YOKOGAWA DPHARP EJA220A STYLE S1 TRANSMITTER

Description:

The Yokogawa EJA220A Style S1 is a DPharp differential pressure transmitter designed for high-accuracy measurement in challenging process conditions. It is a flange-mounted model specifically suited for applications involving viscous, crystallizing, or slurry-type fluids. Using Yokogawa’s resonant silicon sensor technology, it delivers stable, long-term accurate measurements with strong resistance to temperature and pressure changes. The transmitter converts differential pressure into a standard output signal for control systems.

Applications:

The Yokogawa EJA220A transmitter is used in process control systems for measuring differential pressure in liquids, slurries, and dense media. The Yokogawa transmitter is commonly installed on tanks, vessels, and separators for level measurement, density monitoring, and process control in industries such as chemical processing, oil & gas, and manufacturing.
