RZ - 517 series magnetic float liquid level gauge is suitable for open or pressure container of liquid measurement. And it can achieve high sealing, leakage protection in high temperature and high pressure, high viscosity, strong corrosive conditions during the process of safe and reliable measurement of liquid level, can easily implement the real time observation, can be equipped with liquid level switch, to realize the liquid level in the lower limit alarm and control, also can equipped with liquid level sensor, realizing remote testing, record and control. Magnetic double column level gauge is working through the magnetic coupling effect, therefore the level once the phenomenon is the degaussing apparatus cannot be used properly, so why will appear this kind of phenomenon, can avoid and solve this kind of phenomenon is, we have to know about the below. Say first high temperature magnetic double column type level gauge of inspcetion degaussing. According to the company's experience inspcetion degaussing probably for several reasons: 1, hard magnetic material residual magnetism changes over time, influenced by its own factors with the passage of time, the residual magnetism coupled is less than the critical value; 2, using a temperature higher than Curie temperature of a hard magnetic material; 3, high performance hard magnetic material with hydrogen embrittlement phenomenon. Magnetic level gauge double column degaussing phenomenon its solution can be in the following aspects: * first, from the design point of view, should choose the appropriate hard magnetic materials. Such as the Curie temperature is higher than using temperature more than 20% and selected to ensure that five years later remanent magnetization (more than the critical value of magnetic materials Our company design and manufacture of magnetic level gauge requirements coupling double column critical value at about 1400 gauss) 。 Second, from the point of view of use, the user to do the following: 1, in use, to observe the conditions of the use of level gauge, Whether the normal service) , but also the actual temperature of the recording medium ( I have seen such a situation, the actual temperature tend to be higher than the temperature on the meter refs, design parameter table people may overlook certain factors) ; 2, when placing order, choose appropriate model to use magnetic double column temperature not to exceed the level of nominal temperature; Third, from the point of view of the production, processing and inspcetion should pay attention to the following: 1, within the inspcetion filling inert gas ( Such as argon) ; 2, welding ( Argon arc welding) When cooling measures needed to avoid inspcetion magnetic CaiLiaoChu temperature more than Curie temperature of a magnetic material. ( Instrument science and technology in this paper by embellish release, if you encounter any problems in the process of using the instrument, can call our domestic sales service hotline: 0517 - 86917118, we have * * personnel unriddling for you)
Guangdong Kaidi Energy Technology Co., Ltd. will continue to build a corporate culture that respects and values the unique strengths and cultural differences of our associates, customers and community.
Serving others for customers a better life with level gauge for employees respect and opportunity.
Guangdong Kaidi Energy Technology Co., Ltd. have significantly changed the way customers approach manufacturing. level gauge can still compete if we are willing to change the ways in producing.
