Applications & Use Cases

Engineers often choose the 21000-34-05-00-030-04-02 for vibration monitoring on rotating machinery like pumps, compressors, and turbines. Its CSA Type 4 enclosure rating makes it suitable for outdoor installations exposed to dust and water. The API 670 compliance ensures it meets industry standards for external mounting. For hazardous area use, the selectable approvals reduce the need for additional enclosures.

Installation & Setup

Mount the housing using the 3/4-14 NPT thread option. Ensure the probe penetration of 3.0 in matches the target gap. The 0.5 m cable length allows connection to nearby junction boxes. Use the included 3/4-14 NPT plug to seal unused ports. Always follow Bently Nevada's installation manual for proper torque and alignment.
