Exceptional Performance

Glass-coated thermistor bead, pressure-protected in 0.8 mm diameter thin-walled stainless steel tube. Exponentially related to temperature, the thermistor resistance is the controlling element in an optimized Wien Bridge oscillator circuit. Resulting sensor frequency is inversely proportional to the square root of the thermistor resistance and ranges from approximately 2 to 6 kHz, corresponding to -5 to +35 °C.

Modular Sensor

Built-in acquisition circuits and frequency outputs; allows for calibration as separate modules.

Sea-Bird Calibration Quality

Individually calibrated in Sea-Bird’s computer-controlled, super-low-gradient calibration baths.
