German Dittmer sensors, Dittmer models, Dittmer prices

Dittmer sensors are used to detect angles. The sensor body features a hole compatible with LEGO axles. When connected to RCX, the angle sensor increments its count once for every 1/16 revolution of the axle. Rotation in one direction increases the count, while reversing the direction decreases it. The count depends on the initial position of the angle sensor. Upon initialization, the count value is set to 0; if required, you can reset it via programming.

Dittmer sensor classification

The basic principle of multi-sensor information fusion technology resembles the human brain's comprehensive information processing: it performs multi-level, multi-spatial complementary and optimized combination processing of data from various sensors, ultimately yielding a consistent interpretation of the observed environment. This process fully utilizes multi-source data for rational management and use. The ultimate goal of information fusion is to derive more useful information by combining information from multiple levels and aspects, based on discrete observational 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 structures, indicating pressure through the deformation of elastic elements. However, such structures are bulky and heavy, 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 favorable temperature characteristics. Particularly with the advancement of MEMS technology, semiconductor sensors are evolving toward miniaturization, offering low power consumption and high reliability.

Dittmer 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 spaced 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 at locations 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 not exceed 500m, and the total number must be no less than 4. To facilitate 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 start. Of course, economic and technical factors must be considered in the design; pressure sensors need not be installed where unnecessary.

Dittmer 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 primarily serve to complete closed-loop force control. When the control valve spool moves suddenly, peak pressures several times the system operating pressure can form within an extremely short time. In typical mobile machinery and industrial hydraulics, if such extreme conditions are not considered during design, any pressure sensor will quickly be damaged. Shock-resistant pressure sensors are required. There are mainly 2 methods to achieve shock resistance in pressure sensors: one is replacing the strain gauge chip, and the other is using an external coil pipe. 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 evidence shows that the effect of selecting pressure sensors is very good. Pressure sensors utilize 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 a certain extent, serving as a protective measure and 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 various points from the injection 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 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 feature compact forms and easy installation, with pressure ports generally adopting specialized valve needle designs.
