Anticorrosion measures of pressure sensor

Pressure sensor is one of the most widely used sensors, has been widely used in industrial, chemical, medical, intelligent building, aerospace, electronics, military, ships, machine tools and other industries. Pressure sensor at the time of production need to have some anticorrosive function, so the pressure sensor joint and cavity are using imported stainless steel material as a whole processing, the material attenuation function good, strong corrosion resistance, can effective corrosion protection. Pressure sensor not only has certain corrosion in production function, in the course of everyday use also need to know some knowledge of corrosion protection of the user, so that you can avoid pressure sensor by corrosion problem.

in the first place, to know whether the measured medium that is compatible with 316 L, 316317 L alloy in 5% of the 100 hours salt spray test, there was no corrosion. Second, in the choose and buy sensor products, consulting medium to suppliers have an impact on whether the pressure sensor; Through the choice of projectile corrosion resistant material, in order to achieve the demand of the users. Finally, we can use the isolation method: before the pressure transmitter has 2 titanium molybdenum and tantalum sheet, diaphragm and ballistic tube with methyl silicone oil transfer between pressure and minimum range can be 0 ~ 100 kpa, if diaphragm material is not be able to bear or endure corrupt, can add a layer of F46 film, but the bottom of the instrument is sensitive. F46 isolation diaphragm, also can be directly to deliver the liquid can choose fluorine oil, can double isolation effect.

pressure sensors in use process, once found that its not compatible with the media, you must immediately replace the sensor, the corresponding special medium we can use special materials or special structure for measurement, pressure sensor in the future will certainly get more extensive application, so as a manufacturer, we are going to adapt to the need to develop new type of pressure sensor.
