4.4 Function Features

1. 32mm oversized coil sensing head, wider ±4mm linear measuring range, suitable for large shafts with high displacement swing amplitude
2. Strong anti-interference magnetic field design, stable measurement data for large-area metal rotating target surfaces
3. Compatible with CON021 series pre-converters, supporting standard negative DC power supply and linear analog voltage output
4. Stainless steel high-temperature probe sleeve, PTFE high-temperature resistant signal cable, industrial anti-vibration structure

4.5 Working Principle, Material Composition, Application Scenarios, Installation & Precautions

1. Eddy current induction working principle identical to PR6424/PR6425 series probes
2. Main application: Ultra-large steam turbine generator rotors, large mine centrifugal fans, heavy metallurgical rolling mill main drive shaft radial vibration and axial displacement monitoring
3. Special installation requirement: Must ensure the measured metal shaft diameter is no less than 200mm; small-diameter shafts will cause severe measurement signal distortion
