Title: Measurement of resistance variations - employs Wheatstone bridge with resistance switched in parallel with one arm during nulling
IPC: G01D5/16
Filed: 1975-03-13
Abstract: Relative variations in the ohmic value of a resistance to represent changes of a physical parameter are measured on a Wheatstone bridge. The bridge is powered from a square wave generator and balance is obtained by conexion of a controlled variable resistance in parallel with one arm. A Wheatstone bridge (10) contains a resistance (11) whose variation is to be measured. The bridge is powered from a square wave generator (21) and the bridge output (BD) voltage is amplified (15) and detected (16) by a synchronous detector followed by a filter integrator (17) to obtain the average output value. This output determines pulse duration of a monostable (24) triggered by leading edges from the pulse generator (21). This causes an FET (25) to connect a resistor (18) in parallel with one bridge arm (BC). Balance occurs when the integrator input is nulled.
