The displacement sensors in Pepperl+Fuchs sensors include potentiometer displacement sensors, inductive displacement sensors, self-aligning machines, capacitive displacement sensors, eddy current displacement sensors, Hall displacement sensors, etc. Send the signal directly into the computer system. This kind of sensor is developing rapidly and its application is becoming more and more extensive.

P+F ultrasonic sensor

When the Pepperl+Fuchs sensor displacement sensor is working, the electronic circuit in the electronic warehouse generates an initial pulse. When this initial pulse is transmitted in the waveguide wire, a rotating magnetic field is generated along the direction of the waveguide wire. When this magnetic field interacts with the magnetic ring or floating When the permanent magnetic field in the ball meets, it produces a magnetostrictive effect, 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, which is calculated by the electronic circuit The time difference between the two pulses can 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. Displacement sensors are mainly used in the intelligent control of analog quantities in automated equipment production lines. 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 attenuation.
