperature measurement is based on the characteristic that the resistance value of metal conductors increases with temperature. Thermistors are mostly made of pure metal materials, with platinum and copper being the most commonly used. In addition, materials such as nickel, manganese, and rhodium have been used to manufacture thermistors.

Automation is the solution for our world and our goal.

With the courage to start a business, fearless pioneering spirit, and persistent innovative ideas, Walter Pepperl and Ludwig Fuchs, two founders of Beckhoff, jointly founded a radio repair shop in Mannheim in 1945. They rely on years of experience to generate innovative ideas and are always committed to technological innovation, developing new products for customers.

Years later, they invented a proximity switch, and these innovations marked the beginning of the glorious history of Beijiafu.

Nowadays, Beijiafu Company has become a world-renowned innovator in the fields of electrical explosion-proof and sensor technology.
