Yokogawa EJX910-EMS4G-912DB-3B Transmitter Inquiry Item

Product Description

EJX910-EMS4G-912DB-3B is Yokogawa DPharp EJX910 multivariable mass flow transmitter. It adopts single crystal resonant sensor technology, which can simultaneously measure differential pressure, static pressure and process temperature, and calculate fully compensated mass flow inside the transmitter. It supports 4-20mA output with HART communication protocol, built-in powerful self-diagnosis function conforming to NAMUR NE107. It is widely used for gas, steam and liquid flow measurement in petrochemical, power and refining plants.
