UNIVERSAL MODULE OF FREQUENCY INTEGRATION DEVELOPING TRANSDUCER FOR SENSORS OF PHYSICAL VALUE SENSORS Russian patent published in 2017 - IPC H02M5/27 G01R23/09 G01D7/00 

FIELD: measuring equipment.

SUBSTANCE: proposed universal module of the integration developing transducer for physical quantity sensors contains a housing, electrical contact pins mounted in the housing, operational amplifiers, resistors and capacitors. The first electrical contact terminal is connected through the first resistor to the inverting input of the first operational amplifier, the second input of which is connected to the second electrical contact terminal. The third electrical contact terminal is connected through the second resistor with an inverting input of the first operational amplifier. The fourth electrical contact terminal is connected to the non-inverting input of the second operational amplifier. The fifth electrical contact terminal is connected to the inverting input of the third operational amplifier. The sixth electrical contact terminal is connected to the non-inverting input of the third operational amplifier. The seventh electrical terminal is connected to the electrical terminals of the electrical supply minus of the first, the second and the third operational amplifiers. The eighth electrical contact terminal is connected to the output of the first operational amplifier. The ninth electrical contact terminal is connected to the inverting input of the first operational amplifier. The tenth electrical contact terminal is connected to the output of the second operational amplifier. The eleventh electrical contact terminal is connected to the output of the third operational amplifier, and the twelfth electrical contact terminal is connected to the electrical terminals of the electric power supply of the first, the second and the third operational amplifiers. The inverting input of the first operational amplifier is connected through the first capacitor to the output of the first operational amplifier, the inverting input of the second operational amplifier and the eighth electrical contact terminal, and is connected directly to the ninth electrical contact terminal, which, via the second capacitor, is connected to the output of the second operational amplifier and the tenth electrical terminal connected through the third resistor to the inverting input of the third operational amplifier, the output of which through the fourth resistor is connected to the inverting input of the third operational amplifier.

EFFECT: increasing the functionality of the device, increasing the versatility and simplifying the design.
