Description

The design of the PROXPAC XL Proximity Transducer Assembly is similar to our 31000/32000 Proximity Probe Housing Assemblies. The assembly offers the same advantages and features as the 31000 and 32000 housings for accessing and externally adjusting proximity probes. However, the housing cover of the PROXPAC XL Assembly also contains its own 3300 XL Proximitor sensor. This design makes the PROXPAC XL Assembly a completely self-contained proximity probe system, and eliminates the need for an extension cable between the probe and its associated Proximitor sensor. It also eliminates the need for a separate Proximitor housing, as the field wiring connects directly between the monitors and PROXPAC XL Assemblies.

Applications

Power plants: Vibration monitoring of steam turbines, feedwater pumps, and fans.

Chemical plants/refineries: Displacement monitoring of reciprocating compressors and large centrifuges.

Steel plants: Monitoring the operating status of heavy machinery such as rolling mills and blowers.

Paper mills: Bearing monitoring of large drying cylinders and drive chains.

Cement plants: Health management of large crushers and conveying equipment.

Competitive Advantage

Corrosion Resistance: The PPS housing replaces the traditional metal housing, offering superior resistance to acids and alkalis.

High Integration: Reduces on-site wiring work, lowering installation complexity and cost.

Interference Resistance: Possesses strong RFI/EMI (electromagnetic interference) resistance, resulting in more stable data.

FAQ

Q: What is the difference between the 330881-28-16-155-03-02 probe and the standard 3300 XL probe?
A: The 330881-28-16-155-03-02 is a "complete package" solution, pre-installing the probe, cable, and preamplifier in an IP66 corrosion-resistant housing. It's ready to install, eliminating the need to purchase a separate preamplifier mounting box.

Q: Why is the housing of the 330881-28-16-155-03-02 probe made of PPS plastic instead of metal?
A: PPS (polyphenylene sulfide) effectively prevents static electricity buildup and is more durable than stainless steel or aluminum in highly corrosive environments such as chemical plants, while also being lighter.

Q: What is the ideal gap for installation of the 330881-28-16-155-03-02 probe?
A: A typical recommendation is 1.27 mm (50 mils), corresponding to approximately -10 Vdc output voltage (for 4140 steel).

Q: Can I replace the internal probe of the 330881-28-16-155-03-02 if the cable is damaged?
A: Yes, the internal components of the 330881-28-16-155-03-02 are fully interchangeable. Replacing the probe or cable will maintain system accuracy.

Q: Does the 330881-28-16-155-03-02 probe support operation in sub-zero temperatures?
A: Yes. Its probe can operate at temperatures as low as -52°C, and the housing can withstand ambient temperatures as low as -51°C.
