Product Description

Product Description

Yokogawa EJA118EDP Differential Pressure Transmitter

The Yokogawa EJA118EDP Differential Pressure Transmitter is a precision-engineered device designed to deliver accurate, stable, and reliable pressure measurements in demanding industrial environments. As part of Yokogawa's renowned EJA series, the EJA118EDP incorporates advanced DPharp (Digital Pressure High Accuracy and Reliability) sensor technology, combining decades of expertise in pressure measurement with cutting-edge digital signal processing. This transmitter is engineered for applications requiring exceptional performance, including oil and gas, chemical processing, power generation, water treatment, and pharmaceutical manufacturing. With its robust design, high accuracy, and seamless integration capabilities, the EJA118EDP stands as a benchmark for differential pressure measurement in critical processes.

At the heart of the EJA118EDP is Yokogawa's proprietary DPharp sensor, which utilizes a single-crystal silicon resonant element to detect pressure differentials with unparalleled precision. This technology ensures minimal drift over time, exceptional repeatability, and immunity to mechanical stress or thermal fluctuations. The sensor converts pressure into a digital signal directly, eliminating the need for analog-to-digital conversion stages that can introduce errors. The result is a typical accuracy of ±0.065% of span, with a turndown ratio of up to 100:1, allowing the transmitter to maintain high accuracy across a wide range of operating conditions. This precision is critical for applications such as flow measurement via orifice plates, liquid level monitoring in tanks, and filter efficiency tracking, where even minor deviations can impact process efficiency or safety.

Durability is a hallmark of the EJA118EDP, designed to withstand harsh industrial environments. The transmitter features a rugged aluminum or stainless-steel housing, available in explosion-proof, flameproof, or intrinsically safe configurations for use in hazardous areas. It operates reliably in extreme temperatures (-40°C to +120°C/-40°F to +248°F) and resists corrosion in aggressive media thanks to optional wetted materials such as Hastelloy C-276 or tantalum. The device meets IP67/IP68 ingress protection ratings, ensuring resilience against dust, water, and harsh cleaning processes. 

Communication and integration are streamlined through support for industry-standard protocols, including HART, FOUNDATION Fieldbus, and PROFIBUS PA. This versatility allows seamless connectivity to distributed control systems (DCS), programmable logic controllers (PLC), and asset management software, enabling real-time monitoring and predictive maintenance. The HART protocol provides analog 4–20 mA output with digital overlay for remote configuration, while digital protocols offer enhanced diagnostics and multi-variable data transmission. Built-in self-diagnostics continuously monitor transmitter health, detecting issues such as overpressure events, sensor degradation, or communication faults, reducing unplanned downtime and simplifying troubleshooting.

The EJA118EDP excels in a wide range of applications, from measuring liquid, gas, or steam flow using primary elements like orifice plates and Venturi tubes to monitoring liquid levels in pressurized or open tanks. Its ability to handle low-pressure differentials with high sensitivity makes it ideal for detecting clogged filters, monitoring HVAC systems, or controlling combustion efficiency in boilers. In the oil and gas industry, it ensures accurate custody transfer measurements, while in pharmaceuticals, it supports compliance with stringent hygiene standards. The transmitter's compact design and universal mounting options facilitate easy installation on pipelines, vessels, or control panels, minimizing retrofitting costs.

Installation and maintenance are further simplified by the EJA118EDP's user-friendly design. The transmitter features a local display module with a backlit LCD screen for on-site parameter viewing and adjustment, even in low-light conditions. Configuration can be performed via a dedicated handheld terminal, such as Yokogawa's BT200, or through PC-based software like FieldMate, enabling quick setup and calibration. The device's modular construction also allows for easy replacement of components, reducing spare parts inventory and minimizing process interruptions.
