EJA130 Differential Pressure Transmitter YOKOGAWA

EJA-E Pressure Transmitters

The EJA-E range of transmitters is Yokogawa’s most recent evolution of the DPharp family of pressure transmitters, being released in 2012. It combines the ruggedness and success of the workhorse EJA-A range with the class-leading technology and performance of the EJX. It offers enhanced performance and reliability with built-in safety certification. Its small form factor and rugged materials provide the level of robustness that is expected from Yokogawa products.

EJA130E:

The high performance differential pressure transmitter EJA130E features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam low as well as liquid level, density and pressure. EJA130E outputs a 4 to 20 mA DC signal corresponding to the measured differential pressure.

Its 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 and PROFIBUS PA protocol types are also available. All EJA-E series models in their standard coniguration, with the exception of the Fieldbus and PROFIBUS types, are certiied as complying with SIL 2 for safety requirement.
