Description

Technical Field

[0001] The utility model relates to the technical field of liquid level transmitters, and more specifically to a gas collecting hood liquid level transmitter. Background Art

[0002] The liquid level transmitter is an extension and development of the pressure transmitter technology. Based on the principle that the pressures generated by liquids of different specific gravities at different heights are in a linear relationship, it can accurately measure and transmit the volume, liquid height and weight of water, oil and paste.

[0003] The gas hood liquid level transmitter is a pressure sensor for measuring liquid level. It is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It uses an isolated diffused silicon sensitive element or a ceramic capacitor pressure sensitive sensor to convert the static pressure into an electrical signal, which is then converted into a standard electrical signal after temperature compensation and linear correction. It is generally suitable for liquid level measurement of various media in systems and industries such as petrochemicals, metallurgy, electric power, pharmaceuticals, water supply and drainage, and environmental protection.

[0004] During the use of the existing gas collecting hood liquid level transmitter, there is a lack of a structure for winding up the waterproof wires, which makes the cables chaotic. In addition, the waterproof wires are generally arranged for a long time, and part of them will be left outside, which is inconvenient to organize and greatly reduces the user's work efficiency. Secondly, the digital display screen of the liquid level transmitter will be contaminated with dust, affecting the viewing. For this reason, we propose a gas collecting hood liquid level transmitter to solve the above problems. Utility Model Content
