The Bently Nevada 330881-28-00-125-00-02 is a rugged PROXPAC XL proximity transducer featuring a PPS thermoplastic housing and an 8 mm probe. Designed for IP66 and Type 4X environments, this 125 mm sensor assembly provides high-precision vibration and position monitoring for critical industrial machinery.
The 330881-28-00-125-00-02 represents a significant evolution in proximity sensor housing technology within the Bently Nevada 3300 XL series. By utilizing high-performance Polyphenylene Sulfide (PPS) rather than conventional metallic enclosures, this transducer assembly achieves superior chemical resistance and structural integrity. This molded thermoplastic is specifically reinforced with glass and conductive fibers, which serves the dual purpose of increasing mechanical strength and facilitating effective electrostatic charge dissipation. Consequently, the unit provides a highly stable platform for proximity measurements in volatile or high-interference industrial zones.
Engineered for the most demanding deployments, the housing of this PROXPAC XL transducer carries rigorous Type 4X and IP66 ratings. Therefore, the internal sensitive electronics remain completely shielded against the ingress of pressurized water, fine dust, and corrosive elements. This level of environmental sealing ensures that the proximity system maintains its calibration and accuracy over a long service life, even when exposed to outdoor conditions or wash-down industrial environments.
At the core of the assembly is an 8 mm proximity probe designed for high-resolution vibration and position monitoring of rotating machinery. The specific configuration of this model features a 125 mm probe length and is supplied without a standoff adapter, providing a compact profile for direct mounting. Furthermore, the inclusion of two plugs and washers facilitates a straightforward installation process. Because the 330881-28-00-125-00-02 adheres to multiple global industrial standards and approvals, it serves as a versatile solution for Turbine Supervisory Instrumentation (TSI) and general machinery protection.
