APPENDIX E - READING OTHER MANUFACTURERS’ SENSORS
Most vibrating wire gages available today have frequency characteristics that are within
the range of operation of the GK-401 Readout Box, and if they have the type of
electromagnetic coil that is used in the pluck and read system of the GK-401, it can be
used to read them.
Gage factors need to be known in order to convert readings to engineering units. The
readings can be taken in the period mode, Position A and, conversions to strain, pressure,
etc. can be made using the manufacturers' factors supplied with the gages.
The table below lists approximate operating frequency ranges for different wire lengths
for reference.
Wire Length
Frequency Range
1" 2500-5000
Hz
2" 1200-3000
Hz
3" 825-2000
Hz
4" 600-1600
Hz
6" 450-1000
Hz
10"
250-650 Hz
