Patent ID: 11914002
Assignee: CROUZET AUTOMATISMES
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 1:
2. The installation of claim 1, wherein:
the microprocessor is also programmed to indicate the interrupted state of the second power supply cable if the value of the digital signal corresponds to a second predetermined fault value, the second predetermined fault value being different from the first predetermined fault value and being outside any predetermined measurement range; and
the monitoring module further comprises a third transistor comprising a first and a second power electrode and a control electrode, this third transistor being capable of switching, as a function of the control signal received on the control electrode thereof, between:
an open state, in which the power electrodes thereof are electrically isolated from each other; and
a closed state, in which the power electrodes thereof are electrically connected together;

the first and the second power electrodes of the third transistor being electrically connected to the first power supply cable and to the measurement cable, respectively, so that, when the third transistor is in the closed state thereof, the second predetermined fault value is generated on the measurement cable,
the control electrode of the third transistor being connected to the second power supply cable, so that the loss of current on the second power supply cable, caused by the interruption thereof, automatically triggers the switching of the third transistor to the closed state thereof and so that, alternatively, the absence of interruption of the second power supply cable keeps the third transistor in the open state thereof.
