How is an excellent vibration level switch born?

All along, in all walks of life, product quality is the most concerned issue for people, and it is also a key factor in measuring product quality. To ensure product quality, product testing is an indispensable part, regardless of whether the product is simple or complex. In general, according to the different characteristics of the product, the quality characteristics of the product are summed up in seven aspects, namely product performance, reliability, life (or durability), maintainability, safety, adaptability, and economy. Because product testing can directly reflect the performance and reliability of products, in order to ensure the high performance and high reliability of products, it is of utmost importance to conduct strict inspections in accordance with the testing standards during production. For instruments belonging to precision instruments, Especially so. Because instrumentation is closely linked to the efficiency and safety of the factory, if there is even a slight problem in quality, the consequences will be unthinkable. This is why it is counted as the main reason why every product is not dared to be taken lightly. Well, today we have come together to see how an excellent vibrating level switch was born.

The vibration level switch includes four products: vibrating rod level switch, tuning fork level switch, tuning fork liquid level switch and compact tuning fork level switch (commonly known as small tuning fork). The vibrating rod level switch is the first in China. Dual-tube level switch has been favored by the market for its high reliability and cost-effectiveness.

Generally, in order to ensure product quality, the items that the vibration level switch must detect in the production process mainly include parameters such as frequency, amplitude, resonance state, appearance, sensitivity, and high and low position operation modes. Among them, the frequency, amplitude, resonance state and appearance of the product are the most important aspects of detection. In order to make it easier for everyone to better understand and realize the rigorous testing conducted at these inspection stages that are counted as automation to ensure the high quality of the product, the following interpretations of the four testing items are as follows:

First, frequency

The frequency is an important parameter of the vibration level switch. The detection of the material can be realized by detecting the change of the frequency and has high reliability.

During the production inspection process, the frequency of the same type of different vibrating level switch is allowed to fall within a certain range, but the vibration frequency of a single vibrating level switch is required to be fixed.

Second, the amplitude

Amplitude is an important index to measure the vibration level of a vibration level switch. Monitoring the change of amplitude can realize the monitoring of materials.

In the process of production inspection, it is counted that the production personnel must strictly control the amplitude within a certain range, neither too large nor too small.

Third, the resonance state

The state of resonance is a state with the strongest vibration, which is of great significance for realizing the detection of materials through vibration changes.

During the production inspection process, when the vibrating level switch is in a resonant state, the vibration energy can be concentrated on the probe without being transmitted to the rest of the connecting vibration body.

Fourth, appearance detection

The appearance inspection is mainly to detect the weld of the product and whether the surface of other parts has defects.

During the production inspection process, the production personnel must observe the instrument carefully with the help of a microscope, so all the appearance defects can be seen at a glance, and measures can be taken to eliminate the product defects in time so as to ensure the production of high-quality instruments.

Of course, in addition to these routine basic items, it is counted that in order to ensure product quality, third-party authoritative testing organizations are also required to test the product's performance. The inspection items include “IP66/67 protection level test” and “standard aluminum. "Alloy shell test", "Reliability test (Chinese and English version)", "National explosion-proof test", etc., counted as vibrating level switch All products have passed all kinds of stringent tests of the above items. High reliability provides assurance.

Shenzhen Jiwei Automation Technology Co., Ltd. in the level switch development and production, strictly in accordance with the testing standards and processes for production testing, effectively ensured the excellent vibration level switch of a Taiwan was born, making these levels Switch products have high quality and high reliability comparable to imported products.

Coin/Button Cell-retainers And Contacts

Antenk coin cell battery retainers Designed for memory back-up and stand-by applications, these contacts permit quick and easy coin cell replacement and installation. Eliminating "soldered-in" cells, computer, video, telecommunication and similar PCB based product users now have a reliable, "no tools required" method for changing batteries.

Extremely economical, these retainer contacts are available in surface mount (SMT) or thru hole mount (THM) styles for 4.8mm, 6.8mm, 11.6mm,12mm, 16mm, 20mm, 23mm and 24mm coin cells. The THM version has stable mounting legs for excellent board retention during wave solder. The SMT version includes a unique solder tail "flow-hole" design to bolster reflow and strengthen solder joints. They are manufactured from phosphor bronze, precision stamped and are plated with either a high luster nickel finish or matte tin finish ideal for low temperature soldering enviornments. Both feature dual spring contacts to assure reliable connections and a low contact resistance.

Antenk Coin/Button Cell-retainers And Contacts

Coin cell retainers are simple metal contacts that both electrically connect coin cells and hold them in place, while taking up minimal additional space on the PCB. They feature nickel-plating, and since most coin cells have nickel shells this helps to prevent galvanic corrosion, an electrochemical process that can damage dissimilar metals that are in electrical contact. Our retainers are always designed with automation in mind, and can be easily picked and placed, with both through hole and surface mount retainers available for most coin cell sizes. Combining the ease of automation with the low cost of Antenk's retainers, it is no wonder they are such a popular product.
