When using a high-pressure transmitter in ultra-high-pressure equipment, how should the mounting connection and safety margin be determined? This article covers key considerations, including operating pressure and transient peaks, compatibility of threads and sealing structures, the difference between range and overpressure limits, and verification of the entire pressure-bearing assembly. It provides clear selection guidance and explains the essentials of dynamic measurement, installation acceptance, and document preparation. Click to learn practical verification methods, reduce the risk of interface incompatibility and insufficient pressure resistance, and support safe equipment operation and reliable measurement.
