壓力傳感器是一種應(yīng)用最為廣泛的傳感器，跟金屬管轉(zhuǎn)子流量計一樣，被廣泛的應(yīng)用于工業(yè)、化工、醫(yī)療、智能建筑、航空航天、電子、軍用、船舶、機床等多個行業(yè)當(dāng)中。壓力傳感器在生產(chǎn)的時候需要有一定的防腐功能，壓力傳感器不僅在生產(chǎn)的時候有一定的防腐功能，在日常的使用中用戶也是需要了解一些防腐的知識的，這樣可以避免壓力傳感器被腐蝕的問題，下面昆山丹瑞傳感測控介紹一下壓力傳感器的防腐方法吧。首先，了解被測介質(zhì)是否與316L相兼容：316，317L合金在100小時5%鹽霧測試中，都沒有出現(xiàn)腐蝕。
其次，在選購傳感器產(chǎn)品時，向供應(yīng)商咨詢介質(zhì)對壓力傳感器是否有影響;通過對彈體耐腐蝕材料的選擇，以便達(dá)到用戶使用的需求。
最后，我們可以采用隔離辦法：壓力變送器前有鉬2鈦和鉭片，膜片與彈道管之間用甲基硅油傳送壓力，最小量程可做到0～100kPa，如果膜片材料還不耐腐，則可加一層F46膜片，但儀表靈敏底有所降低。也可直接用F46作隔離膜片，傳遞液可選用氟油，則可起雙重隔離作用。
壓力傳感器在使用過程中一旦發(fā)現(xiàn)其不能與介質(zhì)兼容就必須馬上更換傳感器，對應(yīng)一些特殊的介質(zhì)我們可以采用特殊的材質(zhì)或者特殊的結(jié)構(gòu)來進(jìn)行測量，壓力傳感器未來肯定會得到更加廣泛的應(yīng)用。
Pressure sensor is one of the most widely used sensors. Like metal tube rotor flowmeter, it is widely used in industry, chemical industry, medical treatment, intelligent building, aerospace, electronics, military, ship, machine tool and other industries. Pressure sensors need to have a certain anti-corrosion function in production. Pressure sensors not only have a certain anti-corrosion function in production, but also need to know some anti-corrosion knowledge in daily use. This can avoid the corrosion of pressure sensors. The following is an introduction to Kunshan Than Shwe sensor measurement and control. Lower pressure sensor's anti-corrosion method. First of all, to know whether the tested medium is compatible with 316L: 316, 317L alloy in 100 hours of 5% salt spray test, there is no corrosion.
Secondly, when purchasing sensor products, consult the supplier whether the medium has an impact on the pressure sensor; through the selection of corrosion-resistant materials of the projectile, in order to meet the user's needs.
Finally, we can use isolation method: the pressure transmitter in front of molybdenum 2 titanium and tantalum, diaphragm and ballistic pipe between the transmission pressure with methyl silicone oil, the minimum range can be 0-100 kPa, if the diaphragm material is not corrosion-resistant, you can add a layer of F46 diaphragm, but the instrument sensitive substrate is reduced. F46 can also be used as isolation membrane directly, and the transfer fluid can be selected with fluorine oil.
Once the pressure sensor is found to be incompatible with the medium, it must be replaced immediately. For some special media, we can use special materials or special structures to measure. The pressure sensor will certainly be more widely used in the future.
