Externally powered, high-accuracy instrument, designed for shipboard determination of sea surface (pumped-water) conductivity and temperature.
Salinity and sound velocity can also be computed.
Constructed of plastic and titanium to ensure long life with minimum maintenance.
Communication with the MicroTSG is over an internal, 3-wire, RS-232C link, providing real-time data transmission. Commands can be sent to the MicroTSG to provide status display, data acquisition setup, data display and capture, and diagnostic tests. User-selectable operating modes include:
Calibration coefficients stored in EEPROM allow the MicroTSG to transmit data in engineering units.
The MicroTSG retains the temperature and conductivity sensors used in the SBE 21 Thermosalinograph, but has improved acquisition electronics that increase accuracy and resolution, and lower power consumption. The MicroTSG’s aged and pressure-protected thermistor has a long history of exceptional accuracy and stability (typical drift is less than 0.002 °C per year). Electrical isolation of the conductivity electronics eliminates any possibility of ground-loop noise.
The MicroTSG’s internal-field conductivity cell is unaffected by external fouling, and uses expendable anti-foulant devices.
