Yokogawa Differential Pressure Transmitter EJA118W DHHA1FB-BA02-97EA/FF1 (Style S2)

The Yokogawa EJA118W is a diaphragm-sealed differential pressure transmitter. It works by using a diaphragm seal to isolate the pressure-sensing element from the process medium, which can be liquid, gas, or steam. The pressure difference between two points is measured, and this is converted into a 4-20mA DC signal, which can be used for remote monitoring and control.
