Benefits
- high accuracy characteristics over the entire operating temperature range up to 0.08% over the entire pressure measurement range, including the initial section
- high resolution
- sealed converter connector
Scope
- autonomous uninhabited underwater vehicles, including gliders
- air-cavity vessels, ekranoplans (WIGs)
- water level measurements in wells, tanks, etc.
Principle of Operation
The display shows simultaneously the pressure information from 4 transducers with a sequential survey of all transducers. With external power supply for pressure transmitters, up to 31 transmitters can be connected to the control unit.
