Automotive products is a highly integrated final product, which is different from ordinary products, is built on a large socio-economic system project, the need for specialization, socialization, and the need for related industrial products Sensor and supporting. In recent years, the automotive consumer market in China's rapid expansion, so car manufacturers have to expand their production scale to adapt to this huge market.
Automobile production process point of view, in recent years, the domestic automobile manufacturing industry, a substantial increase in the level of automation, the obvious trend to improve the assembly accuracy and improve production efficiency. As a means of positioning and detection, a variety of sensors have been popular to all aspects of the production line, especially in the depot is widely used in positioning the inductive sensor, real-time monitoring of the entire line of running status. But the face of different manufacturers on the market, a series of sensors, how to choose the most suitable Fuel Rail Pressure Sensor for automotive applications in the field of products, become the key. For inductive sensors, we are not unfamiliar, is used for close positioning of metal objects in a common way. Because it is mainly through the Hall effect to complete the test, it is also known as the Hall sensor.
The internal structure is composed of two parts: the front end is composed of the core which is wound around the transmitting and receiving coil; the rear end is the circuit part, and the whole is encapsulated in the plastic or the metal shell. When working, the electromagnetic core part of the alternating magnetic field, the surface of the metal surface near the eddy current effect, thereby weakening Temperature Sensor the LC oscillation circuit, the amplifier circuit part of the analysis of the electromagnetic core receiver coil weak LC oscillation circuit changes, and give the corresponding output.
Different dimensions, the rated detection distance is generally up to 100mm. Under normal conditions, the manufacturers for its nominal detection distance in the laboratory conditions measured under the rated detection distance. Practical application, taking into account all aspects of environmental factors, the reliable detection distance of about 80% of the rated detection distance, but for the measured object is a certain requirement. Due to the application of the site of the measured material permeability and size, under normal circumstances can not meet the requirements of the standard measured object, then the sensor detection distance will be further attenuation, which is a lot of users feel the inductance sensor detection distance than the manufacturer Nominal little reason for a lot. In this case of non-standard testing, the manufacturers and their different series of products vary widely. In addition, there is a difference in terms of resistance to electromagnetic interference, ambient temperature, voltage disturbance, and installation requirements. Choosing the right sensor will greatly enhance the stability and reliability of the equipment operation and also maximize the possibility of reducing the sensor's failure or damage and reducing unnecessary maintenance inputs. Automobile manufacturing industry ABS Sensor in the production process, the extensive use of inductive sensors as positioning detection, how to choose the most suitable for this industry products, it is particularly important.
With the Chinese market demand for cars, as well as the improvement of vehicle performance requirements. Car manufacturers in the new project, its production line also has a higher standard. On the one hand, the need to meet the requirements of automotive manufacturing process; Moreover, the need to ensure the smooth and smooth operation of the entire line, to minimize maintenance and commissioning time to ensure Speed Sensor high production efficiency.
Car manufacturing links include four main parts: stamping, welding, painting, assembly. The inductive sensors are used in a large number of parts. Especially in the welding, painting and assembly shop, many of the inductive sensors distributed in the product chain conveyor line, play a crack detection or track in place detection.
Select this series of sensors mainly take into account two factors:
1. Far away from the detection range: Alice in the movement sometimes have a certain vibration, the sensor needs a certain detection distance to ensure that the measured part of the skew can not be due to vibration from the detection area or hit the sensor damage.
2. Moderate dimensions: In general, the detection distance and volume of the inductive sensor are proportional. For 40mm detection distance, 40 * 40mm detection side of the square shell size is very appropriate.
In addition to the selection of the main parameters, but also taking into account the more details to the site conditions and appropriate, so that the sensor and the scene environment, equipment, more matching.
First, the attenuation of the detection distance. Alice for the iron, suitable for inductive sensor detection; and skipping part of the measured size is slightly smaller than the standard size of the sample, then there will be some attenuation, the above models in this area done more excellent, minimal attenuation. Second, the scene anti-jamming capability. This is a problem that can not be ignored. Ordinary inductive sensors are easily interfered by motor or inverter. Many technicians only select the corresponding strong anti-electromagnetic interference sensor for applications nearby. But in the car manufacturing workshop, plant large, on-site technical staff used to use the Throttle Position Sensor walkie-talkie communication, especially when walking with a walkie-talkie dialogue, will inadvertently close to the sensor, resulting in a brief failure. ELCO company on the C40 series of products in this area is very concerned about, to enhance its overall electromagnetic compatibility, to avoid causing malfunctions.
Moreover, the installation side. With the popularity of inductive sensors, sensors not only in terms of electrical performance has improved, the mechanical aspects of the design more and more humane. In this application, the C40 inductive sensor sensing surface can be easily adjusted to 5 directions. Without any tools to help, do not cut off the power supply, output plug-in, just by manual operation can be. The installation of different detection directions to provide a convenient use, the greatest degree of realization of the human installation. Reduced stocking of multiple similar products and reduced installation and maintenance time.
Finally, the stability of the operation of the protection. C40 has IP67 protection level, in the use Pressure Switch of the depot, put an end to any oil, dust erosion. In addition, when the track through the track, the vibration is long-standing, C40 excellent anti-vibration is also in this application has played a very important role.
