ABSTRACT:
A probe for measuring electrical conductance to determine water concentration in a fluid is disclosed. The probe comprises a pair of spaced apart electrodes and a bridge of protein gel between the electrodes. The probe is especially useful for monitoring water concentration in the lubrication oil for a compressor drive train of a hermetic vapor compression refrigeration system. In such a refrigeration system the water concentration in the lubrication oil corresponds to water concentration in the refrigerant of the refrigeration system.
