Đầu dò mức HE-4H-S Hitrol Electrode Type Level Switch

HE Series is an Electrode Type Level Switch, used for limit detection in a tank containing electrically conductive liquids. Limit levels can be determined by using one instrument with multi-probe rods. The rod length depends on the position of the level to be monitored and/or on whether a filling / empty function is required.

PRINCIPLE

This technique is based on the conductivity difference between various materials. Air, for example, has very low conductivity and water in general has a very high conductivity. A low alternating voltage is applied between the electrodes. When the filling liquid reaches the electrode, a small alternating current flows, control unit produces a signal output after detecting of this alternating current.

APPLICATION

● Brewery Plant
● Washing Plant
● Syrup
● Water
