Coherent sensors are used in robots to mimic tactile functions. Tactile sense is an important sensory function when humans directly contact the external environment. Developing tactile sensors that meet requirements is one of the key technologies in robot development. With the development of microelectronics and the emergence of various organic materials, a variety of development plans for tactile sensors have been proposed, but most are currently at the laboratory stage, with few reaching productization. Tactile sensors can be roughly classified by function into contact sensors, force-torque sensors, pressure sensors, and slip sensors. Valve Coherent sensor classification

The basic principle of multi-sensor information fusion technology is similar to the process of the human brain comprehensively processing information. It performs multi-level, multi-spatial information complementary and optimized combination processing of various sensors, ultimately producing a consistent interpretation of the observed environment. In this process, multi-source data must be fully utilized for reasonable allocation and use. 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 information obtained from each sensor. This not only utilizes the advantages of multiple sensors operating in coordination but also comprehensively processes data from other information sources to improve the intelligence of the entire sensor system. Pressure sensors are the most widely used type of sensor. Traditional pressure sensors are mainly mechanical structural devices, indicating pressure through the deformation of elastic elements. However, this structure is 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 characteristics. Especially with the development of MEMS technology, semiconductor sensors are moving towards miniaturization, with low power consumption and high reliability.

Coherent sensor installation precautions

1) Correct installation method: Verify the frequency response value of the pressure sensor under normal atmospheric pressure and standard temperature conditions using appropriate instruments. Verify the correctness of the pressure sensor code and the corresponding frequency response signal. 2) Determine the specific installation location: To determine the numbering and specific installation location of the pressure sensor, 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 1 additional sensor(s) 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.

Coherent 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 mainly used to complete closed-loop force control. When the control valve spool moves suddenly, a peak pressure several times the system working pressure will form within a very short time. In typical mobile machinery and industrial hydraulics, if such extreme operating 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 pressure sensors to achieve shock resistance: one is to replace 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, mainly targeting the safety management system of the air compressor itself. There are many sensor applications in the field of safety control. As a very common sensor, it is not surprising that pressure sensors are used in safety control systems. Applications in the safety control field are generally considered from the aspects of performance, price, and operational safety and convenience. Practice has proven that the effect of selecting pressure sensors is very good. Pressure sensors use machining technology of mechanical equipment to install some components and signal conditioners on a very 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 controls the pressure brought by the compressor to a certain extent. This serves as a certain protective measure and is also a very effective control system. After the compressor starts normally, if the pressure value does not reach the upper limit, the controller will open the intake port and adjust to make the equipment reach 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 system, cold runner system, and the mold cavity. They can measure the plastic pressure at a certain point from the nozzle of the injection molding machine to the mold cavity during the processes of injection, mold filling, pressure holding, 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, as sensor manufacturers, we 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 type of sensor to use should be selected according to the specific mining environment. 5) Application in compressors and air conditioning/refrigeration equipment: Pressure sensors are commonly used in air compressors and air conditioning/refrigeration equipment. Such sensor products have a compact form factor, are easy to install, and the pressure guide port generally adopts a specialized valve needle design.
