Research-quality conductivity-temperature sensors for mobile marine platforms


The NBOSI CT Sensor is a highly accurate internal field, four-electrode conductivity cell with an integral pressure-protected thermistor and a self-referencing electronics board. The patented free-flushing design is quiet, vibration-free and insensitive to mounting location or electrode fouling.

The sensor is available in a cabled/connectorized version or with a thru-hull penetrator for direct hull mounting. Sensors are fully potted and capable of operation to at least 6000 dbar. On request we can perform in-house pressure validation testing to 10,000 psi. An optional pressure sensor enables measurement of ocean density and sound speed.

  • Cabled CT Sensors mount anywhere and are available in a range of cable lengths and connector types to fit your platform requirements

  • Hull-mount CT Sensors are directly through-hull mounted using a custom-engineered penetrator
