3 Terms and Definitions
GB/T 7665, GB/T 50279 and established the following terms and definitions apply GB/T 3410 of this part.
3.1
Use natural frequency vibrating wire sensing a change in the amount of deformation of the vibrating wire sensors.
3.2
In the measuring range, vibrating wire joint meter minimum change in value can be measured sensed, expressed as a percentage of full scale output.
3.3
Squared algebraic difference vibrating wire joint meter operating characteristics determined by the maximum output frequency of the square and the minimum output frequency.
Note. The modulus frequency (output frequency divided by the square of 1000) for the output of the vibrating wire joint meter, the full-scale output can be characterized by its maximum output frequency mode
Algebraic difference between the number and minimum output frequency modulus.
3.4
The maximum and minimum output frequency output frequency algebraic vibrating wire joint meter operating characteristics determined by the difference.
