Typical Application Scenarios & Equipment Compatibility
Machinery protection systems on large industrial turbomachinery utilize this assembly. Compatible equipment includes heavy steam turbines, centrifugal compressors, gas turbines, and large industrial pumps requiring precise vibration and axial position monitoring.
Diagnostic Capabilities & Signal Integrity
The assembly maintains mechanical stability to prevent spurious vibration signals caused by housing resonance. Thread seals and O-rings protect internal connections from moisture and corrosive agents, ensuring uninterrupted voltage or current output signals from the enclosed proximity probe.
Global PLC Spare HUB's Insight & Field Experience
Instrument technicians should apply approved thread sealants carefully on the 3/4-14 NPT connections to maintain explosion-proof integrity during retrofits. In high-vibration compressor setups, verifying proper torque on the internal mounting brackets prevents micro-shifts in probe gap measurements.
Model Selection & Cross-Reference Comparison
When engineering vibration monitoring loops, comparing similar housing variants ensures proper mechanical fit. Review the alternative configuration 21000-16-10-00-052-03-02, which utilizes a longer 5.2-inch probe penetration depth (suffix 052) and a 16 probe option variant. Select the penetration depth matching your machine casing wall thickness and clearance requirements.
