EJA118E Differential Pressure Transmitter
Brand: Yokogawa Electric CorporationDiaphragm seals are used to prevent process medium form entering directly into the pressure-sensing assembly of the differential pressure transmitter, they are connected to the transmitter using capillaries filled with fill fluid.
EJA118E Diaphragm Sealed Differential Pressure Transmitters can be used to measure liquid, gas, or steam flow, as well as liquid level, density, and pressure. EJA118E outputs a 4-20 mA DC signal corresponding to the measured differential pressure.
Its highly accurate and stable sensor can also measure the static pressure which can be shown on the integral indicator or remotely monitored via BRAIN or HART communications.
Other key features include quick response, remote set-up using communications, and self-diagnostics.
FOUNDATION Fieldbus, PROFIBUS PA and 1-5 Vdc with HART (low power) protocol types are also available.
All EJA-E series models in their standard configuration, with the exception of the Fieldbus, PROFIBUS and Low Power types, are certified as complying with SIL 2 for safety requirement.
