Technical Specifications Matrix

Eddy-Current Probe Scaling and Rotor Dynamics Calibration

The 330104-00-04-90-02-00 probe relies on a precise eddy-current probe scaling factor of 7.87 V/mm to execute raw voltage translation from mechanical micro-movements. During field calibration routines, gap voltage validation (-10 VDC targets) must be verified at the central operating zone of the target rotor dynamics assembly. To minimize electronic noise and retain target linear precision, the 9.0 m system loop matching eliminates cross-talk suppression failures when the probe head operates adjacent to high-speed journal bearings or concurrent sensor installations.

Supply Kit Components

• One (1) 330104-00-04-90-02-00 integrated 8 mm proximity probe and 9.0 m cable assembly

• Two (2) Lock washer positioning fasteners

• One (1) Fluorosilicone connector protection insulating boot

Mechanical Mounting and Alignment Protocol

Mechanical insertion requires mounting the probe head via a bracket or slide housing until an inline voltmeter tracking the Proximitor terminal block registers a precise gap voltage validation target of -10 VDC. Maintain a minimal physical clearing radius of 15 mm around the 8 mm probe tip to prevent adjacent casing metal from altering the eddy-current probe scaling characteristics. Ensure the 9.0 m flexible cable is routed through independent, isolated metallic conduit channels, terminating the outer shield braid strictly at the single-point monitoring rack instrumentation ground to isolate induced noise.

Packaging and Shipping Criteria

Delivery time: 3-5 days when payment finish through specialized DHL/FEDEX/UPS express loops. The hardware is locked inside rugged anti-static industrial packaging using custom-molded interior high-density structural foam pads to guarantee protection of the calibrated coaxial coils and internal micro-machined target windings during field transport.

Engineering FAQ

Q: Can the 9.0 m integrated coaxial line be shortened or spiced with generic field wiring?

A: No. The internal inductance and capacitance metrics are matched specifically to the 3300 XL Proximitor sensor calibration framework. Shortening the line disrupts the calibrated eddy-current probe scaling loop and generates severe measurement calculation faults.

Q: Is this proximity probe hardware capable of structural hot-swap actions while energized?

A: Electrical disconnection of the probe coaxial lead from the Proximitor sensor can be performed under live voltage conditions; however, this instantly forces the driver loop into an open-circuit state, triggering a "NOT OK" system fault on the monitoring module.

Q: What structural material provides the default calibration target for the 8 mm tip?

A: The factory scaling baseline is set for AISI 4140 steel targets. Using targets made of alternative metallurgy, such as stainless steel or aluminum, requires recalibration of the Proximitor loop due to differences in magnetic permeability.
