The CS547A probe monitors the electrical conductivity (EC) and temperature of water. EC is measured with three cylindrical stainless-steel electrodes mounted in an epoxy housing. The electrode configuration eliminates ground loop problems associated with sensors in electrical contact with earth ground. The electrodes are ac coupled, and a bipolar excitation is applied. This reduces electrochemical reactions, minimizes corrosion, and extends the probe’s life. Temperature is sensed with a thermistor.
