Applications

Application 1 Axial Thrust Position Monitoring
For fluid-film bearing turbines and steam machines, the extended linear range of the 330706-005-046-10-02-05 allows accurate thrust position measurement over larger axial travel distances. With 3.94 V/mm sensitivity and −52°C to +177°C temperature tolerance, the probe ensures reliable feedback for thrust bearing protection and automated trip logic.

Application 2 Differential Expansion Analysis in Steam Turbines
Steam turbine casings experience thermal expansion gradients. The 11 mm 3300 XL system enables differential displacement tracking with stable 100 mV/mil output, improving thermal control models and optimizing startup sequences to reduce heat-induced stress and operational downtime.

Application 3 Rod Position and Rod Drop on Reciprocating Compressors
The mechanical wear of piston rods requires dynamic position profiling. This model supports non-contact rod drop analysis, allowing predictive maintenance scheduling that reduces unplanned outages and extends component lifecycle in process gas compressors and petrochemical assets.

Application 4 Tachometer and Zero-Speed Detection
The probe’s consistent voltage output supports high-resolution tachometry for rotating shafts. Zero-speed detection improves turbine turning gear operation, startup synchronization, and safety interlocks, especially in power generation facilities with automated sequencing systems.

Application 5 Keyphasor Phase Reference Sensing
The 330706-005-046-10-02-05 generates stable phase reference signals for vibration analysis systems. Precise phase angle data is essential for synchronous orbit analysis, shaft centerline plotting, and imbalance diagnostics on industrial turbines, compressors, and critical rotating equipment.

Specifications

Competitive Advantage

Advantage 1 Extended Linear Range for Complex Machinery
Compared to standard 8 mm probes, the 11 mm design increases linear measurement range, reducing signal dropout during large displacement events and improving data reliability for thrust and rod-drop applications.
