When it comes to subsea applications, reliability and precision are everything. Offshore and underwater environments present some of the toughest conditions for instrumentation, demanding solutions that can withstand pressure, saltwater corrosion, and long-term deployment without compromising accuracy. At ESI Technology, we have spent decades developing cutting-edge solutions for these environments. One of our most advanced products is the PR3930 Subsea Pressure Transmitter with RS-485 Interface, designed specifically for performance and durability under the ocean’s surface.

What is the PR3930 Subsea Pressure Transmitter with RS-485 Interface?

The Subsea Pressure Transmitter with RS-485 Interface is a high-performance subsea pressure sensor engineered to deliver accurate measurements at depths up to 6,000 metres. Built for demanding subsea conditions, it combines robust mechanical design with advanced digital communication via the RS-485 interface.

This transmitter provides continuous monitoring of pressure in subsea systems, whether in offshore oil and gas operations, renewable energy projects, or scientific research. The RS-485 digital interface ensures reliable communication even over long distances, which is essential in subsea environments where signal degradation is a common challenge.

Key Features of the PR3930 Subsea Pressure Transmitter with RS-485 Interface

At ESI Technology, we design products with the end user in mind, ensuring that the PR3930 stands up to real-world challenges. Some of its standout features include:

• Depth Capability: Operates effectively at depths of up to 6,000m.

• RS-485 Communication: Allows robust, long-distance digital signal transmission with minimal interference.

• High Accuracy: Precision-engineered sensing technology ensures reliable and repeatable data.

• Corrosion Resistance: Built with specialist materials to withstand continuous subsea exposure.

• Compact and Robust Design: Easy to integrate into existing subsea systems without compromising durability.

• Customisation Options: Available in multiple pressure ranges and configurations to meet specific application requirements.

Why Choose an RS-485 Interface?

The RS-485 interface is an industry standard for digital communication, particularly valued for its ability to transmit signals over long distances without degradation. In subsea environments, where sensors are often located far from control units, this capability is essential.

The Subsea Pressure Transmitter with RS-485 Interface allows multiple transmitters to be connected on the same communication bus, reducing cabling costs and simplifying system integration. The digital interface also ensures that pressure readings are transmitted with greater accuracy and reduced susceptibility to electrical noise compared to analogue signals.

Applications of the PR3930 Subsea Pressure Transmitter with RS-485 Interface

The versatility of this transmitter makes it suitable for a wide range of industries and applications:

• Oil & Gas Exploration: Monitor subsea wellheads, pipelines, and risers.

• Renewable Energy: Support offshore wind, tidal, and wave energy installations.

• Subsea ROVs and AUVs: Provide critical depth and pressure data to remotely operated and autonomous underwater vehicles.

• Oceanographic Research: Deliver precise pressure data for scientific studies and environmental monitoring.

• Subsea Infrastructure: Support monitoring of underwater structures, pipelines, and cables.

Whatever the application, the Subsea Pressure Transmitter with RS-485 Interface ensures accurate, dependable results in even the most challenging environments.
