Product Details
The intelligent universal electric contact liquid level monitor is an electric contact liquid level measurement, display and control instrument composed of a measuring cylinder, an ultra-pure ceramic electrode and a display instrument. It uses red and green two-color light-emitting tubes to simulate steam (red) and water (green) in the display, clearly indicating the position of the liquid level in the container, and has functions such as over-limit alarm and output.Side Mounted 4-20ma Boiler Water Electrode Level Gaguge For Water Tank

Working Principle
Since the electrical conductivity of water and steam is very different, the function of the measuring cylinder is to obtain credit for the change of the water level through the change of the electrical contact resistance. In the liquid state, due to the small resistivity of the medium, when a voltage is applied between the electrical contacts, the current flowing is large; on the contrary, the current flowing through the electrical contacts that are not immersed in the liquid surface is small. The current flowing in these two states is very correlated, and can be used as a signal lock to the secondary instrument. After amplification, it can display and control the output, thereby realizing long-distance monitoring.
Product Advantages
1. The display part of the instrument adopts two modes of analog display and digital display at the same time.
2. The number of display points can be arbitrarily set within the range of 6 to 19 points according to user needs.
3 The scale value of each ruler can be set arbitrarily through panel operation,
4. It has the function of sound and light alarm for liquid level exceeding the limit and the selection of various alarm modes. The position of the alarm point can be arbitrarily set within the scale range.
5. With automatic judgment and tracking function of water resistance,
6. Has a strong fault tolerance
7. Strong anti-interference ability to prevent false alarms in the case of instantaneous strong interference.
