P+F Pepperl+Fuchs Sensor Serves Industrial Control Industry 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. Among them, inductive displacement sensors are commonly used. A linear device belonging to metal induction. After the power is turned on, an alternating magnetic field will be generated on the sensing surface of the switch. When a metal object approaches the sensing surface, eddy currents are generated in the metal to absorb the energy of the oscillator and cause oscillation The output amplitude of the device attenuates linearly, and then the purpose of non-contact detection of objects is completed according to the change of the attenuation.

The working principle of P+F Pepperl+Fuchs displacement sensor magnetostrictive linear displacement sensor: When working, an initial pulse is generated by the electronic circuit in the electronic warehouse. When this initial pulse is transmitted in the waveguide wire, a wave along the waveguide wire is generated at the same time. The rotating magnetic field moving in the direction, when this magnetic field meets the permanent magnetic field in the magnetic ring or the floating ball, a magnetostrictive effect is generated, which causes the waveguide wire to twist. This twist is caused by the energy pickup mechanism installed in the electronic warehouse. Perceive and convert it into the corresponding current pulse, calculate the time difference between the two pulses through the electronic circuit, and then accurately measure the measured displacement and liquid level. It is used in displacement and liquid level measurement systems with high measurement accuracy and harsh environment. The analog type can be divided into two types: the physical type and the structure type. Commonly used displacement sensors are mostly analog structures, including potentiometer-type displacement sensors, inductive displacement sensors, self-aligning machines, capacitive displacement sensors, eddy current-type displacement sensors, Hall-type displacement sensors, etc. An important advantage of the digital displacement sensor is that it is convenient to send the signal directly into the computer system. This kind of sensor is developing rapidly, and its application is increasingly widespread.
