Vibrating Fork Level Switches
Vibrating Fork Level Switches are suitable for virtually all liquid applications.Vibrating fork level switches utilize a piezoelectric-driven tuning fork that exhibits a large change in resonant frequency when immersed into a liquid or bulk solid process.
A smart microprocesso-based electronic unit keeps the sensor in a resonant state as it changes from dry to wet or wet to dry. An important feature of this switch is that its resonant frequency is not significantly affected by coating on the fork until the space between the forks is bridged. Features include a complete range of process connections, wide choice of housing and wetted parts materials, four different switching functions, extended fork lengths, hazardous area, basic self-checking functionality, and overfill approvals.Applications include redundant high or low process levels without concern for parameters, such as specific gravity, dielectric constant or mounting position of the sensor.
