Hold the five-metre chain
Match the probe lead and extension cable to the five-metre sensor rather than selecting by connector appearance.

Exact-model decision context
Long-range differential-expansion work depends on the complete transducer chain, not the conditioner alone. 330878-50-00 is the panel-mount Proximitor Sensor for the documented five-metre 3300 XL 50 mm system.
The matched probe, extension cable and sensor establish the published scale factor and linear range. During replacement, keep the existing total electrical length, target arrangement and mounting method under review before applying power.
Panel mounting also makes cabinet preparation part of the job. Confirm the mounting footprint, isolation hardware, field wiring and available service clearance, then record all component labels for commissioning and future maintenance.
Checks that move the order forward
Match the probe lead and extension cable to the five-metre sensor rather than selecting by connector appearance.
Confirm cabinet space, mounting hardware, isolation and access for wiring checks before the outage.
Verify target geometry and probe gap before treating an output change as a monitor calibration problem.

Two model-relevant engineering themes
Use only the supported 50 mm probe and extension-cable combination whose total electrical length matches the five-metre sensor.
Provide the documented panel mounting, electrical isolation, field wiring and target arrangement before setting the operating gap.
Stop and release boundary
Do not use the sensor to compensate for an incorrect probe, cable length or target geometry. Stop commissioning when the component labels or five-metre chain cannot be reconciled with the official system instructions.
Supported task and system role
Within a complete 3300 XL 50 mm system, the sensor supports long-range differential-expansion measurement on large rotating machinery where the documented target and mechanical arrangement are provided.
Buyer, installer and engineer situations
It can be considered when the installed probe and extension cable are the supported 50 mm components and their total electrical length is five metres. Compare all three labels and the target arrangement before replacement.
Confirm the mounting footprint, isolation hardware, cabinet clearance, power and signal wiring. Keep enough access to inspect terminals and record the final wiring.
A changed probe gap, disturbed target alignment, wrong total cable length, damaged connector or wiring fault can change the output. Correct those causes before adjusting monitor scaling or alarms.
No. Option 00 does not request an agency approval; site classification and installation acceptance must be checked separately against applicable official records.
Read the complete labels and confirm that the parts belong to the supported 3300 XL 50 mm family and make the five-metre total. Similar connectors do not prove a matched chain.
Send the sensor, probe and extension-cable labels, target and mounting drawings, required system length, quantity, destination and clear cabinet photographs.
