Overview

The FT600 tuning fork level switch is a new type of level switch. The tuning fork is excited by a crystal to produce vibration. When the tuning fork is immersed in liquid material, the vibration frequency changes. This frequency change is detected by electronic circuits and outputs a switch value. The tuning fork level switch has no moving parts, so it does not require maintenance and adjustment. It is an upgraded product of the float level switch, which is used in the petrochemical, light industry, food, and water treatment industries to alarm and control the upper and lower limits of the liquid level.

Solid powders with good flowability in hazardous areas such as tap water, mineral water pulp, glue, dyes, wastewater, mud, and acidic and alkaline solutions that can produce gases, such as liquid beer, beer fermentation agents, and beverage diesel.

Product Features

●Strong adaptability: Different electrical parameters and densities of the tested liquid do not affect the measurement. Scaling, agitation, turbulence, bubbles, vibration, moderate viscosity, high temperature, high pressure and other harsh conditions have no effect on the detection

●No need for calibration: As the detection of tuning fork limit switches is not affected by the electrical parameters and density of the measured medium, no on-site calibration is required for any type of liquid being measured

● Maintenance free: As the detection process of the tuning fork limit switch is completed by electronic circuits without moving parts, it does not require maintenance once installed and put into operation
