Yokogawa EJX118A-EHSCG-919DJ-WA43C2HW00-AA26/KS21/D3/TF1 Differential Pressure Transmitter 

The Yokogawa EJX118A, a diaphragm-sealed differential pressure transmitter, works by utilizing a DPharp sensor to measure differential pressure, static pressure, and sensor temperature. This sensor converts the pressure difference into an electrical signal, which is then outputted as a 4-20 mA DC signal. The transmitter also incorporates advanced diagnostics to detect issues like impulse line blockages and monitor heat traces
