Yokogawa EJA438E-JASCG-917DB-WA13C1SW00-AA25 Diaphragm Seal Pressure Transmitter Unit

Feature & Principle

This transmitter uses single crystal silicon resonant pressure sensing technology. The process pressure acts on the remote diaphragm, transmits pressure to the internal sensor through capillary filling liquid, converts pressure signal into 4-20mA analog signal with HART digital protocol. It supports remote parameter configuration and self-diagnosis, effectively avoids medium blocking, corrosion and high temperature impact on the sensor body.
