Hardware Specifications

Mechanical TSI Integration

The housing assembly facilitates precise eddy-current probe scaling by providing a rigid mechanical reference point. Correct installation ensures the transducer maintains the required gap distance from the rotor surface, allowing the Proximitor to output a linear signal within the nominal -10 VDC range. Mechanical stability is a requirement for accurate rotor dynamics interpretation; the assembly is constructed to mitigate resonance-induced noise and minimize cross-talk interference between adjacent proximity channels in high-density mounting arrays.

Ordering info

• One (1) 31000-26-05-00-100-03-02 Proximity Probe Housing Assembly.

• Standard lock nut and jam nut hardware.

• O-ring seal kit for pressure-tight installation.

• Note: Verify machine port thread pitch compatibility prior to final torque application.

Installation Protocols

• Port Preparation: Clean the machine port of all residual thread sealant and metal particulates to ensure a pressure-tight seal.

• Alignment: Ensure the housing remains perpendicular to the shaft centerline; verify that the probe tip can reach the target area without mechanical binding.

• Depth Setting: Establish the mechanical gap using a depth micrometer; tighten the lock nuts only after the required gap voltage is confirmed at the monitor input.

• Grounding: Secure the stainless steel housing to the machine chassis to maintain a consistent ground path for electromagnetic shielding.

• Conduit Management: Secure the coaxial cable within the conduit fitting; avoid sharp bend radii that can degrade the internal cable shield.

Frequently Asked Questions

• Can this housing be used for radial vibration monitoring?

  Yes, it is designed for mounting proximity probes used in radial vibration, shaft axial position, and speed monitoring applications.

• What is the impact of housing resonance on signal data?

  Mechanical resonance in the housing assembly can introduce false vibration data or signal "noise," necessitating a rigid, properly locked installation.

• Is the housing material chemically inert?

  The stainless steel housing resists common turbine lubricants and process contaminants, ensuring long-term structural integrity in harsh environments.

• How is the conduit fitting utilized?

  The integrated fitting secures protective conduit, shielding the transducer cable from environmental impact and physical abrasion.

• Does this assembly include the proximity probe?

  No, the housing assembly is a mechanical component and does not include the transducer or extension cable.

• Can the housing be used in high-pressure oil cavities?

  Yes, when installed with appropriate thread sealant, the housing maintains the seal integrity of the machine casing.

• How do I confirm the 100 mm length requirement?

  Confirm the machine port depth and the required stick-out distance; the 100 mm length is measured from the mounting thread to the conduit interface.

• Is the housing grounding requirement critical?

  Yes, maintaining a low-impedance ground path is a requirement to minimize RFI/EMI interference on the sensitive eddy-current signal.
