{"title":"21000 31000 And 24701 Proximity Housing Assemblies","description":"\u003cp\u003eThe Bently Nevada 21000, 31000, and 24701 series comprise specialized Proximity Probe Housing Assemblies designed to provide mechanical protection and precise environmental sealing for 3300 and 7200 series proximity transducers. These industrial-grade housings are engineered for critical machinery protection systems, allowing for external probe adjustment and replacement without dismantling the machine casing. The 21000 and 31000 aluminum or stainless steel housings feature explosion-proof ratings and conduit connections, making them ideal for hazardous areas in oil and gas or power generation facilities. Conversely, the 24701 series offers a ruggedized, flexible conduit solution for applications where space is constrained. By maintaining proper probe-to-shaft gap settings and protecting sensitive cable connections from moisture and contaminants, these assemblies ensure the long-term accuracy of vibration and position monitoring in steam turbines, compressors, and large pumps.\u003c\/p\u003e","products":[{"product_id":"24701-28-05-20-024-03-02-bently-nevada-24701-proximity-probe-housing","title":"24701-28-05-20-024-03-02 Bently Nevada 24701 Proximity Probe Housing","description":"\u003ch3\u003e\u003cstrong\u003eProduct Overview\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003e\u003cspan style=\"color: #e67e22;\"\u003e24701-28-05-20-024-03-02\u003c\/span\u003e\u003c\/strong\u003e is a high-performance environmental enclosure from the \u003cstrong\u003e\u003cspan style=\"color: #e67e22;\"\u003eBently Nevada 24701\u003c\/span\u003e\u003c\/strong\u003e series.
