Foreword
GB/T 21487 "shaft vibration measurement system" consists of the following components.
--- Part 1. Relative and absolute radial vibration detection;
--- Part 2. signal processing.
This section is GB/T Part of 121,487.
This part identical with ISO 10817-1.1998 "shaft vibration measuring systems - Part 1. Relative and absolute detecting radial vibration"
(In English).
This section is equivalent translation ISO 10817-1.1998.
For ease of use, this section made the following editorial changes.
--- With "this Part" instead of "this International Standard";
"." --- With a decimal point instead of a comma as the decimal point, "";
--- Deleted international standards foreword.
--- Of ISO 10817-1.1998 and other international standards referenced, there was equated adopted as our standard, instead of using our standard
Corresponding to international standards, is not tantamount to the adoption of a standard for the direct reference to international standards.
This section of the Appendices A and B are informative appendices.

GB/T 21487.1-2008/ISO 10817-1.1998
Shaft vibration measuring systems - Part 1.
Relative and absolute detection of radial vibration
1 Scope
GB/T 21487 in this part shows how to obtain reproducible measurements of rules, according to GB/T 11348 series of standards
Shaft vibration monitoring and evaluation. Therefore, it is mainly large machines with shaft vibration measuring about (example. turbogenerator, gas turbine
Units, industrial steam turbine, Turbine).
This section GB/T 21487 absolute and relative detection system is suitable for shaft radial vibration. It comprises detection means (i.e., sensors
), A suitable signal demodulator, connection methods and calibration procedures.
