Oiltech Controls’s Insight – Engineering Perspective

• The self-contained design removes extension cable failures – a common weak point in traditional setups.
• PPS housing with conductive fibers provides superior corrosion resistance compared to aluminum housings.
• IP66 rating ensures reliable operation in wash-down or high-humidity zones.
• The 3300 XL 8mm probe offers high interchangeability – swap probes without recalibration.
• This assembly is a drop-in upgrade for 31000/32000 housings with added sensor integration.

Typical Equipment Compatibility

• Steam turbines – radial vibration and thrust position monitoring
• Centrifugal compressors – shaft vibration and axial position
• Large pumps and motors – bearing vibration monitoring
• Generators and gearboxes – critical shaft dynamics
• Any rotating machinery requiring 3300 XL 8mm proximity probe systems

Professional FAQ – Experience-Based Q&A

• Q: What is the main advantage of the PROXPAC XL over a separate Proximitor system?
• A: It eliminates the extension cable between probe and sensor – a common failure point in high-vibration areas. This reduces downtime and simplifies troubleshooting.
• Q: Can I use this transducer with an older 3300 monitor (non-XL)?
• A: Yes, but verify the power supply and scale factor. The 3300 XL has slightly different ISF (7.87 V/mm) vs older 3300 (7.87 V/mm is identical, but interchangeability is improved). Always check the monitor’s input range.
• Q: What is the practical maximum cable length for reliable signal?
• A: While 305m is specified, we recommend staying under 200m to minimize high-frequency rolloff. For long runs, use low-capacitance triax cable and verify with a signal analyzer.
• Q: How do I handle the gap setting for first-time installation?
• A: Set initial gap at 1.27 mm (50 mils) using a feeler gauge or micrometer. Adjust to obtain -10 Vdc output (mid-scale) at room temperature. Re-check after machine reaches operating temperature.
• Q: What should I check if the output drifts over time?
• A: First inspect the probe cable and ClickLoc connector for corrosion. Then verify the power supply stability. Drift can also occur from target surface changes (e.g., coating or rust). Re-gap if necessary.
