Features:

  • Integrated Proximitor® Sensor Eliminates External Extension Cable Requirements
  • Direct Monitor Connection for Short Runs with Junction Box Terminal Access for Longer Distances
  • Reinforced PPS Housing Rated for Type 4X and IP66 Severe Environment Protection
The Bently Nevada 330801-28-00-115-03-02 PROXPAC® Proximity Transducer serves as a fully self-contained proximity probe system within machinery monitoring installations, providing reliable displacement and vibration measurement directly at the equipment location. It continuously integrates a 3300 XL 8 mm probe with multiple approvals and its associated Proximitor® Sensor within a single molded housing, converting mechanical shaft movement into processed electrical signals for distribution to connected monitors. The 330801-28-00-115-03-02 accepts direct field wiring connections for short cable runs while supporting junction box configurations for longer distances, ensuring signal accessibility near the machine skid.

The 330801-28-00-115-03-02 provides essential proximity sensing capabilities common to the entire measurement path, and is a critical component of the vibration monitoring system, directly affecting the proper, normal operation of the overall machinery protection system. One or more 330801-28-00-115-03-02 transducers are required per machine depending on the desired monitoring points and coverage requirements. The 330801-28-00-115-03-02 maintains a 115 mm probe penetration depth with no standoff adapter and is always installed with one M20 fitting and two plugs, utilizing a 3/4-14 NPT mounting thread when the standoff adapter option is specified.

For extended cable run applications, the monitoring system requires a junction box mounted at or near the machine skid to house terminal strips. In addition to standard direct wiring between monitors and the 330801-28-00-115-03-02 for short runs, the extended configuration also performs reliable signal distribution through the junction box. The 330801-28-00-115-03-02 signal routing executes transmission using the internal Proximitor® circuitry housed within the cover assembly.

The 330801-28-00-115-03-02 Bently Nevada PROXPAC® Proximity Transducer may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The 330801-28-00-115-03-02 PROXPAC® Proximity Transducer Assembly is specifically designed to handle the complexities of traditional proximity probe installations that require separate extension cables and external Proximitor® housings. This integrated design solves the problem of cumbersome cable management and multiple component mounting by incorporating its own Proximitor® Sensor inside the housing's cover. As a result, the 330801-28-00-115-03-02 eliminates the need for an extension cable between the probe and its associated Proximitor® Sensor, while also removing the requirement for a separate Proximitor® housing, thereby reducing installation time and potential points of failure.

The 330801-28-00-115-03-02 is engineered for deployment in severe industrial environments where reliable machinery condition monitoring is critical. With its PROXPAC® housing rated for Type 4X and IP66 environments, the 330801-28-00-115-03-02 provides extra protection in harsh conditions. This makes the 330801-28-00-115-03-02 ideal for use on machine skids and rotating equipment where continuous vibration monitoring and shaft position measurement are essential for maintaining operational safety and preventing unplanned downtime.

Regarding installation and integration, the 330801-28-00-115-03-02 follows mounting details similar to the 31000/32000 Proximity Probe Housing Assemblies, allowing for external adjustment of and access to the proximity probe. For short cable runs, field wiring is connected directly between the monitors and the 330801-28-00-115-03-02 PROXPAC® Assemblies. For longer cable runs, a junction box is typically mounted at or near the machine skid to house terminal strips, with field wiring connected to these terminal strips to provide convenient access to Proximitor® signals at a location close to the machine.
