Vibrating Fork Switch FT-50

*The Vibrating Fork Switch is designed to enable secure point level measurements as well as high and low level alarms to prevent overfill;
*The vibrating fork technology realize identify the difference of liquid by resonance principal, resonant period is in proportion to the density of liquid;
*When the forks come in contact with a liquid, the resonant period difference between the liquid and air is detected and the device switches and alarms.
