When the current sensor fails, the following situations may occur:

1. No or wrong output signal: A faulty current sensor may not produce a correct output signal, or may have no output signal at all. This results in an inability to accurately measure or monitor current values.

2. Unstable output signal: A faulty current sensor may cause fluctuations or jitter in the output signal. This will lead to errors in accurate current measurements.

3. Incorrect current measurements: A faulty current sensor may provide incorrect current measurements. This may be caused by damaged components within the sensor or a failed calibration.

4. Short circuit or open circuit: A faulty current sensor may cause a short circuit or open circuit in the sensor's circuit. This will cause the current measurement system to not work properly.

5. Overload protection triggering: Some current sensor designs may include overload protection features. When a current sensor exceeds its rated measurement range, it may trigger a protection mechanism that stops outputting a signal.

When a current sensor fails, it may result in an inability to accurately measure the current, errors or erroneous measurement results, and may have an impact on the normal operation of the current measurement system. In the event of a failure, the sensor usually needs to be serviced or replaced to restore normal operation.

Laser welding is a welding method that uses a high-energy-density laser beam as a heat source, that is, laser radiation heats the surface of the workpiece, and the surface heat diffuses into the interior through heat conduction to melt the workpiece and form a specific molten pool. The laser beam passes through the upper layer of light-transmitting material, and then is absorbed by the lower layer material, and the laser energy is absorbed and converted into heat energy, since the two layers of materials are pressed together. Thermal energy is conducted from the absorbing layer to the light-transmitting layer, causing the two layers of material to melt and bond.

It can be seen that the energy of the laser beam must be absorbed by the plastic to achieve a good welding effect, so the CO2 laser is generally used for plastic laser welding. Also, not all plastics can be welded with laser welding. Plastics can be divided into thermoset and thermoplastic. Among them, thermosetting plastics are not reproducible and cannot be welded, while thermoplastics will melt after reheating (you can use heating and cooling to make them reversible), which is a so-called physical change, so it has weldability.

Compared with other welding methods, laser welding has the characteristics of high speed and good effect. way to weld complex parts, such as plastics containing circuit boards. Industries such as automotive, medical, consumer electronics, and food are ideal application areas for laser welding.

1. Automotive industry

Plastic laser welding machines are widely used in the automotive industry, such as automatic door locks, engine sensors, cab racks, fuel nozzles, gear shift racks, etc. Some models have also used laser welding for taillights.

2. Medical field

Plastic laser welding machines can be used to manufacture liquid storage tanks, liquid filtering equipment, hose connectors, ostomy bags, hearing aids, implants, microfluidic devices for analysis, and more.

3. Packaging industry

For example, the packaging of advanced industrial products, using plastic film welding technology, can obtain plastic packaging with high processing speed, reliable seams and beautiful appearance. Laser welding connection of plastic outer packaging material. Plastic materials are thermoplastics and elastomers.

Laser welding plastics has the comprehensive advantages of low cost, no pollution, high speed, convenient processing, easy realization of precise numerical control, wide application range of raw materials, good bonding and manufacturability. The application of plastic laser welding will become more and more extensive, and the technology will become more and more mature. In order to meet the growing demand for transparent plastic products in the industrial, medical and scientific research markets, Nanjing Hecho Technology provides various customized High-energy Transmission Optical Fiber for the laser plastic welding industry, with high transmittance, good uniformity, and high-energy transmission. Advantages, widely praised by the market.

Arrayed fibers are a special type of fiber structure composed of multiple individual fiber bundles arranged together in an array. Each individual fiber bundle has its own transmission channel and can independently transmit optical signals.

Arrayed fibers play important roles in many applications:

Fiber Optic Sensing: Arrayed fibers can be used as building units for fiber optic sensors. By using multiple fiber bundles, it is possible to simultaneously monitor and measure physical quantities at multiple locations, such as temperature, strain, pressure, etc. Arrayed fiber sensors have the advantage of high sensitivity and multi-channel measurement.

Medical Field: Arrayed fibers find widespread use in medical imaging and diagnosis. They can be used to construct high-resolution fiber optic coherence tomography (OCT) systems and fiber optic microscopes for real-time observation and diagnosis of tissue and cellular structures.

Industrial and Scientific Applications: In industrial and scientific research fields, arrayed fibers can be used for applications such as spectroscopy analysis, laser processing, and optical measurements. Arrayed fibers with multiple channels can provide a larger sampling range and higher data processing capability.

What is biochemical analysis? 

Biochemical analysis refers to the detection method of enzymes, carbohydrates, lipids, protein and non-protein nitrogen, inorganic elements, liver function and other indicators in the body through various biochemical reactions. It is mainly used in routine testing in hospitals. 

Biochemical diagnosis developed earlier in my country and is a routine diagnostic testing item in hospitals, focusing on disease monitoring that has already occurred. 

At present, the domestic biochemical diagnostic reagent market is relatively mature, with a complete range of reagents. Domestic brands have occupied about two-thirds of the domestic biochemical diagnostic reagent market by virtue of the advantages of cost-effective products and high-quality market services. 

What is an immunoassay? 

Immunoassay is a highly selective diagnostic method established by using the specific reaction between the substance to be tested and its corresponding substance. It is often detected by the immune reaction of antigen and antibody, and various carriers are used to amplify the reaction signal to enhance the detection. Sensitivity (labels include isotopes, enzymes, chemiluminescence substances), including radioimmunity, enzyme-linked immunity,  chemiluminescence, etc., mainly to test small molecular proteins, hormones, fatty acids, drugs and other substances in the body, commonly used in infectious diseases, endocrine Detection of protein targets such as diseases, tumors, pregnancy tests, blood group antigens, etc. 

At present, high-end chemiluminescence has gradually replaced ELISA as the mainstream immunodiagnostic method in my country, focusing on the monitoring of infected diseases. 

ELISA: ELISA markers are enzymes, which are often used to detect an antigen or antibody. Reagents have the characteristics of low cost and large-scale operation, and are currently the mainstream of domestic immunodiagnostic reagents. 

Chemiluminescence: Chemiluminescence reagents have high sensitivity, strong specificity, and good reproducibility. They can be used for highly automated semi-quantitative and quantitative analysis, and have fast detection time and good reproducibility. It is one of the important development directions of immunological reagents.
