Product Description

Product Description

The  EJX530A  high-performance pressure transmitter adopts single-crystal silicon resonant sensor technology and is suitable for  measuring the pressure of liquids, gases or steam. The  EJX530A  converts pressure into a 4~20mA DC current signal output and features fast response, remote configuration,  self-diagnosis and other functions.


Main Functions

  1. DPharp Digital Sensing: Outputs digital signals directly, reduces errors from digital-to-analog conversion, and  delivers more stable measurements.

  2. Remote Operation & Maintenance: Realize remote configuration, monitoring and diagnosis via HART/BRAIN to   reduce on-site workload.

  3. Local Configuration (LPS): Complete parameter settings via buttons without a handheld communicator, enabling   efficient on-site commissioning.

  4. Advanced Self-Diagnosis: Detects abnormalities such as pressure impulse pipe blockage and heat tracing faults to    provide early risk warning.

  5. 10-segment signal curve: capable of nonlinear compensation and suitable for complex applications such as tank and   flow measurement.


Core Advantages

  1. Ultra-high Accuracy: Measurement accuracy reaches ±0.04% of span, ensuring precise process control.

  2. Ultra-long Stability: ±0.1% URL stability over 15 years, greatly reducing calibration and maintenance costs.

  3. Fast Response: Response time of 90 ms, capturing dynamic pressure changes in real time.

  4. Overpressure Resistance: Maximum withstand pressure 7200 psi (approximately 50 MPa), with impact resistance and  high reliability.

  5. Multi-communication Compatibility: Supports HART 5/7, BRAIN, FF Fieldbus, and PROFIBUS PA.

  6. Safety Certification: Certified by Exida and TUV SIL 2/3, compatible with Safety Instrumented Systems (SIS).


Typical Applications

  1. Petrochemical Industry: Gauge pressure monitoring and control of reaction kettles, distillation towers and storage  tanks.

  2. Electric Power Energy: Pressure monitoring for boilers, steam turbines and compressor units.

  3. Metallurgical Industry: Pressure measurement for blast furnaces, heating furnaces and hydraulic systems.

  4. Water treatment: Pressure monitoring of pipelines, filters and pumping stations.

Pressure Transmitter FAQ

What is a pressure transmitter used for?

A pressure transmitter converts the pressure of liquid, gas or steam into a standard electrical signal for PLC, DCS, recorder or control instrument input. It is widely used for pipeline pressure, tank level, flow measurement and process safety monitoring.

How do I choose the right pressure transmitter?

Confirm the pressure range, pressure type, medium, temperature, output signal, accuracy, installation thread, electrical connection and environmental requirements. For corrosive media, high temperature or sanitary applications, diaphragm material and sealing structure are especially important.

What is the difference between gauge, absolute and differential pressure transmitters?

Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure pressure relative to vacuum. Differential pressure transmitters measure the pressure difference between two points and are commonly used for flow, filter and level measurement.

Can Xinyi Instrument provide customized pressure transmitters?

Yes. Xinyi Instrument can support customized pressure ranges, process connections, output signals, cable length, display options and model selection for different industrial applications.
