One Instrument, Multiple Capabilities, Precise Traceability: The Yokogawa EJX910A Genuine Imported High-Accuracy Multivariable Transmitter
In process industries such as oil, gas, and chemicals, measuring critical parameters like flow, pressure, and level often requires installing multiple single-function instruments. This not only increases equipment investment but also raises installation complexity and maintenance costs. Xi'an Xinyi Instrument Technology Co., Ltd. brings you the industry's "smart choice"—the Genuine Japanese Imported Yokogawa EJX910A Multivariable Transmitter. This product transcends traditional single-measurement modes by integrating the measurement of three core variables—differential pressure, static pressure, and process temperature—into one unit. Leveraging this, its powerful built-in computation function directly outputs high-precision mass flow fully compensated for temperature and pressure. With its typical reference accuracy of ±0.04%, 120:1 turndown ratio, robust IP67 protection, and quality of Japanese manufacturing, the EJX910A delivers unprecedented comprehensive efficiency and precision for measuring gas, steam, and liquid in demanding applications, making it the ideal choice to replace traditional single-variable measurement solutions.
Core Product Highlights: Multivariable, High Accuracy, High Integration
1. Revolutionary Multivariable Sensing TechnologyThe core advantage of the EJX910A lies in its multivariable sensing capability. It is not simply a assembly of several sensors, but uses single-crystal silicon resonant sensing technology to simultaneously sense differential pressure and static pressure on the same chip, while also being able to connect an external RTD to acquire process temperature. This integrated design ensures the synchronization and correlation of multi-dimensional data at the hardware level.
2. Built-in Computation, Direct Mass Flow OutputThe "intelligence" of the EJX910A is reflected in its powerful internal calculation function. It takes the acquired differential pressure, static pressure, and temperature values, combines them with internally stored flow calculation formulas, performs real-time temperature and pressure compensation and computation, and finally directly outputs a 4-20mA signal proportional to the mass flow. All process variables are also accessible via digital communication. This means users no longer need to configure additional flow computers, significantly simplifying system architecture and reducing overall costs.
3. Exceptional Accuracy and Superior StabilityContinuing the legendary heritage of the Yokogawa EJA series, the EJX910A boasts impressive performance parameters. Its differential pressure measurement accuracy reaches ±0.04%, with a turndown ratio of up to 120:1 and excellent long-term stability. Combined with a rugged all-stainless steel construction and IP67 protection rating, it confidently withstands challenges from vibration, temperature, and humidity in harsh environments like offshore platforms and chemical plants, ensuring long-term reliable operation.

Classic Reliability, Intuitive Precision: The New Instrument YB-150 Series 4-Inch Mechanical Pressure Gauge
In an era where digital technology is sweeping through the industrial sector, the mechanical analog pressure gauge still plays an irreplaceable role in countless on-site monitoring tasks, thanks to its unique advantages of requiring no power supply, rugged durability, and intuitive readability. Xi'an Xinyi Instrument Technology Co., Ltd., deeply understanding the timeless value of classic instrumentation, proudly introduces the YB-150 Series 4-inch (100 mm) Mechanical Pressure Gauge. Specifically designed for routine pressure monitoring within the range of 0 to 600 PSI, this product utilizes the proven Bourdon tube (phosphor bronze) sensing principle. Combined with a clearly legible 4-inch dial and a standard 1/4-inch NPT connection, it offers reliable accuracy of ±1.5% FS, wide temperature adaptability from -40°C to 60°C, and a stainless steel case, making it the ideal auxiliary choice for HVAC systems, air compressors, water pumps, and various general industrial equipment.
Core Product Highlights: Classic, Durable, At a Glance
1. All-Mechanical Structure, Ultimate Reliability Without PowerThe core value of the YB-150 lies in its all-mechanical design. It relies entirely on the internal phosphor bronze Bourdon tube, which elastically deforms under pressure, driving a pointer via a precision linkage to indicate pressure on the dial. The entire process requires no external power, fundamentally eliminating electrical faults, electromagnetic interference, and explosion-proof hazards. This makes it the most stable and reliable monitoring choice for high-safety applications like the chemical and petroleum industries, as well as areas without on-site power supply.
2. 4-Inch Large Dial, Clearly Readable from a DistanceThe product features a clear 4-inch (100 mm) diameter dial with distinct graduations and a prominent pointer. Even in low-light conditions or when installed at a distance, operators can quickly and accurately read the current pressure value. This intuitive analog display allows observers to instantly perceive pressure changes and trends through the pointer's position and swing – a unique advantage not offered by digital displays.
3. Rugged Construction and Standard Connection, Easy to IntegrateThe YB-150 is equipped with a stainless steel case, effectively resisting oil, moisture, and general corrosion. Its 1/4-inch NPT standard tapered pipe thread connection is an industry standard in North America and internationally, offering strong compatibility and easy installation on various pipes, valves, and equipment. The bottom-mounted design is simple and sturdy, suitable for most panel or direct-mounting scenarios.
