Abstract : The patent relates to an expandable depthometer which is electrically coupled to a pressure sensitive transducer element disposed in a marine environment. The transducer, excited by a power supply, feeds a signal, which is proportional to the depth, back to the depthometer console. A reference level signal is created across a variable resistor to produce a zero reading at selectable datum depth. A full-scale selector switch is positioned to switch in a particular impedance branch to establish a range of operation from a reference-datum level as predetermined by the reference level signal. A single readout meter is capable of showing incremental depth variations of as little as 10-feet to as much as 100-foot increments, in depths in excess of ten-thousand feet.
