| Abstract: | On the basis of the prototype of suspend gap sensor, these were systematically introduced including the principles of measuring suspend gap by electric eddy current effect and construction of the sensor. Resolved some key problems such as resonance and signal processing by selecting special resonant circuit and taking other measurements. Test results show that the prototype has the basic capability of measuring the gap, whose linearity is good in the general working condition. |
