Absolute Pressure | Measurement Range: 0 to 145 kPa (0 to 21 psia) Factory Calibrated Range: 69 to 145 kPa (10 to 21 psia) @ 0°C to 40°C (32°F to 104°F) Burst Pressure: 310 kPa (45 psia) or 18 Meters (60 ft) Depth Raw Pressure Accuracy* (W-CTD-04): Maximum Error - ±0.3% FS, 0.43 kPa (0.063 psi) Pressure Response Time**: <1 Second to 90% at a Stable Temperature * Raw Pressure Accuracy: Absolute Pressure Sensor Accuracy includes All Sensor Drift, Temperature and Hysteresis-Induced Errors. ** Changes in Temperature: Allow 20 Minutes in Water to Achieve Full Temperature Compensation of the Pressure Sensor. There can be up to 0.5% of Additional Error due to Rapid Temperature Changes. |
Water Level | Measurement Range: 0 to 4 Meters (0 to 13 ft) of Water Depth at Sea Level or 0 to 7 Meters (0 to 23 ft) of Water at 3,000 Meters (10,000 ft) of Altitude Accuracy*: Typical - ±0.075% FS, 0.3 cm (0.01 ft) Water; Maximum - ±0.15% FS, 0.6 cm (0.02 ft) Water Resolution: <0.014 kPa (0.002 psi), 0.14 cm (0.005 ft) Water * Water Level Accuracy: With Accurate Reference Water Level Measurement, Known Water Density, and a Stable Temperature Environment. System Water Level Accuracy Equals the Sum of the Barometric Water Level Accuracy Plus the Selected CTD Sensor Water Level Accuracy. |
Temperature | Measurement Range: -20°C to 50°C (-40°F to 122°F), Non-Freezing Water Accuracy: ±0.15°C (±0.27°F) from 0°C to 50°C (32°F to 122°F) Resolution: 0.01°C at 25°C (0.018°F at 77°F) Response Time: 3 minutes to 90% in Water (Typical) Drift: <0.1°C (0.18°F) per Year |
