What is the KONGSBERG GT403 Pressure Transmitter?

The GT403 is a precision pressure transmitter that measures hydrostatic pressure generated by liquids inside marine tanks.

By continuously measuring pressure at the bottom of a tank, the transmitter enables the automation system to determine:

  • Tank Level
  • Tank Volume
  • Cargo Quantity
  • Ballast Quantity
  • Fuel Consumption Data
  • High and Low Tank Alarms
  • Stability Management Information

The GT403 is designed to provide long-term stability, excellent accuracy, and reliable performance even under severe shipboard operating conditions.

Working Principle

The GT403 operates by measuring hydrostatic pressure generated by the liquid column above the sensor.

As the liquid level changes, the pressure applied to the sensing element changes proportionally. The transmitter converts this pressure into an electrical signal which is transmitted to the vessel's tank gauging computer.

The control system then calculates:

  • Liquid Level
  • Tank Volume
  • Remaining Capacity
  • Cargo Quantity
  • Ballast Quantity
  • Alarm Conditions

This information is displayed in the Cargo Control Room, Engine Control Room, or Integrated Automation System.


Main Components

Pressure Sensing Element

The core measuring component that detects hydrostatic pressure.

Stainless Steel Process Connection

Provides secure mounting to the tank installation point.

Electronic Conversion Module

Converts pressure values into electrical output signals.

Signal Cable Assembly

Transfers measurement data to the monitoring system.

Protective Housing

Protects internal electronics from moisture and mechanical damage.
