The important position of instrumentation in industry
The present situation and trend of partial discharge tester is an indispensable instrument in industrial production. China's vast territory, industrial types complete, so the level of the demand for instrumentation is very large. In the "XV" period, about 75,000 ~8.0 per year, this is a big market, competition is very fierce. Domestic level instrument manufacturers numerous, but mostly technical content is lower, lower prices of products, sales of many, but the value is not high. High-grade modern new instruments are mostly imported, especially for large enterprises with the level of instrumentation are basically imported instruments, even pressure or differential pressure level meter is also used in the radar level meters are imported or joint venture pressure or differential pressure transmitter. Therefore, the development, production high-grade advanced level instrument is still occupy the domestic level instrument market key. The following specific analysis of various types of level instruments market trends.
Brief analysis of present situation and trend of PD testerThe present situation and trend of partial discharge tester is a brief analysis of large and low value products, with liquid level switch and material level switch. At present, the leading product of the liquid level switch is the floating ball liquid level switch, the second is the tuning fork type and the capacitance type liquid level switch, this trend will not change much in the future for a long time. However, with the improvement of enterprise management level, not only the price of instrument itself is low, but also requires simple installation, high reliability and small quantity. Therefore, the RF admittance type (capacitive) and ultrasonic level switch market share will continue to increase. Because of the RF admittance type switch is simple to install, no movable parts, high reliability, small maintenance, and in the pressure and anti-corrosion is better than floating ball switch. Ultrasonic level switch belongs to non-contact measurement, its superiority is obvious, as its own manufacturing prices continue to reduce, will occupy a considerable share of the market.
Solid material level switch is mainly the main resistance, followed by the tuning fork and capacitance type. However, the low reliability is due to the spin-off position switch in the constant rotation. Therefore, the same reason, RF admittance and ultrasonic level switch market share will have a significant increase, especially the RF admittance level switch is the best measurement of solid materials at this stage of the optimal type.
Market trend of liquid level meterThe application of liquid level meter is very different, so there are various kinds. In the production process of various types of tower tank liquid level detection is still based on pressure and differential pressure transmitter. In addition to its own cost-effective and have some advantages, but also the design and application of the habit of problems. Next is the magnetic float type, buoy type, capacitance type liquid level meter also has the considerable application quantity. With the development of technology, the amount of magnetostrictive, ultrasonic and RF admittance level meter will increase rapidly, and the proportion of pressure (differential pressure) liquid level will decrease. According to the different medium and the field condition, each kind of liquid level meter each exhibition superiority, will form a pluralistic situation.
Tank area tank because of its large volume, requires a high precision liquid level, in the past, most of the use of the float steel belt level meter, servo-static pressure type also has a certain amount of application. However, whether the float steel belt, servo-type or static pressure level meter, is not the best way to measure tank tank level. The float steel belt type liquid level meter installs the complex, the reliability is also low, the hydrostatic level meter is affected by the medium density and the temperature very much, in order to eliminate these effects, a set of perfect static pressure measurement system is very expensive, the servo-type liquid level meter has high precision, but because of its mechanical transmission mechanism, it inevitably brings wear problems, and the price is also high. Since the 90 's, the radar level meter has entered the market, because of its high precision, high reliability, easy to use, so the dosage in the tank area increased rapidly, becoming the most preferred instrument in the tank area in the last ten years. In recent years, magnetostrictive liquid level meter has sprung up, because of its high-precision, high stability, high reliability and long life is more suitable for tank tank level measurement, the application volume will rapidly increase, and gradually and radar-type liquid level meter even. Optical fiber level meter can do on-site without electricity detection, security is good, this is its outstanding advantage, the disadvantage is still have a lot of mechanical transmission parts, failure rate will increase, installation is also more complex. Ultrasonic level meter precision slightly lower, but its simple installation price is moderate, therefore, will also have a place in the tank area.
