Claim:
1. A module for monitoring industrial processes for use in a system for monitoring industrial processes, which comprises sensor means for detecting one or more process quantities in at least one process station, acquisition means for acquiring measurement signals issued by said sensor means, processing means operating on signals generated by said acquisition means to obtain information on the quality of the process, and means for managing the production flow, which operate on the basis of said information on the quality of the process and are located in a workstation that is remote with respect to said process station, said monitoring module being configured for being set locally in said at least one process station for receiving measurement signals issued by said sensor means, wherein said measurement signals issued by said sensor means are analog signals in the 0-32 768 Hz band, wherein said monitoring module, set locally in said at least one process station, comprises: wherein said acquisition means comprises a voltage-to-frequency converter for converting said measurement signals into a pulse train at a variable frequency greater than or equal to 65 536 Hz, said remote workstation comprising wireless receiver means, at a radio frequency of 2.4 GHz, outputting said pulse train at a variable frequency greater than or equal to 65 536 Hz directly to a corresponding frequency-to-voltage converter that converts said pulse train received by the wireless receiver means, and an acquisition card, operating at a maximum frequency of 65 536 Hz, for acquiring the signal converted by said converter and supplying it to the processing means.
