German ROGA INSTRUMENTS sensors, ROGA INSTRUMENTS models, ROGA INSTRUMENTS prices

ROGA INSTRUMENTS sensors are used to detect angles. The sensor body has a hole that fits LEGO axles. When connected to RCX, the angle sensor counts once for every 1/16 revolution of the axle. Rotating in one direction increases the count; reversing the direction decreases it. The count depends on the initial position of the angle sensor. When the angle sensor is initialized, its count is set to 0. If needed, you can reset it via programming.

ROGA INSTRUMENTS sensor classification

The basic principle of multi-sensor information fusion technology is similar to the human brain's process of comprehensively handling information. It performs multi-level, multi-spatial complementary and optimized combination processing of various sensors, ultimately producing a consistent interpretation of the observed environment. This process fully utilizes multi-source data for rational 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 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 mainly consist of 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. They are characterized by small size, light weight, high accuracy, and good temperature characteristics. Especially with the development of MEMS technology, semiconductor sensors are evolving toward miniaturization, featuring low power consumption and high reliability.

ROGA INSTRUMENTS 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 code against the corresponding frequency response signal. 2) Determine specific installation locations: To determine the numbering and specific installation positions of pressure sensors, consider each inflation section of the pneumatic network. Pressure sensors must be installed along the cable, preferably at cable joints. Install no fewer than 4 pressure sensors per cable. The two pressure sensors nearest to the telephone exchange must 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), install only 1. Install 1 where the cable laying method (overhead, underground) changes. For cables without branches, since the cable specifications are consistent, the installation spacing of pressure sensors should not exceed 500m, and the total number must be no less than 4. To facilitate identification of pressure sensor fault locations, in addition to installing a pressure sensor at the starting point, install 1 additional sensor(s) at a distance of 150~200m from the start. Of course, economic and technical factors must be considered in the design; do not install pressure sensors where they are not needed.

ROGA INSTRUMENTS 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, peak pressures several times the system operating pressure can form 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 2 main methods for achieving shock resistance in pressure sensors: one is replacing the strain gauge chip, and the other is using an external capillary tube. The first method is generally adopted in hydraulic systems, mainly due to ease of installation. 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 systems of air compressors themselves. Many sensors are applied 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 safety control are generally considered from the perspectives of performance, price, and operational safety and convenience. Practical experience proves that selecting pressure sensors yields very good results. Pressure sensors use machining technology for mechanical equipment to mount components and signal conditioners onto a small chip. Therefore, small size is one of its advantages. Additionally, low price is another major advantage. To some 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 generated by the compressor to some 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 certain points from the injection molding machine nozzle to the mold cavity during injection, filling, holding, and cooling processes. 4) Application in mine pressure monitoring: 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 are widely used in the mineral industry. The specific type of sensor to use should be selected based on 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. These sensor products are compact in shape and easy to install. The pressure port generally adopts a specialized valve needle design.
