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.
L(high) L(low) = C(high) C(low) / P × {ε(material) ε(air)}


device creates a chart of level to 4-20mA translation.
