Application and features

Suitable for measuring medium-density solid powders or granules that can flow freely. Also suitable for almost all liquid media, this series of tuning fork level switch can measure a variety of level, with high/low failure safety limit switch, overflow or dry run protection, pump control, showing the presence/absence of flow in the pipeline, etc. Features.

Tuning fork switch can measure a variety of level, with high / low failure safety limit switch, overflow or air running protection, pump control, display pipe with / without flow and other functions.

Tuning fork switches are mainly used for challenging liquids, including layers, contaminated waste water and hydrochloric acid, and industrial liquids such as sodium hydroxide.

The tuning fork switch has a variety of output formats, 2-wire AC, 2-wire DC, and 3-wire PNP/NPN transistors. The operation of the tuning fork level switch is independent of the conductivity, dielectric constant, viscosity, pressure and temperature of the liquid.
