Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics Integration

The internal 3300 XL 8 mm probe operates through high-frequency eddy-current probe scaling, converting physical displacement into proportional electrical voltage. Because the probe is housed within the 32000-28-05-05-060-00-02 protective casing, field calibration requires careful mechanical adjustment.

During commissioning, gap voltage validation is performed by sliding the probe within the sleeve until a nominal target voltage of -10 VDC is met. This ensures the probe is centered within its linear range, enabling precise tracking of high-frequency rotor dynamics on turbomachinery without signal clipping.

Field Installation Guidelines

• O-Ring Inspection and Alignment

  Verify that the internal Viton O-ring and the Neoprene sleeve-to-housing O-ring are intact. These elastomer barriers prevent oil mist migration and maintain NEMA 4X / IP66 ingress ratings.

• Thread Engagement and Torquing

  Ensure a minimum of five full threads of engagement when mounting the 3/4-14 NPT body into the machine case. Apply industrial-grade thread sealant to prevent mechanical loosening caused by continuous machinery vibration.

• Connector Coupling and Routing

  Connect the coaxial leads using ClickLoc connectors on the 0.5-meter cable, tightening until they audibly "click". Coil the coaxial excess neatly inside the housing dome, avoiding tight bends to prevent cable pinching when sealing the cover.

Frequently Asked Questions

• How is the target gap voltage validated when using this housing assembly?

  A multimeter is connected to the Proximitor loop while the probe depth is mechanically adjusted within the housing sleeve to achieve the nominal -10 VDC calibration baseline.

• Are 3300 XL 8 mm probes hot-swappable while the machine is running?

  Yes, the housing design allows the probe and sleeve to be safely withdrawn and replaced from the exterior of the machine casing without shutting down the process.

• Does this housing assembly resist internal machine casing pressure?

  The Viton O-rings seal against differential pressure, but the PPS plastic housing is designed to shield against environmental hazards and is not rated for high-pressure containment.

• What is the purpose of the 0.5 inch standoff adapter option on this model?

  The standoff adapter extends the physical position of the housing shell away from the machine wall, allowing precise alignment for the 6.0 in penetration option.

• Can a 7200 Series extension cable be paired with the integrated probe?

  No, 3300 XL probes are electrically incompatible with 7200 Series extension cables and Proximitors due to distinct electrical parameters.

• What materials are compatible with the default eddy-current calibration of this sensor?

  The scaling of the probe is calibrated for AISI 4140 steel; using other target shaft alloys will skew the linear measurement and require calibration.

• What occurs if the Neoprene sleeve-to-housing O-ring is damaged?

  Moisture and particulates will breach the internal chamber, causing degradation of the coaxial cable connection and potential signal drift.

• Why does this specific model option (00) include plugs but no conduit fittings?

  Option 00 is configured for installations where the customer provides their own liquid-tight conduit couplers or routes armored cable through existing cable seals.
