Bathy2 - The latest evolution in bathymetric measurement
The Bathy2 is designed to meet customer bathymetric requirements for a reliable, accurate and robust instrument with more functionality to suit specific operations up to 6000m in depth.
Bathy2 - Density corrected depth data directly from one instrument
An enhancement of the popular Midas BathyPack, the new Bathy2 uses state-of-the-art sensors to generate Sound Velocity and Density profiles for precision depth and height data.
This new instrument brings together the benefits of density corrected output directly from one instrument, alongside the flexibility of third-party pressure sensor input and Valeport interchangeable pressure modules to allow users enhanced accuracy at different depths.
Improved user experience
Improving the user experience has been a key driver in the development of this superior bathymetric instrument and the addition of dedicated data output for INS allows bathymetric data to be efficiently communicated directly with users’ own operational software.
Other helpful benefits include the flexible pressure options using Valeport’s interchangeable pressure sensors, these field-swappable sensor heads make it easy for users to select the correct pressure for their working depth bringing benefits of exceptional reliability and a higher degree of accuracy.
Designed for surveyors requiring bathymetric data from underwater vehicles
Designed for surveyors requiring bathymetric data from ROVs, underwater vehicles or drop structures, Bathy2 also has an external pressure sensor input option for Digiquartz referencing. This comprehensive bathymetric package offers other useful parameters such as Altitude and Bathy2 interfaces with the Valeport VA500 altimeter and other popular third party makes.
Seamless data transfer
Data transfer is via Ethernet or RS232/RS485 interfaces and the Bathy2 Interpreter function via the Valeport Configure software allows data out on extra ports in industry-standard formats, this facility also allows for an atmospheric pressure data input.
Type: High accuracy and interchangeable, temperature compensated piezo-resistive sensor. Delivers the performance previously only available from a resonant quartz sensor. It also brings the added advantages of long-term stability, allowing longer intervals between calibration, and a smaller and more robust construction; complex and vulnerable arrangements of diaphragms and oil filled capillaries & reservoirs are therefore no longer necessary.
