Onset MX2001-02-SS-S Water Level Sensor (30m, 100ft)

Pressure (Absolute) and Water Level Measurements:

  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, 3.0 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 at a stable temperature
