HT-100C-2 Series is a 2-wire level transmitter installed in a tank or other container within the tank contents (liquid) which has a permittivity of the contents of the container continuously measure the height of container content convert to output signal (DC 4 ~ 20mA) .
HT-100C-2 Series is compact type.
PRINCIPLE
The basis of this technique lies in the physical properties of a capacitor. The capacitance of a capacitor is derived from the distance between the electrodes the surface area A of the electrodes and the interposing dielectric E.
The vessel wall and the probe from the two electrodes. The distance between the electrodes and surface area remain constant. The only variable is the depth of material being measured which represents the dielectric between the two electrodes. Air or vacuum has a relative dielectric constant of 1. Any other material has a higher dielectric constant. The capacitance of the capacitor therefore depends on how much material (=dielectric) lies between the sensor and the vessel wall. i.e.
how high the level is.
FEATURES
Different kinds of liquid level can be detected.
Robust mechanical structure and do not have moving parts is semi-permanent.
Stirrer attached to a container can be used.
highly corrosive liquid that can be used for.
Check the status of work in the field is possible.
