Product Overview

The Yokogawa F9300AJ is a specialized electronic assembly used within Yokogawa differential pressure measurement systems. It functions as a key processing component that converts physical pressure-induced membrane displacement into accurate electrical signals for use in control systems such as CENTUM VP and STARDOM. Designed for applications including flow, level, and density measurement in liquid, gas, and steam processes, the F9300AJ ensures stable and precise signal conditioning. Supplied as 100% brand new, original hardware manufactured in France, this unit is engineered to deliver high reliability, accuracy, and long-term operational stability.

Technical Specifications

Engineering Advantages

Ultra-Compact Electronic Footprint
The slim 18 mm profile allows the module to be integrated into compact transmitter housings, making it suitable for installations in tight spaces such as skid-mounted systems or dense piping environments.

High-Fidelity Signal Processing
Embedded microprocessor-based compensation algorithms correct for temperature variations and static pressure effects, maintaining measurement accuracy under varying environmental conditions.

Low-Mass Construction
At only 150 g, the lightweight design minimizes mechanical stress and vibration impact, contributing to improved stability and extended component lifespan.

Global Standard Compliance
Manufactured in France with strong EMC shielding, the unit resists electromagnetic and radio frequency interference, ensuring reliable 4–20 mA signal transmission in electrically noisy industrial environments.

FAQs

Is the F9300AJ a complete transmitter?
No, it is typically an internal electronic assembly that must be installed within a compatible Yokogawa transmitter housing to function as a complete measurement device.

Does it support HART communication?
Yes, it supports HART communication, enabling remote configuration, diagnostics, and integration with standard HART tools and software platforms.

How is calibration performed?
Calibration involves installing the module into the sensor housing and performing zero and span adjustments using a pressure calibrator or deadweight tester.

What is its expected service life?
It is designed for long-term industrial use, typically exceeding 10 years under proper operating and environmental conditions, provided the enclosure is properly sealed and maintained.
