DESCRIPTION

The SBE 16plus V2 (Version 2) SeaCAT Recorder measures temperature and conductivity (pressure optional) and provides high accuracy and resolution, reliability, and ease-of-use on moorings and other long-duration, fixed-site deployments. Compared to the previous 16plus, the V2 incorporates an electronics upgrade and additional features, with six differentially amplified A/D input channels, one RS-232 data input channel, and 64 MB FLASH memory. Data can be output in XML as well as ASCII and HEX formats. Firmware upgrades can be downloaded through the communications port, without opening the instrument.

The SBE 16plus V2 uses the same temperature and conductivity sensors (and optional strain gauge or Digiquartz^® pressure sensor) proven in 10,000 SeaCATs and MicroCATs. The unique internal-field conductivity cell permits the use of expendable anti-foulant devices, for long-term bio-fouling protection.

Calibration coefficients, stored in memory, permit data output in ASCII engineering units (degrees C, Siemens/m, decibars, salinity [PSU], sound velocity [m/sec.], etc.). The sample interval, ranging from 10 to 14,400 seconds, is user-programmable in 1-second increments. Between samples, the SBE 16plus V2 powers down, drawing only 20 microAmps. Nine alkaline D-cells provide power for 355,000 samples of C and T. Conditioned power (500 mA) is available for auxiliary sensors (dissolved oxygen, turbidity, fluorescence, PAR, etc.). Data is recorded in memory for 38.4K baud upload after recovery.

Real-time monitoring is practical using the SBE 16plus V2 3-wire RS-232C data output. The 16plus V2 is well suited to networked sensor arrays where its operation can be triggered by satellite, radio, or hardwire telemetry equipment. An optional inductive modem (1-wire loop) interface allows multiple SeaCATs to share a simple and robust telemetry cable.
