Features:

  • Full API 670 Standard Compliance for Critical Machinery Protection
  • Explosion-Proof CSA Type 4 Certified Enclosure for Extreme Environments
  • Streamlined Direct-Mount Modular Design with Extended-Thread Reinforcement
The Bently Nevada 21000-00-00-00-41-04-02 is meticulously engineered to satisfy the rigorous design guidelines of the American Petroleum Institute’s API 670 standard. This guarantees the assembly provides the precise concentricity, alignment stability, and extreme structural rigidity required to eliminate false probe readings or micro-vibration interference on high-speed turbines and compressors.

Constructed with a heavy-duty aluminum body, the Bently Nevada 21000-00-00-00-41-04-02 features robust industrial O-rings providing an absolute weather-tight seal certified to CSA Type 4 standards. This protection shields your sensing equipment against dust ingress, moisture, heavy wash-downs, and corrosive oil-and-gas fumes while maintaining total flame-path and explosion containment.

The Bently Nevada 21000-00-00-00-41-04-02 features a specialized 3/4-14 NPT mounting thread option precision-machined with 5 to 7 full threads, vastly exceeding standard NPT requirements. This critical enhancement increases mechanical mounting strength and stiffness at the machine case, preventing hardware loosening and simplifying probe calibration tasks in high-vibration field applications.

The 21000-00-00-00-41-04-02 Bently Nevada Proximity Probe Housing Assembly may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
