ABSTRACT:
An instrument for measuring electrical conductivity of a liquid comprises a two-electrode probe for insertion into the liquid. A triangular waveform generator (IC4 and IC5) impresses a voltage of fixed amplitude on one electrode of the probe by means of driver circuitry (IC3). This voltage drives an electric current through the liquid to the other electrode of the probe. Receiver circuitry (IC6) detects the current at this other electrode, and converts the detected current to a triangular wavefore AC voltage signal. Amplifier circuitry (IC1) amplifies the output of the receiver circuitry, and the amplified voltage signal is converted to a smoothed DC voltage signal by precision rectifier circuitry (IC2 and IC7). The output of the precision rectifier circuitry is processed to obtain a signal indicative of electrical conductivity of the liquid.
