Measurement and signal path of circular geometry elements, in particular for active measurement of bearing rings during the grinding process

摘要

The gauge-signal track has a combined active variable inductance measuring head, an LVDT converter with a conditioning system, favourably AD698 where the input signal is directly connected to the input (AIN) and (AIN),freely programmable microprocessor controller and operating panel. It is characterized by the variable induction (Lv) of the head (1) coupled in series with the constant resistance (R) being fed from the output (EXC1, EXC2) of the generator (2) and connected parallel to the input (BIN, BIN) of the generator (2) and the input (C and D) of the phase-shifter system (3) as a microprocessor controller, the signal the variable induction input (Lv) of the head (1) is connected directly to the generator input (AIN and AIN).
