Description：

The design of the PROXPAC XL Proximity Transducer Assemblyis similar to our 31000/32000 Proximity Probe HousingAssemblies. The assembly offers the same advantages andfeatures as the 31000 and 32000 housings for accessing andexternally adjusting proximity probes. However, the housingcover of the PROXPAC XL Assembly also contains its own 3300XL Proximitor sensor. This design makes the PROXPAC XLAssembly a completely self-contained proximity probesystem, and eliminates the need for an extension cablebetween the probe and its associated Proximitor sensor. Italso eliminates the need for a separate Proximitor housing, asthe field wiring connects directly between the monitors andPROXPAC XL Assemblies.

Product Applications

Electric power industry: Used for shaft monitoring of steam turbines, gas turbines and hydro turbines.

Petroleum and natural gas: Monitoring of centrifugal and reciprocating compressors, large pumps, and turbine-driven equipment.

Chemical and petrochemical: Applicable for real-time displacement and vibration monitoring of key rotating equipment in fertilizer plants and refineries.

Heavy industry (mining and metallurgy): Measuring the operating status of shafts in large fans, electric motors and gearboxes.

Specific monitoring functions

Radial vibration measurement: Real-time monitoring of the radial wobble of the rotating shaft relative to the bearing to prevent mechanical failures caused by abnormal vibration.

Axial position (thrust) monitoring: Measuring the axial displacement of the rotating shaft to prevent the rotor from colliding with stationary components.

Speed and keyphasor measurement: By measuring the keyways or protrusions on the shaft, providing precise speed data and phase reference to assist in fault diagnosis and dynamic balance analysis.

Fluid statics/dynamics analysis: Monitoring the oil film state and rotor dynamic characteristic indicators on fluid film bearing machines.
