Description

technical field

[0001] The invention relates to the technical field of instruments and meters, in particular to a T-shaped platform three-point level with liquid metal as a working medium. Background technique

[0002] The traditional spirit level is a straightedge bubble type with a small measurement range, and can only distinguish a small range of places at the same height: some people also invented a four-point level. When using a four-point level, three points are often overhead and one point is not recognized. If it is found, it will cause a big mistake. Contents of the invention

[0003] In order to solve the deficiencies in the prior art, the present invention is achieved in this way: the T-shaped platform three-point level gauge with liquid metal as the working medium uses the liquid metal as the working medium, and the T-shaped platform 1 and the three-point level that constitutes an equilateral triangle or a right-angled triangle are formed on the platform. A re...

Examples

specific Embodiment approach

[0012] T-shaped platform three-point level with liquid metal as the working medium: liquid metal is used as the working medium, consisting of T-shaped platform 1, three reference points forming an equilateral triangle or a right triangle on the platform 2, three metals with long grooves and The vertical tube 3 of the ruler, three transparent tubes 4 connected by a three-way liquid metal; the three-way 5 is composed of; use liquid metal as a working medium, and what is used here is a ternary eutectic liquid metal, which contains 62% gallium , 25% indium, 13% tin, density 5.91g / cm 3 , melting point is 5℃, conductivity is 6.78××10 6 / (s / m), the vapor pressure is close to zero, and the liquid metal vapor pressure is extremely low, making the measurement accurate, safe and non-toxic; the three metal vertical tubes 3 with long slots and scales are exactly the same as the T-shaped platform 1 Vertically fixed on the three reference points 2 forming an equilateral triangle or a right ...
