Kongsberg GT404D4H25T Marine Pressure Transmitter
I. Product Overview
The Kongsberg GT404D4H25T is a GT404 series marine pressure transmitter from Kongsberg Maritime (formerly Autronica), specifically designed for cargo line pressure measurement on ships. This pressure transmitter features a sealed gauge design with a 59mm aperture diaphragm unit. The diaphragm is made of AISI 316 stainless steel and coated with Teflon, providing excellent corrosion resistance and anti-fouling capability, able to adapt to complex media environments such as cargo oil and chemicals.
The GT404D4H25T has a measuring range of 0.6 to 40bar with an accuracy of 0.90%FRO. The output signal is 4-20mA superimposed with HART communication protocol, facilitating integration with ship automation systems and cargo monitoring systems. The transmitter features a temperature compensation range of 0-60°C, temperature drift less than 0.01%FRO/°C, and long-term drift less than 0.3%/year, ensuring long-term stable operation in harsh marine environments. The product is certified with Ex ia IIC T4 intrinsic safety explosion-proof and has IP68 protection rating, allowing direct installation in hazardous areas such as cargo tank areas. Widely used in cargo system pressure monitoring on oil tankers, chemical tankers, LNG carriers and other ships, as well as pressure measurement on offshore engineering platforms.
