Onset MX2001-03-SS-S Water Level Sensor (76m, 250ft)

Pressure (Absolute) and Water Level Measurements:

  Operation Range: 0 to 850 kPa (0 to 123.3 psia); approximately 0 to 76.5 m (0 to 251 ft) of water depth at sea level, or 0 to 79.5 m (0 to 262 ft) of water at 3,000 m (10,000 ft) of altitude

  Factory Calibrated Range: 69 to 850 kPa (10 to 123.3 psia), 0° to 40°C (32° to 104°F)

  Burst Pressure: 1.200 kPa (174 psia) or 112 m (368 ft) depth

  Water Level Accuracy: Typical error: ±0.05% FS, 3.8 cm (0.125 ft) water; Maximum error: ±0.1% FS, 7.6 cm (0.25 ft) water
