Product DescriptionProduct DescriptionYokogawa EJA210E Flange Mounted Differential Pressure TransmitterThe EJA210E Flange Mounted Differential Pressure Transmitter, developed by Yokogawa Electric Corporation—a global leader in industrial automation and control solutions—represents a pinnacle of precision measurement technology tailored for demanding industrial environments. Designed specifically for differential pressure (DP) measurement in processes where direct flange mounting is critical, this transmitter integrates advanced sensor technology, robust mechanical design, and intelligent functionality to deliver reliable, accurate, and long-term performance.Unlike traditional differential pressure transmitters that require external impulse lines (which often introduce measurement errors due to clogging, temperature fluctuations, or fluid stagnation), the EJA210E features a direct flange-mounted design. This design eliminates the need for impulse lines by mounting the sensor directly to the process flange, ensuring that the measurement is taken at the point of interest—minimizing lag time, reducing maintenance costs, and enhancing overall measurement accuracy.The EJA210E is engineered to meet the diverse needs of industries such as oil and gas, chemical processing, power generation, water and wastewater treatment, and pharmaceutical manufacturing. It is capable of measuring differential pressure ranges from as low as 0–100 Paup to 0–4000 kPa , making it suitable for both low-pressure and high-pressure applications. Additionally, it supports static pressure ratings of up to 42 MPa , enabling its use in high-pressure process vessels and pipelines.Housing and EnclosureThe transmitter's housing is constructed from aluminum alloy (for lightweight applications) or 316L stainless steel (for corrosive environments) and is rated for IP67 or IP68 protection—meaning it is dust-tight and waterproof, even when submerged in water for extended periods. This makes the EJA210E suitable for outdoor installations or areas where water or dust ingress is a concern.The housing features a modular design that allows for easy access to internal components (such as the circuit board and communication ports) during maintenance. The front panel includes a large, backlit LCD display that shows key measurement data (e.g., differential pressure, static pressure, temperature) and diagnostic information. The display is visible even in low-light conditions and can be rotated 360 degrees for easy viewing, regardless of the transmitter's mounting orientation.How the Silicon Resonator Sensor Works?The sensor consists of a thin silicon diaphragm etched with two identical resonant beams (vibrating elements) on either side of the diaphragm. When differential pressure is applied to the diaphragm, it deflects—causing one resonant beam to experience tension (increasing its resonant frequency) and the other to experience compression (decreasing its resonant frequency). The difference between these two frequencies is directly proportional to the applied differential pressure.This dual-beam design provides several key advantages:High Accuracy: The frequency difference is measured with extreme precision (up to ±0.075% of span), ensuring that the EJA210E meets even the most stringent measurement requirements.Long-Term Stability: Silicon is inherently stable over time, and the absence of moving parts (other than the vibrating beams) reduces wear and tear, resulting in a zero drift of less than ±0.01% of span per year.Immunity to Environmental Interference: The sensor is insensitive to temperature fluctuations (thanks to built-in temperature compensation), vibration, and electromagnetic interference (EMI), ensuring consistent performance in harsh industrial environments.Mechanical Design and Construction1.Flange and Process ConnectionThe EJA210E is available with a variety of flange sizes and ratings to match different process requirements. Standard flange options include ANSI Class 150, 300, 600, and 900, as well as DIN and JIS flanges, ensuring compatibility with global piping standards. The flange material is typically 316L stainless steel (a corrosion-resistant alloy), but Hastelloy C-276 or Monel 400 options are available for applications involving highly corrosive fluids (e.g., acids, alkalis, or saltwater).The flange is designed with a smooth, crevice-free surface to prevent fluid accumulation and contamination—critical for applications in the pharmaceutical and food and beverage industries, where hygiene is a top priority. Additionally, the flange's gasket groove is compatible with standard gaskets (e.g., PTFE, graphite, or metal), ensuring a secure, leak-tight seal.2.
