Yokogawa EJ220-S1 Differential Pressure Transmitter

The Yokogawa EJ220-S1 Differential Pressure Transmitter is a low‑pressure DP transmitter that uses Yokogawa’s DPharp digital resonant sensor to deliver precise, stable measurements in process control environments. Calibrated for a range of 0–925.4 mmH₂O, it provides a 4–20 mA output with digital communication (HART typical) and is powered from a 24 VDC loop supply. Wetted materials are stainless steel, offering corrosion resistance, and the unit supports pipe, wall, or manifold mounting. With an accuracy of ±0.075% typical for the DPharp series, this transmitter is well suited to cleanrooms, HVAC and filtration monitoring, tank level measurement, and other low‑differential‑pressure applications in pharmaceuticals, food processing, utilities, and manufacturing. Part Number EJ220-S1; technology: DPharp digital resonant sensor; common replacements include Yokogawa EJA110A / EJX110A series transmitters, Yokogawa EJX120A (higher‑performance upgrade), and Emerson Rosemount 3051 low DP transmitters.
