Aging test in the production process of radar level gauge

 

With the rapid development of electronic products, the requirements of electronic products in terms of integration performance and technology are becoming higher and higher, and the requirements for the quality of electronic products and testing methods are becoming more and more strict.

 

 

As the most advanced process instrument in the industry, radar level gauge is widely used in various fields. In order to ensure that it can be used normally in different environmental climates, it will not affect the normal use of products due to different environmental climates and cause abnormal quality. Our company has conducted very strict aging tests for each radar level gauge to ensure the quality. 


Today let us reveal how many times a radar level gauge needs to be inspected during the production process.


First, High and low temperature aging test for the electronic circuit boards


In terms of equipment, the HYQ-TH-225DH constant temperature and humidity test chamber is used to conduct high and low temperature aging tests on electronic circuit boards. We make real-time monitoring of products during the aging process through self-made working devices and external display screens.

Aging test in the production process of radar level gauge

The aging test requires that each electronic chip needs to be subjected to high and low temperature aging tests. Energize the whole process during aging, with a temperature range of -40 ℃ to + 80 ℃ as one cycle, a total of three cycles. During the aging process, power on and off from time to time to check the product performance indicators.

Second, The Electronic unit of radar level transmitter aging for 72hours

After the high and low temperature aging test, then enters the second step of aging: 72 hours of normal temperature aging of the electronic unit.

The Last, Aging test of the whole radar level sensor

Xi'an Dechuang is responsible for each radar level sensor. After the assembly of each radar level transmitter, it will conduct a 72-hour normal temperature aging test again. To ensure the reliability of its measurement.

    Instrument knowledge|Radar level meter, how to reduce the interference in the tank on the measurement When we install the radar level meter, we will encounter many on-site storage tanks with supports, such as beams and brackets,etc . . . These supports will interfere with the signal of the radar level meter. If the above interference objects appear in the radar emission area, when the normal liquid level is below the interference objects, it will inevitably affect the normal measurement of the radar level meter, and false echo signals will appear. When encountering such situations, there are the following solutions: Method 1: Cleaning up on-site interferenceIf the interference is too large, completely occludes or most of the transmission signal of the radar level meter,...

    When selecting the type of radar level gauge, consider the influence of stirring and vacuuming, and pay attention to the power supply and output signal.1. Selection under stirringIn a tank with stirring, guided wave radar is generally not used. The force of stirring can easily bring the cable of the guided wave radar into the propeller, or bend the rod of the guided wave radar. Therefore, only high-frequency or low-frequency horn radar for non-contact measurement can be selected.If the lowest liquid level on site is above the stirring propeller, it generally has no effect on the measurement. If the minimum liquid level will be lower than the stirring propeller, it is necessary to filter out the signal reflected by the propeller by learning the function of false echo, so as to ensure that t...

    Intelligent radar water level meter helps carry out flood prevention workRecently, as tropical disturbances in the southern coastal areas of my country have developed into tropical depressions, heavy rainfall has appeared in many areas of southern my country, and the flood control warning has been sounded. Since my country entered the flood season, a new round of flood control and early warning work has once again been put on the agenda. In flood warning work, the status of monitoring instruments can hardly be shaken. In order to do a good job in flood control and early warning, and prevent problems as much as possible, the intelligent radar water level meter DCRD1000A2 researched and developed by Xi'an Dechuang Electrictrical Technology Co., Ltd. not only greatly improves the measurem...

    Why choose the radar level sensor in industrial process level instruments? The radar level sensor can measure the level that many other level instruments cannot measure, radar level sensor uses the microwave pulse measurement method and can work normally within the specified frequency range. It can be used in environments where inert gases and volatilization exist under the interference of temperature or pressure changes. The radar level sensor is a non-contact continuous measurement type process level instruments, which can be used to measure the level of liquids or solids, particle sizes and particulate materials. It corresponds to 4-20mA output, which is set by inputting the empty tank height E (=zero point), the full tank height F (=full scale) a...
