Specific weight measurer

Abstract

A specific gravity measuring device, which can reliably and quickly obtain the specific gravity of various solid substances through one measurement operation very simply. The specific gravity measuring device includes: a liquid tank; a first measuring part supporting the liquid tank; a measured object receiver, which is set in the liquid tank and immersed in the liquid; a second measuring part , the second part of the measuring part supports the measured object receiver in a non-contact manner relative to the liquid tank; an arithmetic operation unit is used to calculate the specific gravity value according to the measured values ​​of the first and second measuring parts; and A display device is used to display the specific gravity value obtained by the arithmetic operation unit. The first measuring part measures the increase in weight as the measured object is immersed in the liquid as a buoyant force, and the second measuring part measures the weight of the measured object in water. The arithmetic operation unit finds specific gravity from the measured buoyancy and weight in water to display them on the display device.

Description

(1) Technical field [0001] The present invention relates to a specific gravity measuring device which can be used for measuring various substances. In addition to solid substances such as precious metal alloys, synthetic resins, ceramics, rubber, fibers, etc., its measurement range also includes powdery substances, granular substances and liquid substances. (2) Background technology [0002] In general, in order to know the specific gravity of a solid substance with an unknown volume, first use the Archimedes principle to find the volume of the solid substance, that is, use the buoyancy of the substance in the liquid to be equal to the weight of the liquid displaced by the solid substance principle. The next step is to measure the weight of the solid matter in air and to measure its weight in the liquid while completely submerged in a liquid of known specific gravity (usually water has a specific gravity of 1) to derive the buoyancy as the difference between the weight in a...

AI Technical Summary

Problems solved by technology

But all traditional specific gravity measuring devices need to carry out two-level measurement: first measure the weight of the measured object in the air, and then immerse the measured object in water (in the liquid) to measure its weight or buoyancy, so it takes a lot of effort to compare Multiple working hours and long measurement times

Especially, when it is necessary to measure the specific gravity of different objects in turn, the efficiency of the traditional measuring device is too low
