G08C TRANSMISSION SYSTEMS FOR MEASURED VALUES, CONTROL OR SIMILAR SIGNALS (fluid pressure transmitting systems F15B; mechanical means for transferring the output of a sensing member into a different variable G01D5/00; mechanical control systems G05G)
Description
G08C covers transmission systems and signal transmission methods for conveying measured values, control signals, and similar information between remote locations or devices. This subclass encompasses both wired and wireless transmission technologies, including signal encoding/modulation techniques, transmission protocols, and infrastructure for telemetry, remote control, and data communication in measurement and control applications. Typical technologies include analog signal transmission, frequency modulation systems, pulse code modulation, and wireless transmission methods for industrial, utility, and automation systems. This classification excludes general data transmission and telecommunications systems covered by H03 and H04, focusing instead on applications where signal transmission is integral to measurement acquisition or remote control functionality.
