Pressure transducer is a device that can sense pressure signal and convert pressure signal into available output electric signal according to certain rules. It is usually composed of pressure sensitive element and signal processing unit.
Pressure sensors are widely used in all walks of life, especially in industry, such as TPMS. However, it is generally required that the pressure sensor can resist corrosion in industry. The pressure sensor connector and cavity are made of imported stainless steel as a whole. The stainless steel material used as the pressure transmitter body has high corrosion resistance and good attenuation performance, and can monitor any medium compatible with 316L. Next, we will introduce the anticorrosion techniques of pressure sensor.
(1) First of all, understand whether the tested medium is compatible with 316L. That is to say, 316 and 317L alloy has no corrosion in 100 hours 5% salt spray test.
(2) Secondly, when purchasing sensor products, consult with the supplier whether the medium has an impact on the pressure sensor. Meet the requirements of users through the selection of the bullet body corrosion-resistant materials.
(3) Finally, isolation can be used. Before the pressure transmitter, there are molybdenum titanium and tantalum pieces. The pressure is transmitted by methyl silicone oil between the diaphragm and the ballistic tube. The minimum range can be 0-100kpa. If the diaphragm material is not corrosion-resistant, a layer of F46 diaphragm can be added, but the sensitivity of the instrument is reduced. F46 can also be used as isolation diaphragm directly, and fluorine oil can be selected as transfer fluid, which can play a double isolation role.
Once the pressure sensor is found to be incompatible with the medium in use, it must be replaced immediately. Corresponding to some special media, special materials or special structures can be used for measurement.
(1) Technological advances in major vertical industries, including oil and gas, automotive and healthcare, have led to the evolution of a variety of applications and functions of pressure sensor.
(2) The field of automobile is one of the most important users of pressure sensor. The surge of automobile production leads to the increasing demand for pressure sensor and related components. For example, the monitoring of tire pressure.
(3) Motor vehicle safety has become an important aspect of the whole automobile industry. Strict government regulations around this feature will help to promote the demand growth of pressure sensors in the automobile industry.
(4) The technology based on MEMS and NEMS has been popular with the public all the time, which leads to the growth of pressure sensor market.
(5) The use of consumer electronic pressure sensor has greatly increased, becoming the fastest-growing application field in the whole market.
(6) The maturity of the end use industries such as automotive and healthcare markets has become a major challenge to the North American and European pressure sensor markets.
(7) The rapid industrialization and vehicle production in Asian countries, such as China, Japan, India and South Korea, can be attributed to the development of the Asia Pacific pressure sensor market.
(8) The development of smart city infrastructure in Asia Pacific and the Middle East has great potential for future growth.
(9) When consumers purchase pressure sensors, they are worried about the soaring cost of installation and replacement, which may affect the pressure sensor market.
(9) In the past few years, the pressure sensor market has made rapid progress, which has had a positive impact on the competition pattern. It introduced new players to the market and expanded the scope of existing players in the market.
Wenzhou Giant Automobile Electric Appliances Co, Ltd. is a professional sensor production enterprises. It produces high-tech products such as TPMS sensor suitable for over 95% types of cars , tire sensor valves and so on.
