Applications and Use Cases for the 21000-34-00-15-095-04-02

This housing assembly is ideal for vibration monitoring in turbines, compressors, and pumps. It meets API 670 standards for externally mounted proximity probes. The CSA Type 4 enclosure rating ensures protection in harsh environments. Maintenance teams use it to reduce unplanned downtime through continuous shaft position monitoring.

Installation and Setup of the Bently Nevada Housing Assembly

Mount the 21000-34-00-15-095-04-02 using the 3/4-14 NPT thread for a secure fit. Attach the standoff adapter to achieve the required 1.5 in offset. Connect the probe cable (1.0 m length) to the connector protector. Ensure the dome cover is tightened to maintain the explosion-proof seal. Always follow the manufacturer's manual for torque specifications.

Maintenance and Reliability of the 21000-34-00-15-095-04-02

Regularly inspect the O-rings and thread seal for wear. Verify the dome cover remains secure to preserve the CSA Type 4 enclosure rating. The aluminum body resists corrosion, while the stainless steel sleeve protects the probe. Periodic checks help maintain measurement accuracy and extend service life.
