Abstract
Improvements in devices for the monitoring of the operation of a totalizing circuit, of the type comprising a first integrating organ of an electric magnitude image of a physical quantity variable with the time to totalize, a threshold circuit connected to the output of the integrating organ and provides an impulse when the output voltage of the integrator reaches a threshold value, and a totalizing counter that counts the pulses, characterized in that said devices comprise a second integrating member which receives the electric quantity at the input, and which provides a voltage of output proportional to the integral in time of the magnitude, the second integrating member of a discharge member operating at each of the pulses being provided, and a comparator comparing the output voltage of the second integrating member with a voltage of reference and which controls a signaling, alarm and if necessary stop of the variations of the physical quantity when the output voltage reaches the reference voltage.
