The difference between 26G radar level meter and 80G radar level meter

Time: 2024-09-09
Equipment Configuration:80G radar level meter

When it comes to radar level meters, I believe that friends who are engaged in the level industry must be familiar with it.

Project Overview

When it comes to radar level meters, I believe that friends who are engaged in the level industry must be familiar with it. In fact, its scientific name is "microwave level meter". Its working principle is to emit microwave pulses from an antenna. This pulse travels in space at the speed of light. spread. When it hits the surface of the medium, part of its energy is reflected back and received by the same antenna. The time interval between transmitting pulses and receiving pulses is proportional to the distance from the antenna to the surface of the measured medium, thus calculating the distance from the antenna to the measured surface.

So we often see radar level meters starting with 26G and 80G in product manuals. What do 26G and 80G mean respectively? Let the editor answer the questions for you:

First of all, let’s introduce microwaves. Microwaves refer to electromagnetic waves with frequencies between 300MHz and 300GHz. The wavelengths are between 1 mm and 1 meter. They are decimeter waves ( The collective name for 300MHz~3GHz), centimeter wave (3~30GHz) and millimeter wave (30~300GHz).

The wavelength used by the 26G radar level meter is 11mm, which is a detection microwave radar in the centimeter wave band. The wavelength used by the 80G radar level meter is 4mm, which is a detection radar that works in the millimeter wave band. Therefore, the 26G radar The difference between a level meter and an 80G radar level meter is that the wavelengths emitted by microwaves are different. Therefore, when selecting a radar level meter, you must consider the specific working conditions and actual parameters to select a product with the appropriate wavelength.
