[dealer] Ankang single jet heat Table / well-being of single jet heat meter factory direct sales Keywords: the calorimeter flow sensor single stream of anti-jamming high temperature RF card 1 Introduction national heat metering reform undertakings being made great achievements, especially in recent years, growing energy shortages the case this year, for the control of the heating energy consumption, all levels of government, and even the whole society is unusually great importance, it is mass production, installation and heating the calorimeter season, for a variety of various models of heat table of the large demand is unprecedented, while increasing the performance and quality requirements of the calorimeter. 2, the current state of the industry analysis of a large number of popular domestic calorimeter is basically still a magnetic calorimeter, the so-called magnetic calorimeter, is on the acquisition of a traffic signal, the choice is a magnetic sensor, such as "Wiegand" ", Hall" "reed switch" and so on. Impeller on the application of this sensor calorimeter must install a magnetic ring, then it is easy to produce the following question: A. impeller magnets of the water, a lot of iron filings, rust, and the formation of the accumulation. Thus hindering the rotation of the impeller, especially after the heating is stopped, the amount of impurities will harden or cure, so that the impeller can not rotate, or very slow heating in the second year, and thus greatly reduce the accuracy of the flowmeter. B. demagnetization due to the hot water of the magnet, so after a long time working in the hot water, the magnetic force of the magnetic ring will gradually diminish, so that the coupling between the rotation of the impeller and gear and force decline, caused by rotation is not synchronized, so that The precision will gradually decline. C. Reed pipe: for reed pipe principle calorimeter for traffic signal by the reed switch to mechanical signals into electrical signals. It is easy to see that the work with the reed switch reed bent and relax, the working life and reliability of the reed switch is very worrying. Another disadvantage is that prolonged time with the reed switch, the reed pipe reed elastic strength will change, so that the original adjustment with good magnetic strength reed switch pull strength will become inappropriate , that is, there will be water meter pointer when the revolution, the reed switch not pull or full pull. These problems can occur soon in Calorimeter put into use after 2-3 years,. All this will affect the flow measurement accuracy of the calorimeter. Even worse, a high magnetic reed switch can never pull, and can not be output pulse signal. D. magnetic field: the reed switch and Wiegand sensor method Calorimeter there is a fatal weakness is extremely susceptible to interference from external magnetic substances. Is when someone with a magnet near the calorimeter, the external magnetic field to interfere with the internal magnetic measurement components, so they can not work or slow down. This gave him the opportunity to give some bad attempt. In summary, this the magnetic calorimeter difficult the heating measurement need to adapt to the long-term, with the constantly updated the calorimeter industry development and technology, is bound to be out of the market. 3, transformation program 3.1 traffic sensors LCT-9723 Profile Shandong force chuangying core Integrated Circuit Co., Ltd. recently introduced single stream of traffic sensors LCT-9723, R & D and production of new products to solve the above problems, a micropower (5-6μA), high-precision, without impeller traverse up and down impact, high reliability, strong anti-interference ability, resistance to large temperature difference, and with very good RF card. 3.2 LCT-9723 basic principle LCT-9723 outwardly through the probe transmitting ultrasonic frequency electromagnetic waves encounter Case impeller installed on a single stream metal sheet occurs after the change of frequency, amplitude, phase angle, by these signals. , finishing the output amplitude stabilization square wave, the signal can be received directly by the microcontroller. As we all know, the calorimeter market has extremely large potential, the recent policy of the country is also promoting calorimeter market and industrialization. If you want to dig into the pot of gold at the calorimeter market high-quality products is undoubtedly the most important in the beginning of the article, please remind all planned or already in production magnetic calorimeter (Hall sensor allows the author sincerely or even the acquisition design) reed switch colleagues, this type of design has a fatal flaw: the well-being of the single-stream beam the calorimeter / Ankang single stream beam calorimeter factory direct) is hot water with a lot of impurities, especially metal impurities . These impurities will be adsorbed on the head by the result of mining the number of inaccurate. Generally about half a year's time, the entire table is in a state of paralysis. 2) there is poor anti-interference ability of this design! 3) there is the power consumption problem. For these lessons, I have the personal experience of the experience. The calorimeter jet technology is a necessary condition, only a single stream beam design, is the true sense of the calorimeter. Single-stream beam of the calorimeter, TI's TMS3723B is undoubtedly the world's most mature technology, the chip has a 5-year history of successful use in Germany. Process involved in the successful development of the TMS3723B jet traffic detection technology, the author summarizes the three difficulties, for your reference, if any shortcomings, the exhibitions! 1) machine table machine table throughout the calorimeter has a pivotal position in the design, had been ignored by our R & D team in addition to the high technology requirements of the machine table itself, the key: machine table contains a special impeller, the impeller blades coated the steam spraying process coating damping material, this material formulations can be said that industrial secrets, once hindered the progress of our research and development here, and later, we finally found it in a foreign country, offered to buy before they solved! the sealing cover the design, to be taken into account with the The combination of a circuit board, especially in the 3-position of the sensor distance, in the initial design must take into account. After nearly a year and a half, the efforts of the entire team, the machine table is ultimately successful development! Cikuan table body is designed for the use of a single-stream the beam flow detection technology, TMS3723B RF card water meter, heat meter developed, the whole process is according to the German standard do, the tightness of the table body, precision, stability, and magnetic resistance are the best, is also the first dedicated calorimeter meter body. This table body has passed a national testing and large-scale use. Tel 15,810,781,837 qq779243500 Contact Mr. Mao) TMS3723B traffic detection technology traffic detection technology control we also spent a lot of time to do the entire focus of the R & D team start on this on a summary of what is needed strong microcontroller development of the overall concept of the ability and heat meters into the return water temperature, liquid crystal display, data acquisition is difficult difficult language to express a very strong team, do not down Write software consuming 1. Test and modify it took about half a year's time. 3) the initial investment of the initial investment and the production process is relatively large, light a calorimeter testing equipment, imported more than a million, the domestic but also about five hundred thousand, and a set of testing equipment for the production of the calorimeter, indispensable production tool! I think, this investment for any business, not a small number. Production demanding, especially due to of each calorimeter machine table parameters are not the same, you need to write these parameters measured in real time program production (It can be said that each calorimeter software programs are not the same ), via the computer amendment so as to ensure the accuracy and stability of each heat meters. In summary, the calorimeter design and production is very complex and high-tech, has only a small amount of orders and plans while doing technical reserves, while looking for the market for the company, the entire human and material inputs is huge . So how to solve these difficulties? Technology transfer Although it is a method, but I also think that is not a best way. OEM Although an expedient measure, but undoubtedly the most appropriate solution.
