Abstract： |
The system includes control rod assembly, chain wheel-link belt, current vortex sensor, precision lead screw-nut assembly and body to be measured. The said precision lead screw-nut assembly includes precision lead screw, nut and support. Precision lead screw is connected to chain wheel, and the body to be measured is fixed on the nut. The current vortex sensor includes probe of sensor, signal transmission cable and preamplifier. Sealed penetration piece welded to pressure borderline of a loop is setup in middle of the signal transmission cable. Probe of sensor fixed on the said support is corresponding to the body to be measured. The advantages are high measurement accuracy, fast speed, stable operation and easy of maintenance. |
