1 Scope

The Verification System applies (-2.5 ~ 2.5) kPa pressure range of pressure measuring instruments of value transfer. this Verification System provides name within this pressure range baseline measurement instruments pressure measuring instruments, measuring range, with Transit, transfer method, reproduce the magnitude of uncertainty (or value transfer should be to achieve the best measurement capability) to Composition and working standards of measurement and measuring instruments of pressure measuring instruments name, range, use, transfer Party Method and the maximum permissible error; specifies the amount of pressure within the pressure range is transmitted to the State by reference standards of measurement Delivery methods and measuring instruments work pipeline.

2 baseline measurement

2.1 baseline measurement name. 2500Pa pressure reference devices. 2.2 Scope of the baseline measurement uncertainty and composition Pressure Range. (- 2.5 ~ 2.5) kPa. Uncertainty. 0.13Pa (k = 2). 2500Pa pressure reference device uses the principle of compensation, the use of displacement of the movable container to compensate for pressure changes Fixed container caused by changes in the level of zero. It mainly consists of a container system (including fixed container and movable container) Heated water tank, zero positioning system, the displacement measurement system. Its working medium is deionized water. 2.3 magnitude baseline measurement traceability and guarantee 2500Pa pressure reference device by measuring the density of the working medium, and the gravity field measurements Highly accurate measurement so as to reproduce the pressure of traceability to length, mass, time, three basic amount. By participating in international quality and related amounts Advisory Committee on Metrology (CCM) or the Asia-Pacific Metrology Key (APMP) organization than to ensure that the magnitude of the pressure of international pressure magnitude unity. 2.4 reference measurement value transfer 2500Pa pressure reference device direct comparison method to deliver first-class standard to compensate the decline of pressure meter, the maximum allowed Error of ± 0.3Pa to ± 0.5Pa liquid pressure gauge, the maximum permissible error of ± 0.25Pa live micro-pressure gas Plug gauge.

3 measurement standard

Micro pressure measurement standard equipment including first-class standard to compensate the decline of pressure meter and second standard to compensate the decline of pressure gauge, pressure liquid formula Gauge, micro-pressure gas piston gauge and digital pressure gauge and so on. First decline of 3.1 standard compensation pressure gauge measuring range (-2.5 ~ 2.5) kPa, when the pressure value in (-1.5 To 1.5) kPa within the range, the maximum permissible error of ± 0.4Pa; pressure values at (-2.5 ~ -1.5) And within kPa (1.5 ~ 2.5) kPa range (excluding -1.5kPa and 1.5kPa), the maximum permissible error ± 0.5Pa.
