Features:

  • Integrated Proximitor sensor design reduces external hardware requirements
  • PPS thermoplastic housing with reinforced fibers improves structural and electrostatic performance
  • Direct monitor wiring capability simplifies installation and connection layout
Bently Nevada 330801-28-04-105-00-02 is a PROXPAC proximity transducer assembly designed to combine proximity sensing and signal conditioning within a single housing structure. Its external appearance and mounting details are similar to the traditional 31000 and 32000 probe housing assemblies. The integrated Proximitor sensor located inside the housing cover eliminates the need for a separate sensor enclosure. This configuration supports simplified installation and direct system integration.

The mechanical configuration of Bently Nevada 330801-28-04-105-00-02 includes a 40 mm standoff adapter option and a 105 mm probe penetration option. It accepts a noncontacting 3300 XL 8 mm probe with a 1-metre cable installed inside the probe sleeve. The assembly also uses a 3/4-14 NPT mounting thread when the standoff adapter is required. These specifications support structured positioning and mounting consistency within industrial monitoring systems.

The housing of Bently Nevada 330801-28-04-105-00-02 is manufactured from Polyphenylene Sulfide (PPS) reinforced with glass and conductive fibers. This design replaces earlier metal housings while maintaining strength and electrostatic dissipation characteristics. The assembly is rated for both Type 4X and IP66 environments, providing protection in severe operating conditions. Defined power supply requirements and direct field wiring support stable integration into machine monitoring systems.

The 330801-28-04-105-00-02 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
Bently Nevada 330801-28-04-105-00-02 is designed with a structure similar to the 31000 and 32000 proximity probe housing assemblies. It maintains the same external mounting arrangement and accessibility for probe adjustment while integrating additional sensing functionality into the housing itself. The assembly contains its own Proximitor sensor positioned inside the housing cover. This integrated configuration forms a fully self-contained proximity probe system. The model Bently Nevada 330801-28-04-105-00-02 simplifies transducer installation architecture.

The sensing configuration of Bently Nevada 330801-28-04-105-00-02 includes a 3300 XL 8 mm proximity probe with multiple approvals. It accepts one noncontacting 3300 XL 8 mm probe equipped with a 1-metre cable length installed within the probe sleeve. The assembly is configured with a 40 mm standoff adapter option and a 105 mm probe penetration option. These dimensions support standardized positioning and installation alignment. The model Bently Nevada 330801-28-04-105-00-02 maintains consistent mechanical configuration within the PROXPAC series.

The mounting structure of Bently Nevada 330801-28-04-105-00-02 includes a 3/4-14 NPT mounting thread option, required when the standoff adapter option is selected. The fittings option is supplied without fittings and includes two plugs and two washers. This arrangement supports flexible conduit and connection preparation depending on installation requirements. The assembly also eliminates the need for a separate Proximitor housing because field wiring can connect directly between the monitoring system and the PROXPAC unit. The model Bently Nevada 330801-28-04-105-00-02 supports simplified field wiring structure.

The power requirements of Bently Nevada 330801-28-04-105-00-02 specify operation from -17.5 Vdc to -26 Vdc without barriers at a maximum consumption of 12 mA. When barriers are used, the operating range is -23 Vdc to -26 Vdc. Operating above -23.5 Vdc may reduce linear range performance. These electrical specifications define the required operating conditions for the assembly. The model Bently Nevada 330801-28-04-105-00-02 maintains compatibility with defined power supply configurations.

The housing of Bently Nevada 330801-28-04-105-00-02 is manufactured from Polyphenylene Sulfide (PPS), an advanced molded thermoplastic material. The PPS structure incorporates glass and conductive fibers for additional strength and electrostatic dissipation. This material replaces earlier steel and aluminum housing designs used in previous product generations. The housing is rated for Type 4X and IP66 environmental protection. The model Bently Nevada 330801-28-04-105-00-02 is intended for operation in severe environmental conditions.
