Magnetostriction Displacement sensor It is a very commonly used precision displacement measuring instrument, which has certain applications in many industrial fields, such as Displacement sensor The application in the process of oil level change detection. At present, the measurement of oil volume in oil tank mostly adopts manual climbing and measuring with ruler. It can be seen that this measurement method is not only labor intensive, but also has unsafe factors and can not guarantee the accuracy. Capacitive / diffused silicon pressure level gauge is used in some places. Due to the serious zero drift, large measurement deviation and poor long-term working stability of this kind of sensor, it is not welcomed by users. There are also some places to use isobaric membrane level gauge or mechanical float level gauge. However, due to the influence of temperature and air leakage, mechanical float level gauge often appears steel band stuck phenomenon, so it has not been widely used. If used magnetostrictive displacement sensor In addition to ensuring the safety of personnel, it can also ensure the accuracy of measurement.
magnetostrictive displacement sensor In the use of oil tanks, it has the following advantages:
1. Good safety: magnetostrictive displacement sensor High explosion-proof performance. It has flame-proof and intrinsically safe explosion-proof, safe to use, especially suitable for the measurement of chemical raw materials and flammable liquids. There is no need to open the tank cover during the measurement to avoid the insecurity of manual measurement.
2. First of all, it is difficult to determine the working accuracy of the pulse sensor by measuring the working time of the pulse sensor, which is better than that of the other pulse sensors.
3. Strong reliability: because the magnetostrictive displacement sensor works with waveguide principle, there is no mechanical movable part, so there is no friction and wear. The whole converter is enclosed in stainless steel tube and has no contact with measuring medium. The sensor works reliably and has a long service life.
4. The magnetostrictive displacement sensor is easy to install and maintain. The magnetostrictive liquid level meter is generally installed through the existing pipe orifice on the tank top, which is especially suitable for the installation of underground storage tanks and storage tanks that have been put into operation, and can not affect the normal production during the installation process. The most important point is to facilitate the automation of the system. The standard output signal of magnetostrictive displacement sensor is convenient for microcomputer to process the signal, easy to realize networking work and improve the automation degree of the whole measurement system.
Generally speaking, the applications of germanjet magnetostrictive displacement sensor mainly include petroleum, chemical raw material storage, industrial process, biochemical, pharmaceutical, food and beverage, tank farm management and underground storage of gas station, industrial measurement and control of liquid level of various liquid tanks, dam water level, reservoir water level monitoring and sewage treatment, etc
