Product Description

The  EJA130E  high static pressure differential pressure transmitter adopts single crystal silicon resonant sensor technology, which  is suitable for measuring the flow rate, liquid level, density, and pressure of liquids, gases, or vapors. EJA130E  converts the measured differential pressure into a 4-20mA DC current signal output, which can measure, display, or  remotely monitor static pressure. It has functions such as fast response, remote setting, and self diagnosis.

Core technical parameters

1. Measurement System: Adopts a monocrystalline silicon resonant sensor that directly outputs digital signals,      eliminating conversion errors of analog signals.

2. Range and Accuracy: Two options are available, including medium capsule (M: 1–100kPa) and high capsule (H:      5–500kPa). The reference accuracy reaches ±0.055%, the long-term stability is ±0.1% URL per 10 years, and the      turndown ratio is 100:1.

3. Pressure Resistance: Maximum Working Static Pressure (MWP) is 32MPa (4500psi), with a burst pressure up to 132MPa.      It is suitable for harsh environments such as high-pressure vessels and long-distance transmission pipelines.

4. Output and Communication: The standard output is a 4–20mA DC two-wire signal superimposed with HART or BRAIN      digital communication; protocols such as FF Fieldbus and PROFIBUS PA are also optional, compatible with mainstream      control systems

5. Environmental Adaptability: Process temperature range from -40 to 120℃, protection class up to IP66/IP67 and NEMA      4X, with multiple safety certifications including SIL 2/3, ATEX and NEPSI.

Core Functions and Advantages

1. Three-parameter synchronous measurement: It can simultaneously measure differential pressure, static pressure and      process temperature, and achieve higher measurement accuracy through dynamic compensation.

2. Excellent Reliability: It maintains stable measurement under static pressure up to 32MPa, and its long-term      stability significantly reduces the frequency of regular calibration and maintenance costs.

3. Powerful Diagnostic Capability: Built-in more than 40 self-diagnosis functions and Back-Check function, supporting      rapid fault location and preventive maintenance

4. Flexible Installation and Configuration: Supports integrated or split installation, equipped with optional local      LCD display, enabling on-site viewing of differential pressure, static pressure, temperature and diagnostic      information
