YOKOGAWA EJX438A Diaphragm Sealed Gauge Pressure Transmitter
Multi-sensing, an Evolution in the Silicon Resonant Sensor
Diaphragm seal is used to prevent process medium form entering directly into the pressure-sensing assembly of the pressure transmitter, it is connected to the transmitter using capillary filled with fill fluid.
YOKOGAWA EJX438A Diaphragm Sealed Gauge Pressure Transmitters can be used to measure liquid, gas, or steam flow, as well as liquid level, density, and pressure.
The multi-sensing technology provides the advanced diagnostic function to detect such abnormalities as an impulse line blockage.
The EJX series is available with BRAIN, HART, and FOUNDATION™ fieldbus communication protocols.
