Overview:
The EJA210A is a high-precision flange-mounted differential pressure transmitter from the Yokogawa DPharp series. Optimized for liquid level and density measurement in demanding industrial environments, it employs silicon resonant sensor technology to deliver exceptional stability, accuracy, and reliability. Direct flange mounting eliminates the need for impulse piping, preventing clogging, freezing, and sediment buildup in viscous or slurry-based media.
