Proximity Probe Housing Assembly

21000-16-05-00-090-04-02:

This is a 21000 Proximity Probe Housing Assembly manufactured by Bently Nevada (Baker Hughes). 21000-16-05-00-090-04-02 assembly features a flush mount configuration with a 9.0-inch probe penetration length. It includes a 3/4-14 NPT mounting thread and a single 3/4-14 NPT plug (Option 04) for the conduit entry.

Parameters - 21000-16-05-00-090-04-02

Probe Type:3300 XL 8 mm (Reverse Mount)
Probe Cable Length:0.5 meter
Mounting Thread:3/4-14 NPT (Machined for 5-7 full threads for increased stiffness)
Housing Material:Aluminum (Body), 304 Stainless Steel (Sleeve)

Application Areas - 21000-16-05-00-090-04-02

Radial Vibration Monitoring: Steam turbines, gas turbines, centrifugal compressors, pumps, and generators.
Keyphasor (Phase Reference/Speed) Measurement
Industry Compliance & Environment: Machinery Protection Systems in the Oil & Gas, Petrochemical, and Power Generation industries.

Important Cautions - 21000-16-05-00-090-04-02

1. Sleeve Resonance Risk:Probe penetration is 9.0 inches (228.6 mm) . This is approaching but still under the 12-inch (304.8 mm) maximum unsupported length limit.
2. Connector Protector Absence:Option A:16 specifies the standard 3300 XL 8mm probe without the connector protector. The RF connector at the end of the probe cable will be exposed inside the housing.
3. Low-Temperature Pressure Seal Risk: Exposing the 3300 XL probe to temperatures below -34°C (-30°F) may cause premature failure of internal pressure seals.
