A corrosion detector for use in detecting corrosion currents in the form of AC and DC leakage currents which occur in a marina. The detector monitors AC power and ground lines or other conductive lines interconnected between boats in a marina and includes a transducer to detect leakage currents which occur in the boats connected to the power lines. The detector provides either an alarm signal or displays the damage rate and location to indicate corrosion currents in one or more of the boats in a harbor.

Corrosion detector

A thermocouple linearizer circuit for use in a device for digitally displaying the temperature of a thermocouple. The circuit includes a plurality of proportional correction means, each connected to receive a non-linear electrical signal representing the temperature of a thermocouple. The correction circuits generate a correction signal proportional to the difference between a non-linear electrical signal and a predetermined reference signal. The correction signals are initiated when the non-linear signal exceeds the respective reference signal in each correction circuit. An arithmetic unit is included for adding the correction signals and the non-linear signal thereby forming a signal corresponding to a linear function of the temperature of the thermocouple.
