We are offering capacitance level transmitter.
Working principle
the probe forms a capacitance with the metallic tank-wall.
The capacitance is sum of three capacitance :-
c(air)=ε(air) × p × (h - l)
c(material)=ε(material) × p × l
c(residual) is due to device itself.
where ε(air) is the dielectric constant of air ≈1.
Ε(material) is dielectric constant of material.
p is constant of probe and installation, h is the active length
of probe and l is the level of material.
capacitance to level translation is performed with the aid of
on-site calibration also called "wet-calibration"
the device stores a low level capacitance as level for 4ma and
high level capacitance as level for 20ma as defined by the user.
using these values and following equation.
c(high) c(low)
l(high) l(low) = ------------------------------
p × {ε(material) ε(air)}
device creates a chart of level to 4-20ma translation.
