The Static and Dynamic Calibration Method of a Pressure Sensor

The correct measurement of a ship's hydrodynamic signature is important because the measured values of the ship's hydrodynamic field are an indication of the estimated level of susceptibility of the ship to an underwater explosion initiated by the trigger level of pressure influence channel of sea mines. The calibration of the hydrodynamic channel is therefore an important element in measuring technology and is required for the measurement equipment used to measure the pressure signatures of military ships. The article presents the successive stages of calibration: hydrodynamic sensor in laboratory and industrial conditions, hydrodynamic channels in conditions on land or on board of the measurement ship and in water, in a test tank as well as in real sea conditions. The description includes methods of static and dynamic tests.
