Abstract

Occurrence of scale and slime in closed systems for industrial water frequently causes trouble. To avoid such trouble, we are trying to develop sensitive sensor systems constructed with piezoelectric quartz crystals for the earliest detection of scale and slime. The proportional relationship between weight gain on the electrode's surface of the crystal and decrease of the oscillation frequency is well-known. However, it is very difficult to stabilize the oscillation frequency in such an environment as salt-containing water. In this study, we can keep the frequency stable by controlling the voltage imposed on the oscillation circuit. Using this ingenious sensor system in test plants, we can achieve favorable results in the detection and measurement of scale and slime.
