Abstract

PURPOSE: To keep fixed minute current flow constantly in a measuring circuit by using a constant current power supply circuit to turn the leectric resistance of the oil film of a rolling object to a voltage value and measure the resistance value conversely from the changes in said voltage, thereby obtaining the oil film resistance.
