Product Introduction
The Bently Nevada 21000-16-10-15-227-03-02 Proximity Probe Housing Assembly is a precision-engineered component used in machinery condition monitoring and protection systems. Designed specifically for the secure installation of Bently Nevada proximity probes, this housing provides mechanical protection, precise alignment, and environmental sealing for sensors deployed in critical rotating equipment.
This housing assembly is widely utilized in high-performance industrial environments such as gas turbines, compressors, and pumps, where accurate and stable measurement of shaft vibration, position, or movement is critical. The robust stainless-steel construction and IP-rated sealing make this model suitable for both indoor and outdoor installations in highly corrosive, dusty, or wet conditions.
The 21000-16-10-15-227-03-02 variant is one of the extended-length models within the 21000 series, offering additional probe depth range and enhanced mechanical protection for applications requiring deeper reach and exposure resistance.
