Kongsberg GT300C3G40V Marine Pressure Transmitter 0-40bar 4-20mA
I. Product Overview
The Kongsberg GT300C3G40V is a GT300 series marine pressure transmitter manufactured by Kongsberg, Norway. In the model number, "G" indicates gauge pressure measurement and "40" indicates a range of 0-40 bar. The transmitter is specially designed for general purpose pressure measurement in ship engine rooms, and can be widely applied for pressure monitoring of seawater, fresh water, lubricating oil, fuel oil and other media.
The GT300 series pressure transmitter can be mounted directly to the measuring point, or mounted in a bracket fixed to a bulkhead with a control valve below, providing flexible installation. The transmitter features standard 2-wire 4-20mA current output, supply voltage 24VDC (12-32VDC depending on load resistance), accuracy better than ±0.5% of full range, long-term stability better than ±0.2% FRO/year, delivering reliable performance.
The GT300C3G40V features 1/2" and 1/4" thread pressure connections, and electrical connection is made via an M gland on a DIN plug, providing reliable protection. The transmitter is suitable for various pressure measurement applications in ship engine rooms, and serves as a companion instrument of Kongsberg vessel automation and monitoring systems, widely applied on merchant vessels, offshore vessels and other ship types.
