Level Transmitter Dealers in Ram Bagh, Indore

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.
