Architecture and Transducer System Matching
The extension cable is an active electrical component of a calibrated tuning loop. The eddy-current measurement system relies on a fixed total electrical length to provide accurate proximity data.
System Length Matching Constraints
The 3300 XL 8mm transducer platform is explicitly calibrated for either a 5.0-meter or 9.0-meter total electrical path length from the probe tip to the Proximitor sensor input terminal.
- 5.0-Meter System Config: Pair this 4.0-meter extension cable (
-040) exclusively with a 1.0-meter proximity probe. - 9.0-Meter System Config: This 4.0-meter extension cable can be deployed in a 9-meter configuration only if combined with a 5.0-meter proximity probe.
- Mismatched component lengths alter the internal LC tank circuit impedance balance, corrupting the Incremental Scale Factor (ISF) and introducing measurement errors.
Engineering Insights: Installation and Lifecycle Maintenance
ClickLoc Connector Assembly Mechanics
The extension cable features gold-plated brass ClickLoc miniature coaxial connectors.
- Procedure: Join the probe and extension cable connectors by pressing them together firmly until they clear the internal detent mechanism with an audible “click.”
- Connectors are designed to be joined finger-tight. Do not use standard pliers or mechanical crimping tools on these gold surfaces, as this deforms the outer contact barrel and alters high-frequency signal transmission.
Routing and Armor Constraints
The stainless steel armor shielding on the -03 option variant protects the FEP core against cutting edges, falling debris, and external pinching forces inside the machine housing. However, the outer armor must not make contact with structural grounding elements or uninsulated live rails. Keep the minimum cable bend radius above 25.4 mm (1.0 in) during conduit routing to prevent internal dielectric degradation.
Connector Protectors and Moisture Prevention
The integrated connector protectors must be positioned over the mated probe-to-cable union point to safeguard against fluid ingress.
- If the junction point resides inside an environment with continuous lube-oil mist or condensing water vapor, seal the connector protectors using self-fusing silicone insulating tape blocks. Do not allow liquid oil to accumulate inside an unprotected connector shell, as oil displacement acts as an insulating dielectric barrier that drops the channel offline into a “Not OK” fault state.
Frequently Asked Questions
Q: Can this 3300 XL extension cable be used to replace a legacy, non-XL 3300 series cable? A: Yes. The 3300 XL extension cable is backward-compatible with older, non-XL 3300 series 5mm and 8mm proximity probe components. When mixed with legacy components, the complete channel tracking resolution will default to the performance envelope of the older hardware generation.
Q: What causes an instantaneous “Not OK” LED indication on the matching Proximitor sensor? A: This alarm state triggers when the DC voltage loop exits nominal operational boundaries (typically dropping below −1.0 V DC or spiking near common). Use a digital multimeter to check the continuity of the cable core and shield. Intermittent open circuits or shorted conductors within the triaxial line will trigger a “Not OK” bypass to block invalid vibration data from tripping the machinery.
Q: Is it permissible to slice or cut this cable to achieve a customized field length? A: Absolutely not. Never cut, shorten, or splice a proximity sensor extension cable. The physical and electrical length is precisely manufactured to maintain the 75 \Omega impedance curve and specific capacitance values. Any modification destroys system calibration and invalidates the hazardous area approvals.
