Working Principle
The core eddy current signal conversion working principle of PR6423 000-101-CN miniature probe is completely identical to PR6424 series probes. The China localized -CN version only optimizes factory calibration parameters to adapt to domestic common steel shaft materials, without changing high-frequency electromagnetic field excitation, eddy current induction, coil impedance variation detection and linear voltage demodulation logic of CON021 conditioner. This medium-length miniature probe balances installation depth and measuring range, suitable for most domestic small and medium turbomachinery vibration monitoring projects. The matched CON021 conditioner still retains complete cable open/short-circuit fault self-diagnosis function.
Core Functional Features
