The simple structure digital capacitance level transmitter is based on the principle of capacitance sensing, which causes the capacitance to change when the height of the electrode is changed by the measured medium.
It converts changes in the height of various objects and liquid levels into standard current signals and goes far to the operating control room for centralized display, alarm, or automatic control of secondary instruments or computer devices. Its good structure and installation method can be applied to high temperature, high pressure, strong corrosion, easy crystallization, anti-clogging, anti-freezing, and solid powdery, granular materials.
It can measure the liquid level of the strongly corrosive medium, measure the level of the high-temperature medium, measure the level of the sealing container, and have nothing to do with the viscosity, density and working pressure of the medium.
Features
l Simple structure with no movable or elastic components, resulting in extremely high reliability and minimal maintenance
l Various signal outputs for easy configuration of different systems
l Suitable for liquid level measurement of high temperature and high-pressure containers, and the measured values are not affected by the temperature, density and container shape and pressure of the liquid being measured.
l Ideal for the measurement of highly corrosive liquids such as acids and alkalies
l Perfect Over-current, over-voltage, power supply polarity protection
