Adjacent two brachium pontis of bridge, bridge diagonal is constituted by the first inductance coil L1, the second inductance coil L2
Outfan is by the first diode D1 to the 4th diode D4 and additional first resistance R1 to the 4th resistance R4 group
Becoming phase-sensitive rectifier, electric current is indicated by ammeter PA.First potentiometer RP1 is zero potentiometer, the second electricity
Position device RP2 is used for regulating ammeter PA ull-scale value.Bridge power supply is powered by transformator T.5th resistance
R5, the 3rd electric capacity C3 and the 4th electric capacity C4 strobe.
When the armature in inductance sensor is in an intermediate position, bridge balance, no current stream in ammeter PA
Cross.When the thickness of measured piece changes, the most in two kinds of situation: if the first inductance coil L1 > second
