Ultrasonic solid state liquid level switch can directly replace the mechanical float type liquid level device. The switch uses proven ultrasonic technology and solid-state integrated electronics to operate reliably in virtually any liquid without being affected by stickiness.
Ultrasonic solid state liquid level switch can directly replace the mechanical float type liquid level device. The switch uses proven ultrasonic technology and solid-state integrated electronics to operate reliably in virtually any liquid without being affected by stickiness. This eliminates stickiness problems and failure rates due to the limited mechanical life inherent in mechanical float design. The complete epoxy-sealed electronic components combined with ultrasonic sensing technology enable years of maintenance-free operation.
