Diaphragm seal systems are ideal for many processes in the chemical industry as a resistant and safe measuring solution, for example, to monitor the level in a reactor using differential pressure. Precisely for this task, a manufacturer of terephthalic acid (Purified …
Corrosion
Positive material identification test (PMI)
| Kai Grabenauer | Know-howThe positive material identification test - PMI test - serves as a proof of the alloying constituents present in the material, confirming the melting analysis of the material contained in the 3.1 certificate. There are two different test procedures common for …
Grounding of submersible pressure transmitter or level probes prevents corrosion
| Enrico Bossart | Know-howIn industrial applications, the corrosion of pressure sensors is a rather negligible phenomenon, since in the majority of applications, oils (in particular hydraulic oils) are used, and contact with the pressure medium is mainly limited to the pressure channel and the …
