Working Principle

Core Functional Features

1. Standard 10mm sensing head and M10×1 mounting thread, compatible with the reserved threaded holes of most medium and large steam turbines, compressors and blowers
2. ±2mm universal linear measuring range, covering most conventional vibration and axial displacement monitoring demands of industrial rotating machinery
3. Ultra-short probe body design without rear extension sleeve, specially suitable for bearing housings with extremely shallow internal installation depth
4. Non-contact measuring method, no mechanical contact friction between probe tip and rotating metal shaft, long service cycle
5. Measuring signal will not be interfered by lubricating oil, water vapor, dust and other mixed media inside the bearing box
6. The probe and supporting CON021 conditioner complete factory unified calibration, ensuring the overall linear measurement accuracy of the system
7. CON021 has built-in cable fault self-diagnosis, which can output fixed fault voltage signals to the upper monitoring equipment when the probe wire breaks or short-circuits
8. Standard linear negative voltage analog output signal, compatible with industrial DCS control systems, PLC, vibration protection instruments and all kinds of data acquisition modules

Application Scenarios

1. Medium and large steam turbine generator set shallow bearing box rotor radial vibration and axial thrust displacement monitoring
2. Heavy-duty centrifugal compressors, large industrial blowers and fans with shallow bearing housings rotor vibration protection measurement
3. Petrochemical plant large high-speed process pump and screw compressor shallow bearing rotor displacement online monitoring
4. Large hydraulic turbine generator unit rotating machinery fault early warning diagnosis system
5. Medium-sized gas turbine main rotor and auxiliary shaft vibration real-time monitoring

Installation Requirements

1. Probe Installation Specifications

   All probe installation operation specifications are consistent with the probe installation rules recorded under PR6424 010-110+CON021. Before locking the two anti-loose nuts, adjust the initial gap between the probe sensing head and the metal rotating shaft to the midpoint of the ±2mm linear measuring range.

2. CON021 Conditioner Installation Specifications

   All DIN rail installation, power supply wiring, analog signal wiring and shielding grounding specifications of the signal conditioner are completely consistent with the conditioner installation requirements under PR6424 010-110+CON021.
