Abstract : The patent describes a profiler for measuring ocean conductivity, temperature and depth which employs A.C. excited sensors with the ratio of each output signal to the input signal being indicative of the parameter being measured. Each sensor has an interface circuit which amplifies the output signal to a level sufficient to permit its transformation to a 16-bit signal by an analog-to-digital converter having a quadrature balancing provision that cancels the signal component caused by the A.C. excitation. The digital signals in frequency shift form are sent to the surface for processing.
