It comes with a pre-amplified output of 0 to 35 dB (selectable on order) with current or voltage signalling. It has a diameter of 33 mm and length of 199 mm (single package). It is depth-rated to 2500 m and can operate at temperatures between -40 and +70 degC. Its nominal voltage sensitivity without pre-amp is -200 +/- 1.5 dBV re 1uPa. Its band pass is 5 Hz HPF, no LPF installed (unless otherwise specified), and current draw is 1.3 mA at 6.8 VDC, or 4.2 mA with pre-amp."@en ; sdo:inDefinedTermSet ; sdo:name "GeoSpectrum M36-100 hydrophone"@en ; sdo:termCode "SDN:L22::TOOL1661" .
