Tuning fork liquid level/material level switch

FS300 series tuning fork level switch is a new type of level switch. The tuning fork is excited by the crystal to generate vibration. When the tuning fork is immersed in the material, the vibration frequency changes. This frequency change is detected by the electronic circuit and outputs a switch value. The tuning fork type level switch is also called "electrical float". The "fork type level switch" can be used wherever the float level switch is used and the float level switch cannot be used due to structure, turbulence, agitation, air bubbles, vibration and other reasons. Level switch" Since the tuning fork level switch has no moving parts, it does not need maintenance and adjustment. It is an upgraded product of the float level switch. Tuning fork level switches are widely used in petrochemical, light industry, food, water treatment and other industries to perform upper/lower limit alarm and control on material level.

Features
1. Strong adaptability: not affected by medium disturbance, electrical parameters, solid gas composition and foam. Scale, agitation, turbulence, air bubbles, vibration, medium viscosity, high temperature, high pressure and other harsh conditions will not affect the detection.
2. Free from maintenance: Since the detection process of the tuning fork limit switch is completed by an electronic circuit, there are no moving parts, and it is safe and reliable, so no maintenance is required once it is installed and put into operation.
3. No need to adjust: Since the detection of the tuning fork limit switch is not affected by the electrical parameters of the measured medium, no on-site adjustment is required no matter what kind of liquid is measured.
4. It is suitable for the measurement of liquid, powder and small particle solid.
