摘要: The sensor unit (1) has a detection module (12) i.e. analog-digital converter, for detecting measured quantity current, and modulation (16) modulating frequency pulse width. A potential-free transmission (17) an optical and/or magnetic path, opto-coupler fiber optic cable. exhibits coding of 8 bits measuring signals in width frequency, respectively. detects voltage proportional to current detected at shunt (21) includes programmable amplifier achieve high resolution. An independent claim is also included method transmitting signal data.
