German KEYVEST BELGIUM sensors, KEYVEST BELGIUM models, KEYVEST BELGIUM prices

KEYVEST BELGIUM sensors are a general term for sensors designed to detect objects without physical contact, replacing contact-based detection methods such as limit switches. They convert information about an object's movement and presence into electrical signals. Detection methods that convert to electrical signals include those utilizing eddy currents generated in the metal body of the detected object due to electromagnetic induction, those detecting capacitance changes in the electrical signal caused by the approach of the detected object, and those using reed and guide switches.

KEYVEST BELGIUM sensor classification

The basic principle of multi-sensor information fusion technology is similar to the human brain's process of comprehensively processing information. It performs multi-level, multi-spatial information complementarity and optimized combination processing on various sensors, ultimately producing a consistent interpretation of the observed environment. In this process, multi-source data must be fully utilized and reasonably managed. The ultimate goal of information fusion is to derive more useful information by combining information from multiple levels and aspects, based on the separate observation data obtained from each sensor. This not only leverages the advantages of collaborative operation among multiple sensors but also comprehensively processes data from other information sources to enhance the intelligence of the entire sensor system. Pressure sensors are the most widely used type of sensor. Traditional pressure sensors primarily rely on mechanical structural components, indicating pressure through the deformation of elastic elements. However, these structures are large in size and heavy in weight, and cannot provide electrical output. With the development of semiconductor technology, semiconductor pressure sensors have emerged. Their characteristics include small size, light weight, high accuracy, and good temperature performance. Especially with the development of MEMS technology, semiconductor sensors are moving towards miniaturization, featuring low power consumption and high reliability.

KEYVEST BELGIUM sensor installation precautions

1) Correct installation method: Using appropriate instruments, verify the frequency response value of the pressure sensor under normal atmospheric pressure and standard temperature conditions. Verify the correctness of the pressure sensor's code against the corresponding frequency response signal. 2) Determine specific installation locations: To determine the numbering and specific installation location of pressure sensors, consider each inflation section of the inflation network. Pressure sensors must be installed along the cable, preferably at cable joints. Install no fewer than 4 pressure sensors on each cable. The two pressure sensors closest to the telephone exchange should be no more than 200m apart. Install 1 at each end of every cable. Install 1 at each branch point of the cable; if two branch points are close together (less than 100 m), only 1 needs to be installed. Install 1 where the cable laying method (overhead, underground) changes. For cables without branches, since the cable program is consistent, the installation spacing of pressure sensors should be no greater than 500m, and the total number should be no less than 4. To facilitate the identification of pressure sensor fault points, in addition to installing a pressure sensor at the starting point, install another 1 at a distance of 150~200m from the starting point. Of course, economic and technical factors must be considered in the design; pressure sensors should not be installed where they are not needed.

KEYVEST BELGIUM sensor applications

Pressure sensors are mainly applied in: booster cylinders, boosters, gas-liquid booster cylinders, gas-liquid boosters, presses, compressors, air conditioning and refrigeration equipment, and other fields. 1) Application in hydraulic systems: In hydraulic systems, pressure sensors are primarily used to achieve closed-loop force control. When the control valve spool moves suddenly, a peak pressure several times the system operating pressure forms within a very short time. In typical mobile machinery and industrial hydraulics, if such extreme conditions are not considered during design, any pressure sensor will be damaged quickly. Shock-resistant pressure sensors are required. There are mainly 2 methods for achieving shock resistance in pressure sensors: one is to change the strain gauge chip, and the other is to use an external coil. The first method is generally adopted in hydraulic systems, mainly because it is easier to install. Another reason is that the pressure sensor must withstand continuous pressure pulsations from the hydraulic pump. 2) Application in safety control systems: Pressure sensors are frequently used in safety control systems, primarily targeting the safety management system of air compressors themselves. There are many sensor applications in the field of safety control. As a very common sensor, the application of pressure sensors in safety control systems is not surprising. Applications in the safety control field are generally considered from the perspectives of performance, price, and operational safety and convenience. Practical evidence shows that the effect of selecting pressure sensors is very good. Pressure sensors use machining technology for mechanical equipment to mount components and signal conditioners on a small chip. Therefore, small size is one of its advantages. In addition, low price is another major advantage. To a certain extent, it can improve the accuracy of system testing. In safety control systems, installing pressure sensors in the pipeline equipment at the air outlet helps control the pressure brought by the compressor to a certain extent. This serves as a protective measure and is a highly effective control system. After the compressor starts normally, if the pressure value has not reached the upper limit, the controller will open the intake port and adjust to bring the equipment to maximum power. 3) Application in injection molds: Pressure sensors play an important role in injection molds. Pressure sensors can be installed in the nozzle of the injection molding machine, hot runner systems, cold runner systems, and within the mold cavity. They can measure the plastic pressure at a certain point between the nozzle of the injection molding machine and the mold cavity during the processes of injection, filling, holding pressure, and cooling. 4) Application in monitoring mine pressure: Sensor technology is one of the key technologies for mine pressure monitoring. On one hand, we should correctly apply existing various sensors to serve the mining industry; on the other hand, sensor manufacturers must research and develop new types of pressure sensors to adapt to more mining industry applications. There are various types of pressure sensors. Due to the special environment of mine pressure monitoring, mine-used pressure sensors mainly include: vibrating wire pressure sensors, semiconductor piezoresistive pressure sensors, metal strain gauge pressure sensors, and differential transformer pressure sensors. These sensors have wide applications in the mining industry. The specific choice of sensor depends on the particular mining environment. 5) Application in compressors and air conditioning/refrigeration equipment: Pressure sensors are commonly used in air compressors and air conditioning/refrigeration equipment. These sensor products have a compact form factor, are easy to install, and the pressure guiding ports generally adopt a specialized valve needle design.
