The Resonator utilizes a piezoelectric driven tuning fork that exhibits a large change in resonant frequency when immersed in any liquid. A "smart" microprocessor-based electronic unit keeps the sensor in a resonant state as it changes from dry to wet or wet to dry.
The resonant frequency is continuously monitored for changes created by a wet or dry sensor and an alarm is provided via relay. The RS85 should be used when the application requires optional process connections, exotic materials of construction, coatings, finishes or adjustable time delay and density set point.
