The best assistant of Pepperl+Fuchs displacement sensor industrial production line

P+F Pepperl+Fuchs displacement sensor is mainly used in the intelligent control of analog quantity in the production line of automation equipment. Displacement is a quantity related to the movement of the object's position during the movement, and the range of displacement measurement methods is quite wide. okplazas.com supplies original Pepperl+Fuchs products in spot and futures, with a penalty of ten for fakes!

P+F Pepperl+Fuchs small displacements are usually detected by strain gauge, inductive, differential transformer, eddy current, and Hall sensors. Large displacements are usually measured by induction synchronizers, gratings, capacitive grids, magnetic grids and other sensing technologies. . Among them, the grating sensor has the advantages of easy realization of digitization, high accuracy (currently the highest resolution can reach nanometer level), strong anti-interference ability, no human reading error, convenient installation, reliable use, etc., and is used in machine tool processing, detection instrumentation and other industries. Has been increasingly widely used. The function of the displacement sensor is to convert the linear mechanical displacement into an electrical signal. In order to achieve this effect, the variable resistance slide rail is usually fixed on the fixed part of the sensor, and different resistance values are measured by the displacement of the slide on the slide rail. The sensor slide rail is connected to a steady-state DC voltage, allowing a small current of microamperes to flow, and the voltage between the slide and the starting end is proportional to the length of the slide. Using the sensor as a voltage divider can minimize the requirements for the accuracy of the total resistance of the slide rail, because the resistance change caused by the temperature change will not affect the measurement result.
