Technical Performance Matrix

Eddy-Current Probe Scaling and Rotor Dynamics Tracking

The 8 mm sensing tip applies unified eddy-current probe scaling rules to change magnetic flux variations into direct electrical representations of physical gap changes. This analog mapping loop maintains continuous gap voltage validation (-10 VDC targets) during high-frequency rotor dynamics recording, preventing feedback distortion while supporting long-term machinery diagnostic reporting.

Field Installation Guidelines

• Thread Insertion & Torquing Steps
  • Rotate the 3/8-24 UNF threaded barrel into the matching installation bracket manually until the front face reaches proximity with the target shaft.
  • Ensure a minimum of 5 full thread engagements within the mounting bracket to secure the assembly against structural vibrations.
• Physical Armor Routing
  • Secure the armored stainless steel conduit along rigid machine frames using vibration-damping insulated brackets.
  • Enforce a strict minimum physical bending radius limit of 25.4 mm (1.0 in) along all installation turns.

Engineering Technical FAQ

• What nominal target parameter defines standard gap voltage validation during field balancing?

  The primary instrumentation loop requires a gap voltage validation targeting -10 VDC at the center of the sensor linear range.

• How does the integrated flexible armor cladding affect the routing paths of this transducer?

  The stainless steel armored sleeve protects the coax line but sets a strict minimum routing bend radius of 25.4 mm (1.0 in).

• Can this 1.0 meter proximity probe run without an additional extension cable link?

  No, the complete loop length must match the electrical calibration of the 3300 XL Proximitor sensor, which is usually 5.0 or 9.0 meters total.

• What symptom appears if moisture compromises the miniature coaxial ClickLoc connector terminal?

  Moisture inside the terminal alters coaxial loop impedance, corrupting the eddy-current probe scaling and causing error readouts.

• What is the mechanical purpose of the 0.0 in unthreaded selection code?

  The 0.0 in code provides full exterior threading over the 1.2 in case length, maximizing depth placement flexibility in thin brackets.

• Is external coolant or compressed air mandatory for continuous deployment at maximum range?

  No, the internal components utilize high-temperature polymers rated for continuous exposure up to +177 deg C without external cooling.

• What consequence occurs if the probe tip makes physical contact with a spinning target shaft?

  Mechanical contact destroys the internal coil assembly instantly, forcing the driver output to saturate to its limit.

• How is the coaxial shield isolated from stray machinery frame electrical currents?

  The connector protection sleeve must shield the ClickLoc junction to prevent ground loops from entering the TSI cabinet.
