Hardware Specifications

Mechanical Monitoring and TSI Integration

System accuracy is contingent upon rigorous eddy-current probe scaling protocols. The 330881 assembly requires calibration against the target shaft material to ensure linear output. Field technicians must validate the system gap voltage, targeting a nominal -10 VDC at the linear range midpoint to optimize signal range. Cross-talk suppression is maintained by ensuring adequate spatial separation of the probe tip from other electromagnetic sources and metallic structures, thereby ensuring reliable rotor dynamics data extraction during transient and steady-state machine operation.

Field Installation Guidelines

• Structural Mounting: Ensure the transducer is mounted to a rigid machine surface; minimize mechanical resonance between the housing and the frame.

• Threaded Interface: Use caution when tightening the probe threads; adhere to specified torque limits to avoid internal housing deformation.

• Grounding: Bond the transducer housing to the machine earth ground to facilitate electrostatic charge dissipation.

• Environmental Sealing: Confirm that all conduit entries are sealed with the provided plugs to maintain the IP66 ingress protection rating.

Frequently Asked Questions

• Can the 8 mm probe tip be removed? No, the probe assembly is factory-integrated and sealed within the PROXPAC XL housing.

• Is the housing material conductive? Yes, it is designed for effective electrostatic charge dissipation.

• What is the linear range of this transducer? The system is designed for a 2.0 mm linear operating range typical of 3300 XL 8 mm probes.

• How do I identify a faulty transducer? A "Not OK" status on the monitor rack, typically indicated by a voltage at the power supply limit, indicates a probe or cable failure.

• Can this be used in explosive environments? Verification of the agency approval code is required; ensure the site classification matches the transducer rating.

• Is the housing compatible with existing conduit systems? Yes, it is designed to interface with standard industrial conduit and cable glands.

• What effect does thermal expansion have? Probe position must account for machine casing expansion to keep the probe within its linear gap range.

• Are there torque limits for the mounting hardware? Follow the provided installation manual for torque specifications to ensure a secure, distortion-free mount.
