Description
The tuning fork level switch alkyc-160 is a general level switch. The tuning fork is excited by piezoelectric crystal to produce vibration. When the tuning fork is immersed in liquid or solid, the vibration frequency changes. This frequency change is detected by the electronic circuit and outputs a switch value. It is widely used in petrochemical, metallurgy, light industry, building materials and other industries.
Tuning fork type liquid level switch" is also known as "electric float". The "tuning fork type liquid level switch" can be used when the floating ball limit switch is used or when the floating ball level switch cannot be used due to structure, turbulence, agitation, bubbles and other reasons.
characteristic:
Strong adaptability - different electrical parameters and density of the tested material have no influence on the measurement. Scaling, agitation, turbulence, bubbles, medium viscosity, high temperature, high pressure and other adverse conditions have no effect on the detection.
Maintenance free - since the detection process of the tuning fork limit switch is completed by the electronic circuit and there are no moving parts, maintenance is not required once it is installed and put into operation.
No need to adjust - because the detection of the tuning fork limit switch is not affected by the electrical parameters and density of the measured medium, no matter what kind of liquid is measured, it does not need to be adjusted on site
