R&D: Hydrophones and Preamps Calibration of 40 hydrophones using the NATO water tank (1 bar) Hydrophone + preamp (+ 38 dB gain) Radiation lobe 30 kHz 50 kHz Giorgio Riccobene, LNS-INFN VLVnT 2009, Athens October 13 –15 ,2009
R&D: Hydrophones and Preamps Pressure calibration of 40 Hydrophones using the NATO pressure tank Set-up for high pressure tests: measurement of relative sensitivity losses Relative Hydrophone sensitivity variation with hydrostatic pressure at 20 kHz • Hydrophone placed in pressure vessel filled with oil and immersed in a calibration tank • A projector (ITC1042) is placed at approximately 1 m from the pressure vessel 300 Bar 400 Bar • Pressure is increased to 400 bar and allowed to settle for 30 minutes. • Hydrophone signal is acquired at 400, 300 and 50 bar. Measured variations ≤ ±1 dB Giorgio Riccobene, LNS-INFN VLVnT 2009, Athens October 13 –15 ,2009
