The Autronica GT403 is a Pressure Transmitter that is designed to be submersed in ballast and service tanks to measure the level. Other types of the GT403 can be used to measure pump pressure on submerged ballast pumps, or on other submerged equipment. The Autronica GT403 is available as an absolute type or a sealed gauge type.
The Autronica GT402 Transmitter consists of a piezo resistive sensing element together with an electronic unit that is encapsulated in the sensor body. The body is made out of titanium so it can be used in a submerged installation.
