OFFICIAL PRODUCT SUMMARY
PROXPAC XL Proximity Transducer Assembly
An integrated proximity measurement assembly that combines a 3300 XL 8 mm probe, Proximitor Sensor, extension cable and protective housing for radial vibration or axial position measurements in demanding environments.
|
Exact configuration: Legacy English code 330800 with option 28 multi-approval 8 mm probe, 4.5 in standoff, 2.0 in penetration, fitting option 03 and 3/4-14 NPT sleeve option 02. The current official datasheet uses 330880 for new English orders and retains 330800 in replacement calculations.
Official datasheet:Document 178554 Rev. E (specifications pages 2-7; ordering pages 8-11; dimensions pages 13-14).

Applications and features
|
|
Integrated measurement
Factory-matched probe, cable and Proximitor Sensor reduce exposed interconnections in the machine area.
|
Severe environments
The weatherproof housing and IP66 / Type 4X rating support industrial installations with moisture and contamination.
|
|
Radial or axial use
The assembly supports shaft relative vibration and position measurements when installed with suitable target geometry.
|
Accessible field wiring
The housing provides a protected termination area while keeping the sensing probe mechanically adjustable.
|
|
Key selection note: This selected configuration has 6.5 in total standoff plus penetration at mid-setting and remains below the 12 in threshold that requires additional sleeve support.

Installation and compatibility
|
|
Mounting thread
Install through the selected 3/4-14 NPT outer sleeve interface into a suitable machine case or bracket.
|
Set depth
The 4.5 in standoff plus 2.0 in penetration produces a 6.5 in mid-setting dimension.
|
|
Sleeve support
Additional sleeve support is not required by the official threshold because the selected total is not greater than 12 in.
|
Counterbore check
At 2.0 in penetration, verify the machine side or rear view and provide a counterbore if required for sleeve clearance.
|
|
Key selection note: Confirm target material, probe gap, conduit arrangement, thread form and available insertion path before installation.

|
Six checks before purchase
|
|
1. How can the exact legacy model be verified?
Require photographs of the assembly label and all order-code fields showing 330800-28-45-020-03-02. Confirm the 4.5 in standoff, 2.0 in penetration and 3/4-14 NPT sleeve against physical dimensions.
|
|
2. How can New, Used or Refurbished condition be distinguished?
Inspect the probe tip, threads, sleeve, housing seal surfaces, terminal area and conduit fittings. New material should not show witness marks, damaged seals, cut leads, corrosion or prior machine installation.
|
|
3. How can supplier legitimacy and reliability be checked?
Verify legal registration, physical address, traceable bank beneficiary, documented test capability and written condition statement. Require the legacy 330800 code and current equivalency discussion to be explicit in the quotation.
|
|
4. What must engineers check before purchase?
Check the 8 mm probe type, -17.5 to -26 VDC supply, 2 mm range, 7.87 V/mm scale factor, 3/4-14 NPT mounting, 6.5 in mid-setting depth and available machine clearance.
|
|
5. What physical evidence should be requested before payment?
Request dated photographs of the nameplate, probe tip, complete sleeve, fitting set, housing interior and connector area, plus measurement images for the selected 4.5 in and 2.0 in dimensions.
|
|
6. Can a current 330880 or another suffix replace this legacy model?
Not without engineering review. The current official document uses 330880 for new English orders but retains 330800 for legacy replacement calculations. Every mechanical dimension, fitting, thread, probe and approval option must be matched.
