The 330881-28-00-061-03-02 is a high-performance eddy current proximity sensor assembly belonging to the PROXPAC XL series. This device is designed to provide accurate, non-contact shaft vibration and current monitoring for rotating machinery.
All-In-One Self-Contained Design
Zero Extension Cables Required
Extreme Temperature Range
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.

Oil & Gas
Resists severe salt spray and moisture while monitoring the high-pressure water injection pumps and oil export pumps.
Pulp & Paper
Safeguards the roller bearings and gearboxes of heavy-duty paper mill dryer cylinders against unscheduled mechanical breakdown.
Petrochemical & Refining
Monitors shaft vibration and thrust position of critical centrifugal compressors and gas turbines in corrosive, hazardous chemical environments.
Liquefied Natural Gas
Provides high-reliability vibration monitoring for cryogenic pumps and boil-off gas (BOG) compressors under ultra-low ambient temperatures.
Nuclear Power
Provides robust, all-in-one machinery protection for cooling water circulation pumps and conventional island turbines.
When using the 330881-28-00-061-03-02 integrated assembly, always follow these critical guidelines. Never hot-swap the device while powered and use ESD protection when handling internal wiring to prevent chip burnout. Precisely calibrate the probe gap voltage during installation to prevent the tip from colliding with the shaft. Lastly, ensure strict waterproof sealing on the housing cover and conduits to block moisture or oil from shorting internal terminals.
It is a Bently Nevada PROXPAC XL Proximity Transducer Assembly, which integrates a 3300 XL 8 mm probe, matched cable, and Proximitor sensor inside a single robust field housing.
How to use the 330881-28-00-061-03-02?
Mount the assembly directly onto the machinery casing or bearing housing via its thread, adjust the probe penetration, and connect field wiring straight from the internal Proximitor to your monitors.
What is the major advantage of using the 330881-28-00-061-03-02?
It eliminates the need for separate extension cables and dedicated external Proximitor housings, significantly simplifying field wiring.
What is the housing material of the 330881-28-00-061-03-02?
It is made of glass-reinforced Polyphenylene Sulfide (PPS), an advanced thermoplastic engineered to effectively dissipate electrostatic charges.
What is the environmental rating of the 330881-28-00-061-03-02 housing?
The heavy-duty housing provides exceptional severe weather protection with IP66 and Type 4X ratings.
