Diaphragm seal is used to prevent process medium form entering directly into the pressure-sensing assembly of the pressure transmitter, it is connected to the transmitter using capillary filled with fill fluid.

EJX438A Diaphragm Sealed Gauge Pressure Transmitters can be used to measure liquid, gas, or steam pressure. EJX438A outputs a 4 to 20 mA DC signal corresponding to the measured pressure. It also features quick response, remote setup and monitoring via BRAIN or HART communications, and diagnostics and optional status output for pressure high/low alarm.

The multi-sensing technology provides the advanced diagnostic function to detect such abnormality as an impulse line blockage. FOUNDATION Fieldbus and PROFIBUS PA protocol types are also available. All EJX series models in their standard configuration, with the exception of the Fieldbus and PROFIBUS types, are certified by TÜV as complying with SIL 2 for safety requirement.
