As a leading supplier in the global instrumentation market, Rossonix Co., Limited leverages over a decade of experience since 2011 to provide reliable industrial solutions. Our EJA510A and EJA530A series of Absolute and Gauge Pressure Transmitters are engineered to deliver precise and stable pressure measurement in demanding environments. We understand the critical need for accuracy and durability in process control, which is why we offer these robust transmitters, backed by our ISO9001 certified quality management system and a significant annual export volume. These instruments are designed to enhance operational efficiency and reliability for our clients across diverse markets from North America to Oceania.
The EJA series transmitters are built to meet the rigorous demands of modern industrial applications. They feature a highly stable sensor and advanced digital technology to ensure long-term performance with minimal drift.
- Dual-Type Versatility: The series includes models for both absolute pressure (EJA510A) and gauge pressure (EJA530A) measurement, providing flexibility for various system requirements.
- Superior Sensor Technology: Utilizes a single-crystal silicon resonant sensor, renowned for its exceptional stability, high accuracy, and resistance to vibration and shock.
- Robust Construction: The housing is designed for harsh conditions, and the standard 316L stainless steel diaphragm ensures compatibility with a wide range of media.
- Advanced Communication: Supports industry-standard protocols like 4-20mA HART and FOUNDATION Fieldbus, enabling seamless integration into both conventional and digital plant architectures.
- User-Friendly Configuration: Easy setup and calibration via handheld communicators or integrated control system software, reducing maintenance time and complexity.
- Wide Application Scope: Suitable for critical processes in oil & gas, chemical, pharmaceutical, power generation, water treatment, and food & beverage industries.

Frequently Asked Questions (FAQ)
-
What is the main difference between the EJA510A and EJA530A models?
The EJA510A is designed for absolute pressure measurement, which uses a perfect vacuum as its reference point. The EJA530A is for gauge pressure measurement, which uses atmospheric pressure as its reference. The choice depends on your specific process requirements. -
Can these transmitters be used with corrosive media?
The standard diaphragm is 316L stainless steel, which offers good general corrosion resistance. For highly corrosive applications, alternative diaphragm materials such as Hastelloy C-276 or Tantalum may be available upon request. -
What communication protocols are supported?
The standard output is a 4-20mA analog signal with superimposed HART digital communication. For fully digital networks, FOUNDATION Fieldbus versions are offered as an optional configuration. -
How is the transmitter calibrated and configured?
Configuration and calibration can be performed using a standard HART handheld communicator or via the control system software if using the Fieldbus version. No special tools are required for basic setup. -
What is the typical lead time for an order?
Lead times vary based on model, configuration, and order quantity. As a trading company with established supply chains and overseas offices, we strive to offer competitive lead times. Please contact us with your specific requirements for a precise quotation and delivery schedule. -
