Extension Tube Vibrating Level Switch
Extension tube vibrating level switch is customized wetted area length by extended tube, the tuning fork design is very stable and unaffected by extension tube.
Extension Tube Vibrating Level Switch is customized wetted area length by extended tube .The position of the switching point can be determined by the length of the tube extension. The position of the switching point can be up to 2 m away from the installation site. The tuning fork design is very stable and unaffected by extension tube . The Extension tube vibrating level switch is ideal for use either in adhesive and abrasive products as well as in bulk solids with very low density.
Working Principle Of Vibrating Fork Switch:
The tuning fork vibrates at a resonant frequency through two piezoelectric crystals attached to its base, which is how the tuning fork level switch operates. The tuning fork’s frequency and amplitude will alter when the liquid level switch’s fork comes into touch with the medium. An intelligent circuit will detect and process these variations in the tuning fork’s liquid level switch, converting them into a switch signal.
