Abstract

The invention discloses a split type low-loss guided wave radar liquid level meter. The device comprises a radar probe assembly, a radar detection assembly and a radio frequency cable; the radar probeassembly and the radar detection assembly are detachably connected through the radio frequency cable; the radar probe assembly comprises an instrument cover, a guided wave radar module, an instrumentshell, a connection structure and a first radio frequency joint; the guided wave radar module is arranged in the instrument shell; and one end of the guided wave radar module, opposite to the other end of the guided wave radar module, is connected with one end of the first radio frequency connector through the connecting structure. According to the split type low-loss guided wave radar liquid level meter of the invention, the radar probe assembly and the radar detection assembly are well designed, so that the split installation of the guided wave radar liquid level meter is realized; the low-loss connection of the two parts is realized through the radio frequency cable, and therefore, the problem that guided-wave radar liquid level meters on the existing market cannot be installed in a split manner is solved; and the guided-wave radar can be better applied to an industrial field with severe environment and severe interference without adopting additional reinforcing anti-interference measures.

Description

technical field [0001] The invention relates to the technical field of radar liquid level gauges, in particular to a split-type low-loss guided wave radar liquid level gauge. Background technique [0002] In the implementation process of industrial process control and factory automation, it is very important to be able to measure the height of material level stably and reliably. Guided wave radar level gauge is very suitable for actual needs because of its fast and stable measurement, high accuracy, easy setting and low cost. Guided wave radar level gauge is an electromagnetic wave ranging system based on the principle of time travel. When the electromagnetic wave touches the surface of the measured material, the electromagnetic wave will be reflected back due to a sudden change in the dielectric constant. The time interval between the emission and reception of electromagnetic waves is proportional to the distance from the radar probe to the measured medium, so the distance...
