Replacing a PCB instrument is just as important as replacing the UTI sensor itself. The PCB instrument is responsible for processing measurements from the sensor and displaying accurate cargo tank information. Selecting the correct compatible replacement ensures reliable operation while avoiding unnecessary downtime.

This guide explains how to choose the right compatible PCB instrument for your vessel’s UTI tank gauging system.

The PCB instrument is the electronic unit used together with the UTI sensor. It receives signals from the sensor and displays measurements such as ullage, interface level and temperature depending on the installed system.

Because different manufacturers use different electronics and connectors, PCB instruments are generally designed for specific UTI systems.

Before ordering a replacement PCB instrument, identify the UTI system currently installed on board. Common systems include:

• GTEX®
• MK3®
• MMC®
• TFC-02®
• Marsen®
• Seahover®

Each system requires a compatible PCB instrument designed for that particular platform.

One of the easiest ways to identify the correct replacement is by examining:

• Cable connector type
• Sensor connection
• Existing instrument model
• Equipment identification label

Matching these details helps ensure compatibility with your existing installation.

If both the PCB instrument and sensor are heavily worn or have experienced years of service, replacing them together can improve long-term reliability.

Many operators choose to replace both components during scheduled maintenance to minimise future downtime.

A quality compatible PCB instrument should provide:

• Reliable measurement performance
• Compatibility with the installed UTI system
• Robust construction suitable for marine environments
• Straightforward installation without modifying existing equipment

Selecting the correct compatible model helps maintain normal cargo gauging operations while reducing replacement costs.

If you are unsure which PCB instrument your vessel requires, UTISpares can help identify the correct compatible replacement.

Simply send:

• A photograph of the existing PCB instrument
• A photograph of the sensor
• The equipment nameplate (if available)
• Vessel details or previous maintenance records

Our team will recommend the correct compatible replacement for your UTI system.
