Reduced Measuring Range for Enhanced Resolution
The PR6422/002-101 features a 1 mm linear measuring range. This narrower span provides superior resolution for axial displacement monitoring. Consequently, you detect minute thrust position changes before mechanical contact occurs. The M10 × 1 thread accommodates space-constrained bearing housing installations.
Specialized Design for Thrust Monitoring
EPRO engineered this sensor specifically for end-play and axial position applications. The reduced tip diameter permits installation through existing casing drillings. You mount the PR6422/002-101 directly opposite the thrust collar face. Two integrated lock nuts maintain precise air gap settings during operation.
Environmental Durability Without Compromise
This sensor withstands continuous exposure to turbine oil mist and water spray. The IP68 rating guarantees complete protection against ingress. Fluorocarbon cable insulation resists hydraulic fluids and aromatic hydrocarbons. Therefore, the PR6422/002-101 performs reliably in the harshest turbine environments.
Passive Sensing for Uninterrupted Service
No internal electronics exist within the PR6422/002-101 probe body. The passive eddy current coil requires no local power or energy storage. This design eliminates drift over time and temperature. You achieve consistent measurement accuracy for decades of continuous service.
System Integration and Signal Compatibility
The PR6422/002-101 connects directly to EPRO CON011 series converters. The driver unit supplies RF excitation and demodulates the impedance variation. Your control system receives a standardized voltage proportional to shaft displacement. Many users pair this sensor with RMS series protective relays for complete machinery protection schemes.
