High IQ sensing——P+F Pepperl+Fuchs sensors are all in the sales base of okplazas.com

P+F Pepperl+Fuchs displacement sensor is widely used in petroleum, chemical, pharmaceutical, food, beverage and other industries to measure and control the liquid level of various liquid tanks. As a displacement sensor, it can not only measure the linear displacement of the moving object, but also give the speed analog signal of the moving object at the same time. The displacement sensor is also called a linear sensor, which is divided into an inductive displacement sensor, a capacitive displacement sensor, a photoelectric displacement sensor, an ultrasonic displacement sensor, and a Hall displacement sensor.

Generally speaking, an inductive displacement sensor is a linear device that belongs 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 this sensing surface, eddy currents are generated in the metal. The energy of the oscillator is absorbed, the output amplitude of the oscillator is attenuated linearly, and then the purpose of non-contact detection of the object is completed according to the change of the attenuation. The inductive displacement sensor has no sliding contacts, it is not affected by non-metallic factors such as dust when working, and has low power consumption and long life. It can be used under various harsh conditions. P+F Pepperl+Fuchs displacement sensor is mainly used in the intelligent control of analog quantity in the production line of automation equipment. The working principle of the magnetostrictive linear displacement sensor: When working, an initial pulse is generated by the electronic circuit in the electronic warehouse. When the initial pulse is transmitted in the waveguide wire, a rotating magnetic field is generated along the direction of the waveguide wire at the same time. When this magnetic field meets the permanent magnetic field in the magnetic ring or floating ball, a magnetostrictive effect is generated, which causes the waveguide wire to twist. This twist is sensed by the pickup mechanism installed in the electronic warehouse and converted into a corresponding current. Pulse, the time difference between the two pulses is calculated through the electronic circuit, and the measured displacement and liquid level can be accurately measured. It is used in displacement and liquid level measurement systems with high measurement accuracy and harsh environment.
