Description

The 21000-16-05-00-084-04-02 is an aluminum Proximity Probe Housing Assembly designed for external mounting of eddy-current proximity probes. This configuration includes a 3300 XL 8 mm probe (Option 16), a 0.5 meter (20 in) probe cable (Option 05), and an 8.4 inch (213 mm) probe penetration length (Option 084). It features a 3/4-14 NPT mounting thread (Option 02) and is configured with a 3/4-14 NPT plug fitting (Option 04) for conduit sealing.

This assembly provides a protective enclosure for probes in industrial machinery environments, ensuring compliance with API 670 standards for externally mounted proximity probe housings. The unit consists of an aluminum housing body, a probe sleeve of the specified penetration length, internal O-rings, and required fittings. It is engineered for applications where secure, robust probe mounting and environmental protection are required for vibration and axial position measurement systems.

Features

  • Housing Material: Aluminum body with 304 stainless steel sleeve
  • Probe Type: 3300 XL 8 mm proximity probe
  • Cable Length: 0.5 m (20 in)
  • Probe Penetration Length: 8.4 in (213 mm)
  • Fittings: One 3/4-14 NPT plug
  • Mounting Thread: 3/4-14 NPT
  • Compliance: API 670 standard for externally mounted proximity probe housings
  • Certifications: CSA explosion-proof rated for hazardous area applications (when ordered with appropriate configurations)

Applications

  • Power generation machinery
  • Oil and gas rotating equipment
  • Petrochemical and refinery monitoring systems
  • Water and industrial pumping systems
  • Turbines, compressors, and pumps requiring external probe mounting
