Abstract

The invention provides an on-line precise densimeter capable of carrying out wireless data transmission. The on-line precise densimeter comprises a machine shell and a hardware circuit which is positioned in the machine shell, wherein the hardware circuit comprises a strain sensor and a wireless data transmission module which is connected with the strain sensor, a strain girder of the strain sensor is provided with a lifting hook extending out of the machine shell, and the tensile force of a suspended object on the lifting hook is measured by the strain sensor, and is sent out through a wireless data transmission module. According to the on-line precise densimeter capable of carrying out wireless data transmission disclosed by the invention, a measuring method and precision are greatly improved, and the densimeter can be applied in many technical fields. Because the measuring principle is clear and the precision is greatly improved, the densimeter can be used as a measurement standard under a certain condition; and because wireless data transmission is available, monitoring automation can be greatly improved, the cost of production is greatly reduced, and the work efficiency is greatly improved.

Description

technical field [0001] The invention relates to a density meter, in particular to a wireless digital transmission online precision density meter. Background technique [0002] Currently commonly used density meters include float density meters, static pressure density meters and radioisotope density meters. [0003] The working principle of the float density meter is as follows: the buoyancy of the object in the fluid is related to the density of the fluid, the greater the density of the fluid, the greater the buoyancy. At this time, the glass scale of this kind of density meter roughly estimates the density of the liquid to be measured, and the error is extremely large, so it is not suitable for use in occasions requiring high precision. [0004] The working principle of the static pressure density meter is as follows: the static pressure of a liquid column at a certain height is proportional to the density of the liquid, so the density of the liquid can be measured accord...
