Background & TECHNOLOGY

Beginning in the late 1950's Neil Brown developed methods to determine ocean salinity in real-time using measured seawater conductivity and temperature. This pioneering work eventually resulted in the first modern conductivity-temperature-depth (CTD) sensor.

The NBOSI approach to measuring salinity is an evolution of Neil Brown's patent (US 6,720,773) for an internal field, four-electrode conductivity cell with an integral pressure-protected thermistor and efficient, self-referencing electronics.

Optimized for use on mobile platforms, the NBOSI CT Sensor is free-flushing, fast-responding, quiet, vibration-free, rugged, low-power and insensitive to mounting location. Unlike existing two-electrode cells, the NBOSI Sensor not require an energy-consuming and noisy pump. And unlike inductive cells, our compact, rugged, and low-drag sensor may be mounted anywhere on the vehicle without compromising data quality or sacrificing hydrodynamic efficiency.

All NBOSI sensors use 99.95% pure platinum electrodes and are fully epoxy potted and capable of operation beyond 6000 dbar. We regularly perform in-house pressure validation testing to 9,800 psi (6750 dbar) for customers operating under extreme conditions.

All products are assembled and calibrated in our Massachusetts, USA facility.

Miniaturized precision electronics combined with a compact and rugged sensor body deliver real-time, research-quality conductivity-temperature-depth (CTD) measurements in a package that is easy to integrate and maintain.

Each sensor is constructed with a user-specified permanently attached cable pigtail or bulkhead connector. See product configuration matrix for available options or contact us for a custom solution.

Available with or without an integrated  Keller PA7LD pressure sensor with 30, 100 or 200 bar range. With an installed pressure sensor the 500 Series CTD can provides real-time ocean density and sound speed output.

Specifications Product configuration matrix
Our original conductivity-temperature (CT) sensor consists of an externally-mounted CT cell and an internally-mounted precision electronics board.  

Available in  rectangular and cylindrical form factors to suit your application. Connect via cable with a user-specified connector. See product configuration matrix for available  options.
