Sensor - solar water heater control of the key instrument
Breaking decades problems Jinzhao
In recent years, with domestic coal, electricity, natural gas and other conventional energy crisis intensifies, solar water heaters, energy conservation advantages highlighted began its industry after 10 years of development, has also been gradually becoming more mature. Behind the brilliant prospects, production enterprises mixed, after-sales service not guaranteed, dealers limited strength, resulting in solar water heater users will be faced with all kinds of problems, such problems mainly come from the frequent failure of solar water heater.
This caused frequent failure was due mainly to the installation of solar water heaters, water tanks in the water level in water temperature sensor failure. Most of the current use of solar water heaters is the use of micro-sensors, separation principle, the use of silicone outer parcels or other materials, cost is relatively low. Solar sensors work very adverse environment, mainly placed in the water tank, and sooner or later change in the temperature difference compared keen, while statements on its surface easily scale to be between conductive electrodes, causing sensor failure, the overall control system paralyzed, and a large number of water the loss of or inability to use solar water heater.
SWH to really become useful, the problem must be broken sensor. The market used by the water level and water temperature sensor electrode - contact surface of the electrode, forming because of a sensor malfunction scale, the difficulty is how to solve the circuit will not happen electrical contact with the surface. Shandong Jinan days Fuyuan TRADE Limited under the leadership of chairman Liu Jianmin, together with other research institutions, as long as six years after the scientific experiments, the actual operation for three years, four years Chinese pilot, and finally within this industry as long as 10 years to solve the problem. Grand launch industry is not the only single-node Float-scale water level and water temperature sensors.
Jinan days Fuyuan company's single-floater-level temperature sensor through floater in the plus or minus water tank, driven pendulum a corresponding displacement, water tanks, through the displacement of transmission components for instrumentation into control signals. Float using special sensors PP materials, high resistance to corrosion, water pollution-free, to 130 ℃ environment normal use. Transmission components (circuit) used in the vast majority of Japanese imports components, and ensured the sensor signal stability and long-term use can be. And electrode sensors, space-Fu-Yuan Float-level temperature sensor completely overcome the sensor electrode all weaknesses, burglary solved at the end of the industry decades puzzling problems. The product, as赛-type test laboratory testing, as well as related experts identified, agreed that the sensor electrode sensor service life is six times. Coupled with the performance of Maria's "Happiness of" card series controller, solar water heaters, so that the whole of this organism stable, reliable and accurate operation, a fundamental resolution of the solar water system reliability problems.
Single floater in the development of sensor at the same time, days Fuyuan companies have also launched a development project for the solar collector control counter tops-engineering sensor, the sensor circuit components in the same water tank, without furring impact of long service life.
