The SBE 37-SI MicroCAT is a high-accuracy conductivity and temperature (pressure optional) sensor with Serial Interface, which includes a non-volatile FLASH memory.
Sea-Bird ElectronicsThe SBE 37-SI MicroCAT is a high-accuracy conductivity and temperature (pressure optional) sensor with Serial Interface, which includes a non-volatile FLASH memory. Externally powered, it is useful as a stand-alone monitoring device, and is easily integrated with current meters, ROVs, AUVs, towed sonars, and other instrumentation platforms. Constructed of non-corroding materials to ensure long life with minimum maintenance, the MicroCAT is rated for operation to 350 meters (plastic ShallowCAT housing) or 7000 meters, or pressure sensor full-scale range.
Calibration coefficients are stored in EEPROM, allowing the MicroCAT to output data in ASCII engineering units (decimal or XML format); raw output is also available. Data always includes Conductivity, Temperature, and (optional) Pressure; time, sound velocity (Chen-Millero), salinity, depth, and density can also be output.
