What are the measures to prevent corrosion temperature instrument?

How to prolong the life of the instrument? That is about to do protection measures about the temperature instrument, instrument for temperature protection measures are taken, consider the measurement of the medium and the environment, said the below several anticorrosion measures: 1. Adopt the method of isolation, isolation is not directly measured medium in contact with the instrument or components, components. Some direct impact in the measuring tube note spacer, by adopting the method of isolated container or the diaphragm. For viscous medium, toxic medium, alkali solid medium or vaporization and condensation in ambient temperature, crystallization and precipitation of dielectric isolation method implementation measure may be adopted. 2. By blowing method and method of liquid measurement or can make up for the isolation method is difficult to meet the requirements of occasions, both to protect the instrument, to achieve the purpose of measurement. Purge method is applied to the corrosion resistance, viscosity, crystallization, melting, sedimentary medium, pressure, flow rate of liquid level measurement. 3. , bracket and foundation for steel structure, bearing, carbon steel pipe and other steel components should be cleaning, brushing anti-corrosion paint, anti corrosion atmosphere and environment. Paint are mainly used in red lead antirust paint, bitumen paint, chlorinated polyvinyl chloride, phenolic paint, epoxy paint, etch primer, magnetic mixed paint, alkyd enamel, etc. 4. In the case of corrosive medium, instrument, selection of component materials have direct contact with the corrosive medium corrosion resistance, on the surface of parts, internal coating anticorrosion materials, or add protection tube; Used in corrosive medium measurement instrument piping, key parts, casing and other corrosive medium contact and the use of corrosion resistant material, stainless steel, teflon, corrosion-resistant materials such as plastic, lined with rubber. When we were in the use of instruments and meters, must pay attention to the corrosion protection instrument and meter, such not only can prolong the life of the instrument and keep the accuracy of measurement, no pollution measured medium such as benefits, and can save the cost of the most important! ! ! !
