Основные преимущества и выгоды
Elite Draft Range Sensitivity: Unlike general-purpose transmitters that struggle at the bottom of their range, the EJX120A is built with a true draft range capsule. This allows for stable and accurate measurement of extremely low differential pressures, ensuring precise control over furnace air-to-fuel ratios and minimizing energy waste.
Industry-Leading Accuracy: With a standard reference accuracy of ± 0.09% of span, the EJX120A provides the granular data required for advanced process optimization. This precision is vital for maintaining the near-neutral pressure points required in glass melting or specialized chemical vapor deposition processes.
Superior Long-Term Stability: Low-pressure sensors are notoriously prone to drift, but the EJX120A is rated for ± 0.15% stability per year. This reliability reduces the frequency of manual zero-adjustments and recalibration cycles, ensuring that your safety and control loops remain consistent over long operating periods.
Certified for Safety Instrumented Systems: Reliability is backed by Exida and TUV SIL 2/3 certification. The EJX120A provides the dependable monitoring needed for safety-critical applications, such as detecting back-drafts in boilers or ensuring the integrity of hazardous exhaust systems.
Rapid Dynamic Response: Featuring a 150 ms response time, the transmitter provides fast feedback to the control system. This speed is essential for protecting large-scale boiler structures from sudden pressure surges or “puffs” that can occur during rapid load changes or ignition.
Direct Field Configuration (LPS): The Local Parameter Setting feature allows operators to adjust the range and basic parameters using the external indicator without needing a handheld terminal. This simplifies commissioning and maintenance in the field, saving time and reducing the need for extra equipment.
