Environmental sensor manufacturer Valeport has confirmed that Ocean Business 2023 will be the launch venue for its SWiFT Deep CTD, a new addition to the company’s range of SWiFT profilers, designed for those requiring CTD measurements to depths of 6,000m.
Also featuring on the company’s stand is its recently launched Bathy2, a tool that the company believes will revolutionize the collection of bathymetric data, alongside four further releases which are all designed with ease of use at their core, where an improved user experience is now available alongside high quality, precise data.
The new SWiFT Deep CTD provides survey-grade sensor technology coupled with the convenience of Bluetooth wireless technology, rechargeable battery and an integral GNSS module to geo-locate each profile.
Using Valeport’s high accuracy sensor technology to combine sensors for multiple profiles in a single drop, the SWiFT Deep CTD can operate to 6,000m, delivering directly measured conductivity, temperature and depth. In addition, the SWiFT Deep CTD will provide computed salinity, density and sound velocity, calculated using the UNESCO international standard algorithm and Chen and Millero equation.
The recently launched Bathy2 integrated sensor suite is designed to meet customer bathymetric requirements for a reliable, accurate and robust instrument with more functionality to suit specific operations up to 6,000m in depth. 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 evolution 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.
According to Valeport, improving the user experience has been a key driver in the development of this superior bathymetric instrument and the addition of a 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. 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.
The smart miniIPS2 underwater pressure sensor has an accuracy to 0.01% to offer a cost-effective solution to vehicle pilots who require highly accurate depth information in real time.
This innovative pressure sensor, with a unique interchangeable pressure module, allows the user to quickly and easily change the pressure transducers whilst in the field, with no tools required, to maximize operational specific depth requirements.
The compact uvSVX is designed for underwater vehicles where space is at a premium and it delivers calculated salinity and density data, along with SVP as standard. Like the miniIPS2 it also features field-swappable sensor heads, has a depth rating of 6,000m and delivers 0.01% accuracy. The interchangeable pressure transducer, with integral calibration is easily changed in a couple of minutes without opening the instrument and is available in 10, 20, 30, 50, 100, 200, 300, 400 and 600bar variants.
The SWiFT CTD profiler provides enhanced accuracy and versatility for those requiring CTD measurements. The SWiFT CTD profiler, like the newly released ‘Deep’ version, provides survey-grade sensor technology combined with the convenience of Bluetooth wireless technology, rechargeable battery and an integral GPS module to geo-locate each profile.
Valeport’s technology delivers sensors for multiple profiles in a single drop. The SWiFT CTD features a new fast response temperature probe and operates down to 500m as standard. With an operational battery life of up to five days and the convenience of charge via USB, the SWiFT CTD is intended for offshore, coastal, harbor and inland environmental and hydrographic survey use. A CTDplus version is currently available with an option for Turbidity, as well as Chlorophyll a option. The SWiFT CTDplus Turbidity combines CTD measurements and Turbidity observations, in addition to providing computed Salinity, Density and Sound Velocity. The SWiFT CTDplus Chlorophyll a delivers combined CTD measurements and fluorometry observations.
