Product Description

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.
