Barometric altimeter calibration procedures
1 Scope
This regulation is applicable to mechanical barometric altimeters with a bellows as a sensitive element with a measuring range below 11000m.
(hereinafter referred to as the altimeter) initial calibration, subsequent calibration and in-use inspection.
This procedure does not apply to the calibration and in-service inspection of airborne air pressure altimeters for aviation.
2 cited documents
This regulation cites the following documents.
JJG 272-2007 Calibration Regulations for Empty Box Barometers and Empty Box Barometers
For dated references, only the dated version applies to this regulation; for undated references, only the dated version applies.
The latest version (including all modification orders) shall apply to this regulation.
3 Terminology and units of measurement
3.1 Terminology
3.1.1 geopotentialheight geopotentialheight
In the earth's gravity field, the height represented by the potential energy of unit mass of air relative to sea level.
3.2 Unit of measurement
The unit of measurement is meters (m) or kilometers (km).
4 Overview
The altimeter is used to measure the height difference between two locations, using the principle of barometric altimetry. Altimeter made of vacuum membrane
It consists of a box, air pressure dial, height dial, transmission mechanism, etc. When the air pressure changes, the center of the vacuum membrane box produces
The generated displacement is amplified by the transmission mechanism, driving the pointer to move along the scale surface, indicating the height value corresponding to the air pressure.
The relationship between atmospheric pressure and geopotential height can be expressed by equation (1).
p=p0 1
T0
(H-H0)

In the formula.
p ---Atmospheric pressure at H, hPa;
p0 ---standard atmospheric pressure at mean sea level, taken as 1013.25hPa;
L ---The vertical gradient of atmospheric temperature in the troposphere, taken as -0.0065K/m;
T0 ---The thermodynamic temperature of the atmosphere at mean sea level, taken as 288.15K;
H ---The geopotential height somewhere above (or below) mean sea level, gpm;
H0 ---Geopotential height at mean sea level, 0gpm;
g0 --- standard gravity acceleration, take 9.80665m/s2;
R --- Dry air specific gas constant, taken as 287.05287J/(K·kg).
