• Electrical Compatibility: Matches 3300‑XL 5 mm / 8 mm proximity probes and 3300‑XL proximitor sensors. Total transducer‑system length (probe integral cable + extension cable) must strictly match calibrated proximitor system length. Suffix‑00 denotes standard version without international hazardous‑location approvalsBaker Hugh…。

Core Functions

1. Transmits high‑frequency eddy‑current sensor signal between proximity probe and proximitor sensor, maintaining signal integrity for gap‑voltage conversion, radial‑vibration and thrust‑position measurement. Extends physical reach of probe for routing inside turbine and compressor enclosures to proximitor mounting location.
2. Deployed on steam‑turbines, gas‑turbines, centrifugal compressors and other critical rotating‑machinery as part of 3300‑XL transducer set, paired with 3500‑series / 1900‑series monitoring systems for machinery protection and condition‑diagnosis.
3. Must maintain correct total system cable length; mismatched total length will shift sensitivity, degrade linear performance and produce erroneous gap‑voltage readings.
4. The ClickLoc “click‑and‑turn” connector design provides repeatable, low‑contact‑resistance mating between transducer components.
5. Widely used in power‑generation, petrochemical and oil‑gas industrial sites. Distinguished ordering code:‑080‑ defines 8 m length,‑00‑ defines standard cable without armor or connector boots,‑00‑ defines non‑agency variant. Replacement requires re‑verification of total transducer‑system length and gap‑voltage calibration。

Installation Requirements

1. Routing requirement: Route cable separate from high‑voltage power and large‑current motor cables to suppress electromagnetic interference. Avoid sharp bends, crushing, pinching and tensile pulling. Minimum cable bend radius 25.4 mm at all points along cable run本特利。
2. Connector handling: Mate ClickLoc connectors finger‑tight plus maximum 1/8‑turn; over‑torque will damage gold‑plated contact pins. Do not disassemble connector assemblies.
3. Grounding rule: Single‑point shield grounding implemented at proximitor‑sensor end only to eliminate ground‑loop noise.
4. Environmental control: Prevent continuous direct immersion and heavy‑fluid splashing at cable‑junction points; FluidLoc‑type extension cable variant shall be selected for locations with persistent heavy‑oil mist and process‑fluid spray. Outer‑jacket abrasion will cause signal drift or intermittent faults.
5. Pre‑installation visual inspection: Inspect cable jacket for cuts, cracking or abrasion; inspect both‑end ClickLoc connector pins for bending, corrosion or contamination before commissioning. After full transducer assembly, measure static gap voltage to verify valid linear‑range operation.
6. Part‑number cross‑version distinction: 330130‑080‑00‑00 is standard non‑armored 8 m extension cable. Armored, FluidLoc, connector‑boot‑protected variants cannot be interchanged without re‑calculating total system length. Different‑length extension cables are not direct drop‑in substitutes; replacement demands full system‑length validation and gap‑voltage calibration。

Common Failure Modes

‑ Cable‑jacket abrasion, tri‑axial conductor micro‑fracture: intermittent gap‑voltage drift, noisy vibration readings, sporadic signal drop‑out. ‑ Improper bend radius or tensile pull stress: internal conductor damage, gradual signal degradation. ‑ ClickLoc connector pin contamination, corrosion or over‑torque damage: unstable signal connection, high‑frequency noise superimposed on vibration waveform. ‑ Multi‑point shield grounding: ground‑loop induced noise, unstable gap‑voltage output. ‑ Mismatched total transducer‑system length: incorrect sensitivity, offset gap‑voltage, invalid measurement data.
