Throw-in type liquid level transmitter

Abstract

The invention relates to the field of liquid level transmitters, and discloses a throw-in type liquid level transmitter which comprises a liquid level transmitter body and a first connecting plate, the liquid level transmitter body comprises a junction box, a waterproof wire and a liquid level probe, a first mounting hole is formed in the first connecting plate, and one end of the junction box isfixedly mounted on the inner side wall of the first mounting hole; a first connecting electrode is arranged in the first mounting hole and fixedly mounted at one end of the junction box, a third mounting hole is formed in the bottom of the first connecting plate and communicated with the first mounting hole, a second connecting electrode is arranged in the third mounting hole, a first mounting groove is formed in the bottom of the first connecting electrode, and one end of the second connecting electrode is arranged in the first mounting groove in a penetrating mode. A winding drum is arrangedat the bottom of the first connecting plate, a waterproof wire is wound on the winding drum, a mounting hole II is formed in the winding drum, and one end of the waterproof wire penetrates through the mounting hole II and is fixedly mounted at the other end of the connecting electrode II. The throw-in type liquid level transmitter is convenient to use and diverse in function and has a good development prospect.

Description

technical field [0001] The invention relates to the field of liquid level transmitters, in particular to an input type liquid level transmitter. Background technique [0002] The submersible liquid level sensor is a pressure sensor for measuring liquid level. Based on the principle that the measured liquid static pressure is proportional to the height of the liquid, it uses isolated diffused silicon sensitive elements or ceramic capacitor pressure sensitive sensors to convert the static pressure into The electrical signal is converted into a standard electrical signal after temperature compensation and linearity correction. It is generally suitable for liquid level measurement of various media in petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage, environmental protection and other systems and industries. The transmitter is based on the principle that the measured liquid static pressure is proportional to the height of the liquid, and uses t...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a submersible liquid level transmitter to solve the problem that the existing submerged liquid level transmitter proposed in the above background technology requires users to frequently disassemble and install it during use. The connection device on the drop-in liquid level transmitter is relatively complicated to operate, and it takes a lot of time for the user to disassemble and install it, which greatly reduces the user's work efficiency and the models of the connection parts during installation are uniform. It is fixed, and the installation limit is relatively large. At the same time, the existing drop-in liquid level transmitter needs to manually wind up the waterproof wire when it is in use, which greatly reduces the user's work efficiency.
