German ZAKLAD HYDRAULIKI sensors, ZAKLAD HYDRAULIKI models, ZAKLAD HYDRAULIKI prices

ZAKLAD HYDRAULIKI sensors are sensors that use laser technology for measurement. They consist of a laser emitter, a laser detector, and a measurement circuit. Laser sensors are a new type of measuring instrument; their advantages include the ability to perform non-contact long-distance measurement, high speed, high precision, large measuring range, and strong resistance to optical and electrical interference.

ZAKLAD HYDRAULIKI sensor detection principle

This method detects impedance changes caused by eddy currents generated in the metal object being detected, by influencing it with an external magnetic field to detect magnetic losses caused by eddy currents on the conductor surface. An AC magnetic field is generated within the detection coil. In addition, other methods include aluminum detection sensors that detect frequency phase components, and all-metal sensors that detect only impedance change components through the working coil. A transformer state occurs on the surfaces of both the detected object side and the sensor side.

ZAKLAD HYDRAULIKI sensor classification

1) Capacitive proximity sensors: These are capacitive proximity switches with an electrode as the detection terminal. They consist of a high-frequency oscillation circuit, a detection circuit, an amplification circuit, a shaping circuit, and an output circuit. Normally, there is a certain capacitance between the detection electrode and ground, which becomes part of the oscillation circuit. When the object being detected approaches the detection electrode, the electrode, which is voltage-biased, undergoes polarization due to electrostatic induction. The closer the object gets to the detection electrode, the more induced charge accumulates on the electrode. Since the electrostatic capacitance of the detection electrode is C, the capacitance C of the detection electrode increases as the charge increases. Since the oscillation frequency of the oscillation circuit is inversely proportional to the capacitance, the oscillation weakens or even stops when the capacitance C increases. The two states of oscillation and non-oscillation are converted into switch signals by the detection circuit and output externally. 2) Inductive proximity sensors: These consist of a high-frequency oscillation circuit, a detection circuit, an amplification circuit, a shaping circuit, and an output circuit. The sensitive element for detection is the detection coil, which is part of the oscillation circuit. The oscillation frequency of the oscillation circuit is L. When AC current flows through the detection coil, an alternating magnetic field is generated around it. When a metal object approaches the detection coil, eddy currents are generated in the metal object, absorbing magnetic energy. This causes the inductance L of the detection coil to change, reducing the oscillation frequency of the circuit until oscillation stops. The two states of oscillation and non-oscillation are converted into switch signals by the monitoring circuit and output. Note: As with capacitive proximity sensors, the objects detected by inductive proximity sensors must be metallic conductors; non-metallic conductors cannot be measured using this method. Amplitude changes vary with the type of metal in the target object, so the detection distance also varies with the type of metal. 3) Photoelectric proximity sensors: The beam axis of the light-emitting diode (or semiconductor laser diode) and the axis of the phototransistor lie in the same plane and form a specific angle, intersecting at a point in front of the sensor. When the surface of the object being detected approaches the intersection point, the reflected light from the LED is received by the phototransistor, generating an electrical signal. When the object moves away from the intersection point, the reflection area falls outside the field of view of the phototransistor, and the detection circuit produces no output. Generally, the drive current supplied to the LED is not DC but an AC current of a specific frequency. Thus, the signal received by the receiving circuit is also an AC signal of the same frequency. Filtering the received signal to allow only signals of the same frequency to pass effectively prevents interference from other ambient light and can increase the luminous intensity of the LED.

ZAKLAD HYDRAULIKI sensor applications

Proximity sensors are mainly used to detect object displacement and are widely applied in aviation, aerospace technology, and industrial production. They are also used in daily life, such as in automatic doors and automatic hot air blowers in hotels, restaurants, and garages. For security and anti-theft purposes, important locations such as archives, accounting departments, financial institutions, museums, and vaults are typically equipped with anti-theft devices composed of various proximity switches. In measurement technology, they are used for length and position measurement; in control technology, they are used for the measurement and control of displacement, speed, and acceleration, where a large number of proximity switches are employed.
