LMC : Capacitance Level Limit Switch for Solids and Liquid

Applications :
Water, waste water, cereals, beans, edible oil process, animal feed, rice plants,
soya plants, dye powder, chalk, gypsum, fly-ash, cement, sand, plastic granules,
spices, milk powder,


Principle :
Capacitance type limit switch is a static level sensor, Its sensing parts are: Earth and Sensing Rods.
The capacitance is formed by the sense rod and earth extension.
When no material is present, the capacitance is analogically a multiple of probe dimension and dielectric
constant of air . When material is present, the capacitance gets multiplied by dielectric constant
of the material. This variation in capacitance is then translated into switching output by the device.
