DEVICE FOR CONTROLLING ROTATION FREQUENCY Russian patent published in 2005 - IPC

FIELD: control and measurement technologies.

SUBSTANCE: device has rotation frequency sensor, pulse generator, measuring block, data analysis block and constant current voltage source, and also five resistors and capacitor. First output of rotation frequency sensor through first resistor is connected to positive bus of symmetric voltage source and through second resistor to first input of pulse generator with differential input, second input of which through third resistor is connected to second output of rotation frequency sensor and to common power bus, through fourth resistor - to negative bus of symmetric voltage source, through fifth resistor - to input of measurement block and output of pulse generator with differential input, first and second inputs of which through capacitor are connected to each other, output of measurement block is connected through data analysis block to device output, pulse generator is mad in form of pulse generator with differential input, and constant current voltage source is made in form of symmetric voltages source.

EFFECT: higher reliability.
