SBE-3FSea-Bird ElectronicsThe SBE 3F is an enhanced version of Sea-Bird's proven SBE 3 temperature sensor. The superior performance of the SBE 3F results from its optimized electronic design, combined with an extraordinarily precise calibration procedure and quality testing program. The SBE 3F has a time response of approximately 0.07 second, an initial accuracy of 0.001 °C, and is typically stable to 0.002 °C per year. Every SBE 3F is calibrated in Sea-Bird's computer-controlled calibration baths. These super-low-gradient baths produce temperature calibrations with resolution and accuracy not previously available to oceanographers. These sensors can be successfully calibrated as separate modules, because they have built-in acquisition circuits and frequency outputs. When used with a CTD system, overall system accuracy is equal to the sensor accuracy degraded only by the uncertainty in the CTD's master clock. A typically small clock error of 1 ppm results in a temperature error of less than 50 µ°C. |
