1. Working
Principle
Based on the principle of conductance, use the probe of the
material instrument and the container wall as the two pole plates
of one capacity. When the level of material between the probe and
the container falls up and down, the capacity and the total
resistance will change in proporation to it. The specific analyzing
and contrast electric circuit will calculate this change and
convert it into 4~*0mA current signals through the amplifier and
thus further detect the level of material.
