Operation range: 0 to 207 kPa (0 to 30 psia); approximately 0 to 9 m (0 to 30 ft) of water depth at sea level, or 0 to 12 m (0 to 40 ft) of water at 3,000 m (10,000 ft) of altitude
Factory calibrated range 69 to 207 kPa (10 to 30 psia), 0° to 40°C (32° to 104°F)
Burst pressure 310 kPa (45 psia) or 18 m (60 ft) depth
Water level accuracy* Typical error - 0.05% FS, 0.5 cm (0.015 ft) water
Maximum error - 0.1% FS, 1.0 cm (0.03 ft) water
Raw pressure accuracy** 0.3% FS, 0.62 kPa (0.09 psi) maximum error
Resolution < 0.02 kPa (0.003 psi), 0.21 cm (0.007 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
