As we all know, the pressure transmitter uses a stainless steel isolated diaphragm OEM pressure sensor as a signal measuring element, and the resistance value changes when the pressure of the measured medium is applied, and the signal corresponding to the range is finally converted into a standard analog signal or digital signal through the zero point and sensitivity temperature compensation of a wide temperature range. Diaphragms are very important during the use of pressure transmitters. If the pressure transmitter diaphragm is damaged, it will directly render the pressure transmitter unusable. The most direct way to damage the pressure transmitter diaphragm is to touch the diaphragm directly, which is common during the installation, unloading or cleaning of pressure transmitters. The diaphragm of the pressure transmitter is generally only about 0.1mm thick, and it is easy to damage the diaphragm once it is improperly operated. Today we are going to talk about another cause of diaphragm damage – hydrogen embrittlement. Hydrogen embrittlement is hydrogen dissolved in steel, polymerized into hydrogen molecules, causing stress concentration, exceeding the strength limit of steel, and forming fine cracks inside steel, also known as white spots. For example, the gasifier contains hydrogen H2, and H2 is easy to cause hydrogen embrittlement at high temperature and pressure. Hydrogen is not a corrosive medium, but it is highly permeable. Hydrogen molecules are small and can enter the crystal cell of the metal, causing the diaphragm to break. In this way, it is easy to understand why some customers did not do anything improper to the transmitter itself, and the pressure transmitter diaphragm was damaged. Often customers feel that the pressure transmitter looks no different in appearance, the functions are similar, why is the price different? The difference lies in these details, some pressure transmitters use the world’s most advanced components such as cores and diaphragms, ensuring the high quality of products at every step, and this is what customers really need.
