Yokogawa EJX910A Multivariable Transmitter

About this product

Product Introduction The EJX910A high-performance multivariable transmitter adopts a monocrystalline silicon resonant sensor, which can output measurements of differential pressure, static pressure, process temperature, and calculate mass flow rate. Supports multiple protocols such as HART, FOUNDATION fieldbus, and RS485 Modbus. Core Performance The core of EJX910A lies in its monocrystalline silicon resonant sensor (DPharp). This technology can achieve multi parameter measurement with one sensor, which not only has a compact structure, but also provides excellent measurement accuracy and long-term stability. Measurement accuracy: Differential pressure measurement accuracy can reach ± 0.04%, static pressure accuracy is ± 0.1%, and external temperature measurement accuracy is ± 0.5 ℃ (± 0.9 ℉)； Quality flow measurement: Through real-time full density compensation technology, high-precision quality flow measurement of ± 1.0% can be achieved, and the quality flow accumulation function is built-in. Main functional features Wide support for flow meters: Supports use with primary components such as orifice plates, nozzles, and Venturi tubes. Under the HART 7 protocol, it can also support averaging tubes and conical flow meters； Flexible output and communication Supports multiple communication protocols such as HART, FOUNDATION fieldbus, and RS485 Modbus； The HART protocol type can simultaneously output 4-20mA analog signals and pulse signals for cumulative flow, instantaneous flow, or alarm status； Advanced Diagnosis and Functionality: Equipped with software download and advanced diagnostic functions (optional), and supporting multiple functional blocks, enhancing the system's configurability and maintainability； High security and reliability Passed TUV SIL 2/3 safety integrity level certification, suitable for safety instrumented systems； The protection level is IP67, NEMA 4X, and it has multiple explosion-proof certifications such as FM, ATEX, CSA, IECEx, etc., suitable for harsh industrial environments； Measurement range: -10~10 kPa to -500~500 kPa Process temperature: -200~800℃ Turndown ratio: Differential pressure 200:1, static pressure 25:1 Long-term stability: ±0.1% URL / 10 years Operating Temperature: -40°C ~ 70°C Power supply: 12 ~ 30 VDC Protection: IP67 communication protocol： HART 5 / 7 (4~20mA + digital bidirectional) For quotation, send the complete order code, quantity and operating conditions.
