How can the diaphragm of a strong-acid pressure transmitter be protected from corrosion and perforation? This article examines key selection considerations for diaphragm materials and the overall wetted structure in relation to acid type, concentration, temperature, and impurities. It also introduces installation protection, inspection and troubleshooting, and leak response methods. General-purpose stainless steel products are not necessarily suitable for strong-acid applications; suitability must be verified against actual operating conditions.
