DEVICE FOR SIGNAL MONITORING Russian patent published in 2014 - IPC G01H11/06 H03H11/12 

FIELD: measurement equipment.

SUBSTANCE: into a device for signal monitoring there are additionally introduced buses of initial voltage and alarm, a threshold element, an analogue key with a control inlet, the third resistor, a diode, the cathode of which is connected with a power supply bus and an inlet of an integrating RC-circuit, the outlet of which is connected to the anode of the diode and the inlet of the threshold element, the outlet of which is connected to the first outlet of the second resistive divider and the control inlet of the analogue key, the inlet of which is connected with the bus of the initial voltage, and the outlet - with the first outlet of the first capacitor, the second outlet of which via the third resistor is connected with the common bus, the bus of the medium value is connected to the first inlet of the second operational amplifier, the outlet of which is connected with the bus of alarm, the second outlet of the second resistive divider is connected either with the power supply bus, or with the common bus.

EFFECT: expansion of functional capabilities, reduced time of availability and provision of noise immunity.
