We product SU-YC is a newly developed Tuning Fork Liquid Level Switch, which is brought to its resonance frequency by means of piezoelectric crystals drive. If the tuning fork is covered by liquid, this frequency will change. The electronics of the SU-YC monitor the resonance frequency and then output a switching value.
“Tuning Fork Liquid Level Switch” can also be called “Electric Float”, it can be used when float level switch can be adopted and can not be adopted due to the reason of structure, turbulence, stir, bubble and vibration.
Main features:
◆Powerful adaptability: different electrical parameters and densities of the materials measured have no influence on the measurement. The extreme conditions, such as scale formation, agitation, onflow, bubbles, vibration, medium viscosity, high temperature and high voltage also make no difference on the detection.
◆Maintenance free: the detection procedure of the product is done by electronic circuit and there is no mobile component, thus it is maintenance free once being installed and put into service.
◆Adjustment free: the detection of the product is not influenced by electrical parameters and densities of the mediums measured, thus no adjustment on site is required no matter which liquid is measured.
