THEORY & STRUCTURE

Work theory of tuning-fork material level switch is through the installation of a pair of pressure in the tuning-fork base seat ,transistors make the tuning fork vibrate in a certain common frequency .When measured materials cover a tuning-fork vibration reduce,the changed vibration frequency is automatic to know,the handled signal adjust relay,achieve the purpose of instruct or control.

CHARACTERISTICS

●Strong adaptability–different electrical parameters and density of the tested have different effect on measuring.Scaling,agitation, turbulence, bubble, vibration, medium viscosity, high temperature and high pressure,this bad conditions have no effect on checking.
●Free from maintaining–because the checking process of tuning fork limit switch acomplished by electronic circuit,no moving parts,so once installed and put into operation will not need to maintain.
●Without calibration–because the checking process of tuning fork limit switch not under the influence of the tested medium electric parameter and density,so no matter measure which liquid,scene calibration do not need。
