1. Piezoresistive pressure sensor Resistive strain gauges are one of the main components of piezoresistive strain transducers. The working principle of metal resistance strain gauge is the phenomenon that the resistance value changes due to mechanical deformation due to the strain resistance adsorbed on the base material, which is commonly known as the resistance strain effect. ...

1. Discrete photodiode with color filter The traditional practice of sensing color is to combine three to four photodiodes on a single chip, with red, green, and blue color filters placed on the surface of the photodiode (usually two blue color filters are combined together to compensate for the ...

The photoelectric head of a photoelectric sensor is a precision device, and misalignment can seriously affect the measurement results. This usually happens when external forces interfere with it, such as when the sensor position is shifted due to excessive force during cable construction. At this point, the position of the photohead needs to be readjusted. How to adjust: ...
