U20-001-02-TI Titanium for Temp & Water Level for Salt Water (0 to 30 m)

Pressure Sensor
Operation range: 0 to 400 kPa (0 to 58 psia); approximately 0 to 30.6 m (0 to 100 ft) of water depth at sea level, or 0 to 33.6 m (0 to 111 ft) of water at 3,000 m (10,000 ft) of altitude

Factory calibrated range: 69 to 400 kPa (10 to 58 psia), 0° to 40°C (32° to 104°F)

Burst pressure: 500 kPa (72.5 psia) or 40.8 m (134 ft) depth

Water level accuracy*: Typical error - 0.05% FS, 1.5 cm (0.05 ft) water

Maximum error: - 0.1% FS, 3 cm (0.1 ft) water

Raw pressure accuracy**: 0.3% FS, 1.20 kPa (0.17 psi) maximum error

Resolution: < 0.04 kPa (0.006 psi), 0.41 cm (0.013 ft) water

Pressure response time 90%: < 1 second

Thermal response time (90%)†: Approximately 10 minutes in water to achieve full temperature compensation of the pressure sensor

* With accurate reference water level measurement and Barometric Compensation Assistant data

** Absolute pressure sensor accuracy includes all pressure drift, temperature, and hysteresis-induced errors

† Maximum error due to rapid thermal changes is approximately 0.5%.

Temperature Sensor
Operation range: -20° to 50°C (-4° to 122°F)

Accuracy: 0.37°C at 20°C (0.67°F at 68°F),

Resolution: 0.1°C at 20°C (0.18°F at 68°F) (10-bit),

Response time (90%): 3.5 minutes in water (typical)

Stability (drift): 0.1°C (0.18°F) per year

Logger
