Yokogawa’s wireless differential pressure transmitters, including models such as the EJX110B, EJX210B, and EJX530B, deliver exceptional reliability and precision. Engineers rely on these transmitters to monitor pressure drop, flow rate, and tank level without the need for extensive cabling. Built on ISA100 wireless communication standards and utilizing Yokogawa’s DPharp single-crystal silicon resonant sensor technology, these devices provide superior stability and accuracy, even in demanding industrial environments.
Key Features and Benefits
Yokogawa’s DPharp sensor technology resists corrosion and drift, maintaining stable output and accuracy over time. This eliminates the need for frequent recalibration, ensuring dependable performance. The transmitters operate on ISA100 wireless protocols, making them easy to integrate into modern wireless networks and ideal for installations where running wiring is difficult or costly.
The EJX110B is designed for general differential pressure measurement across gas, liquid, and steam applications. The EJX210B is suited for flange-mounted installations, often used in industrial piping systems or skids. The EJX530B is designed for inline mounting in pipelines and vessels, featuring rugged construction and high-pressure capability.
These transmitters feature long battery life and built-in innovative diagnostics. They continuously monitor temperature, signal strength, and sensor health, providing proactive notifications to operators. Safety and compliance are also key strengths, with global hazardous area certifications and SIL-rated options available to meet demanding regulatory requirements.
Typical Applications
Yokogawa wireless differential pressure transmitters excel in several industrial applications. They measure flow rates by monitoring the differential pressure across orifice plates and flow nozzles, providing accurate data without the cost and complexity of hardwiring. They are also widely used in filter monitoring, where changes in differential pressure indicate clogging or fouling of the filter. For tank level measurement, placing transmitters at the bottom zones of tanks delivers accurate level readings without the need for intrusive wiring. Remote and hazardous locations, such as flare stacks, pits, and cooling towers, benefit significantly from the flexibility of wireless deployment.
Why Choose Yokogawa Wireless DP Transmitters?
Yokogawa builds its wireless transmitters using high-grade industrial materials to ensure long-term stability and durability. The resonant silicon sensor is designed to resist fouling and corrosion, making it highly reliable in harsh environments. The wireless capability accelerates installation, reduces maintenance costs, and lowers the total cost of ownership. These transmitters integrate seamlessly with Yokogawa’s Plant Resource Manager (PRM) and other digital asset management systems, making them a wise choice for process automation.
Deployment Tips
To ensure optimal performance, a well-planned wireless mesh network is essential. ISA100 nodes should have redundant paths to maintain reliable communication. Choosing the right model for the application is also critical—inline designs like the EJX530B are best for pipeline systems, while flange-mounted versions like the EJX210B suit tank and vessel applications. Regular battery checks and diagnostic reviews help maintain consistent performance, and integration with existing distributed control systems or gateways ensures smooth operation.
Yokogawa Wireless Differential Pressure Transmitters stand out for their combination of stability, flexibility, and application versatility. They provide accurate measurements across a range of processes involving gas, liquid, and steam, helping facilities achieve greater operational efficiency.
