SU-YC Tuning Fork Level Switch of Liquids

详情

Fundamental principles The tuning fork of SU-YC is a kind of universal liquid level switch, which is brought to its resonance frequency by means of piezoelectric crystals drive. If the tuning fork is covered by liquid or solidity, this frequency will change. The electronics of the SU-YC monitor the resonance frequency and then output a switching value, in this way, to alarm and control the liquid level. The structure and characteristics of tuning fork liquid level switch make it can replace any level switch of other principles, and can be widely used in building materials, petroleum, chemical industry, light industry, metallurgy field to alarm or control the height of liquid level for their lower and upper limit.    Qualification Power Supply AC **0V *0Hz / DC *4V Operating Temperature fork ******0°C                                          Instrument *****0°C Operating Pressure ≤2MPa Fluid density  0.6g/cm3 (in minimum) Action point Vertically insert into water about *5mm Start up time  about 3 sec Response time about 1 sec Output style One set of relay contact (AC **0V/3A, DC *0V/ 3A) Output delay time  ***0sec, can be adjusted Sensitivity  *0 grades can be set Consumption ≤1W Process Connection R 1 Taper Pipe Thread
