$545.00

The Yokogawa EJA130E is a high-performance differential pressure transmitter developed for process applications where accurate measurement is required under high static pressure. Its DPharp digital sensor provides stable differential pressure measurement while also monitoring static pressure and sensor temperature.

With a robust pressure design, universal mounting, multiple communication options, and a maximum pressure limit of 4,500 psi, the EJA130E is suitable for demanding flow, level, density, and pressure measurement applications.

The Yokogawa EJA130E Differential Pressure Transmitter is designed specifically for high static pressure applications where reliable differential pressure measurement is essential. It is suitable for measuring the pressure of liquids, gases, and steam, and can be applied to flow, liquid level, density, and process pressure measurement.

The EJA130E uses Yokogawa's DPharp single-crystal silicon resonant sensor. The sensor provides digital measurement information and can measure differential pressure, static pressure, and sensor temperature. This multi-sensing capability allows the transmitter to compensate for the effects of static pressure and temperature, helping maintain stable measurement performance under changing process conditions.

The transmitter provides a reference accuracy of ±0.055% of DP span for the primary differential pressure variable. Its 100:1 rangeability allows flexible configuration across different measurement requirements, while long-term stability is specified at ±0.1% of URL per 10 years under normal operating conditions. The over-pressure effect is specified at ±0.03% of URL.

A key advantage of the EJA130E is its ability to operate in high static pressure environments. The specified maximum pressure limit is 4,500 psi for all capsules, while the burst pressure is specified at 19,100 psi (132 MPa). This makes the transmitter particularly suitable for demanding process installations where both differential pressure and high line pressure must be considered.

The EJA130E can also measure static pressure as a secondary variable. The static pressure value can be shown on the integral indicator or monitored remotely through BRAIN or HART communication. This multi-variable capability can provide additional process information without requiring a separate pressure transmitter for the same measurement point.

Multiple communication configurations are available, including 4–20 mA DC with BRAIN, 4–20 mA DC with HART 5/HART 7, FOUNDATION Fieldbus, PROFIBUS PA, and 1–5 V DC low-power output with HART 7. Remote setup, self-diagnostics, and digital communication support convenient commissioning and maintenance.

The EJA130E also uses IEC 61518-compliant process connection dimensions and a universal mounting concept. Yokogawa provides flexible vent and drain configurations to accommodate different installation requirements. The transmitter is also available with a range of manifolds and accessories for differential pressure applications.
