Technical Specifications

Engineering Advantages

Seamless Integrated Design

The 330880-16-0-75-00-02 streamlines installation by combining the probe and the Proximitor sensor into a single PPS housing. This architecture removes the vulnerability of external intermediate cables and specialized enclosures, directly addressing the pain point of signal loss in complex industrial layouts.

Extreme Environment Resilience

The Polyphenylene Sulfide (PPS) housing material delivers superior chemical resistance and mechanical strength. This material choice enables the assembly to dissipate electrostatic charges while meeting IP66 and Type 4X ratings. Consequently, the sensor effectively resists corrosion, water ingress, and dust infiltration in the harshest factory conditions.

Simplified External Maintenance

This radial mount assembly allows technicians to adjust or replace the probe from the exterior of the machine. This design prevents unnecessary machinery disassembly during routine maintenance cycles, significantly reducing downtime for vibration sensor calibration or troubleshooting.

Electromagnetic Interference Shielding

The advanced housing design and integrated electronics minimize the impact of EMI/RFI. This ensures that the 3300 XL Proximitor® delivers a clean, linear signal to the monitoring system, even when installed near high-voltage motors or variable frequency drives (VFDs).

FAQs

Does this assembly require a separate Proximitor sensor?

No. The 330880-16-0-75-00-02 features a built-in 3300 XL Proximitor® sensor. This integrated approach simplifies the bill of materials and reduces the number of potential failure points in the measurement chain.

How do I adjust the probe gap without disassembling the housing?

The PROXPAC XL design permits external access. Technicians can loosen the mounting fittings to adjust the probe penetration or gap relative to the shaft, facilitating quick calibration with a digital voltmeter (DVM) via the system output.

Is the PPS housing suitable for corrosive chemical environments?

Yes. Polyphenylene Sulfide (PPS) offers excellent resistance to a wide range of industrial chemicals, fuels, and solvents, making this assembly ideal for petrochemical and refinery applications where standard metallic housings might suffer from accelerated corrosion.
