German ASKA TRADE sensor, ASKA TRADE model, ASKA TRADE price

ASKA TRADE sensors are used to detect angles. There is a hole in the body that can accommodate a LEGO axle. When connected to RCX, the angle sensor counts once for every 1/16 revolution of the axle. When rotating in one direction, the count increases; when the direction of rotation changes, the count decreases. The count is related to the initial position of the angle sensor. When initializing the angle sensor, its count value is set to 0. If needed, you can reset it via programming.

ASKA TRADE sensor features

Currently, baffles can be designed according to the magnitude of water flow to reduce water resistance generated as water passes through the flow sensor, thereby reducing head loss in the water system. However, due to long-term impact from water flow, baffle-type sensors still suffer from fatigue issues; even if the flow value is calibrated at the factory, setpoint drift may occur. They are typically used in applications where precise protection of flow values is not required, i.e., for flow interruption protection against sudden stops in water flow within pipes. In China, very few are designed specifically for water-source heat pump units. The baffle type is specifically developed for water flow monitoring in water-loop/ground-source heat pump air conditioning units. It is equipped with different baffles for different pipe diameters, and the water resistance of each baffle does not exceed 0.5 meters of water column, which is significantly lower than that of target-type sensors. Each baffle-type flow sensor is equipped with pipe fittings identical to those of the water-loop heat pump unit's water pipes. On-site installation only requires connecting to the water pipe without any modification to the baffle. Additionally, the pressure rating of the baffle-type flow switch exceeds 25bar, making it a low-cost flow switch for water-loop heat pump units with less stringent water flow requirements. Feedback from use in water-loop/ground-source heat pump units indicates that differential pressure switches can effectively identify problems with on-site installed water piping in water-loop heat pump units, completely avoiding heat exchanger freeze-up caused by low water flow. Flow sensors can also protect against heat exchanger freeze-up due to reduced water flow caused by clogged water filters. Furthermore, water pipe differential pressure switches do not carry the risk of fatigue failure associated with target flow switches. Especially when there is a small amount of air in the water piping, flow sensors operate very stably without exhibiting floating behavior similar to target flow switches. Feedback from years of use has not revealed any faults in the differential pressure switch itself.

ASKA TRADE sensor principle

Basic principles and types of ultrasonic flowmeters: As ultrasound propagates through a flowing fluid, it carries information about the fluid's velocity. Therefore, by receiving the ultrasonic waves, the fluid velocity can be detected and converted into flow rate. Depending on the detection method, ultrasonic flowmeters can be classified into different types such as transit-time difference method, Doppler method, beam deflection method, noise method, and correlation method. Ultrasonic flowmeters are non-contact instruments that have come into application only in the last decade or so with the rapid development of integrated circuit technology. They are suitable for measuring fluids that are difficult to contact and observe, as well as large-diameter pipe flows. Linked with level gauges, they can measure flow in open channels. Using ultrasonic flow measurement means no measuring elements need to be installed in the fluid, so the fluid's flow state is not altered, no additional resistance is generated, and instrument installation and maintenance do not affect production pipeline operation, making it an ideal energy-saving flowmeter. Industrial flow measurement commonly faces difficulties in measuring large pipe diameters and high flow rates. This is because general flowmeters incur manufacturing and transportation difficulties, increased costs, and greater energy loss as the measurement pipe diameter increases. Ultrasonic flowmeters avoid these disadvantages. Since all types of ultrasonic flowmeters can be installed externally for non-contact flow measurement, the instrument cost is basically independent of the measured pipe diameter. In contrast, the cost of other types of flowmeters increases substantially with diameter. Therefore, the larger the diameter, the more superior the cost-performance ratio of ultrasonic flowmeters compared to other types with similar functions. They are considered excellent instruments for large-diameter flow measurement. Doppler method ultrasonic flowmeters can measure two-phase media flow, making them suitable for measuring dirty flows such as sewage and wastewater. In power plants.

ASKA TRADE sensor selection

When selecting flow sensors, users should choose suitable sensors based on their own needs. Many users have different requirements for the sensors they use, so the selected standards vary. If highly professional data and results are required, national standards should be selected. However, if the sensor is merely used as a simple instrument within an enterprise for rough analysis, enterprise standards can be selected. When purchasing flow sensors, careful consideration is essential, and one should choose sensors with guaranteed quality and good usability. Many people assume that new sensors inherently possess higher technology, which is a one-sided view. New products must feature mature technology to be considered good products. In many economic sectors, accurate flow measurement has become extremely important. Nowadays, sensors are basically used to measure flow quantities. Sensors sense fluid flow and convert it into usable output signals; installing sensors makes operation simpler and more convenient. The quantity of flowing objects passing through per unit time is called flow rate. Different flow sensors are used for different objects, and flow sensor types are often distinguished by the measured medium and measurement method. Flow sensors are generally used for the flow of media fluids in industrial pipelines. Under normal circumstances, there are various media such as gases, liquids, and steam. Several types of flow sensors can be universal for these various media types. The first type is the vortex flow sensor. Another type is the ultrasonic flow sensor. With the development of ultrasonic technology, ultrasonic flow sensors can generally measure the flow of most flowing objects. Ultrasonic flow sensors have various measurement methods, each with its own characteristics. We should select based on factors such as the properties of the measured fluid, velocity distribution, pipeline installation location, and accuracy requirements. Since industrial flow measurement commonly faces difficulties in measuring large pipe diameters and high flow rates—because general flow sensors incur manufacturing and transportation difficulties, increased costs, and greater energy loss as the measurement pipe diameter increases—ultrasonic flowmeters avoid these disadvantages. The flow measurement accuracy of ultrasonic flow sensors is hardly affected by parameters such as temperature, pressure, viscosity, and density of the measured fluid. They can also be made into non-contact and portable measuring instruments, thus solving flow measurement problems for strongly corrosive, non-conductive, radioactive, and flammable/explosive media that are difficult for other types of instruments to measure.
