Bently Nevada 21000-28-10-000-102-03-02 Conjuntos de Carcasa de Sonda de Proximidad

Description

The 21000-28-10-000-102-03-02 is an all-metal, externally mounted proximity probe housing assembly engineered by Bently Nevada for industrial machinery protection systems. Constructed with a robust aluminum body and a durable 304 stainless steel sleeve, this assembly provides secure, external access to proximity probes and their corresponding extension cables. It features a dome cover that screws firmly into the housing body, integrated threaded ports for conduit connections, internal O-rings, and a reliable thread seal. This specific deployment integrates a 3300 XL 8mm probe configured with selectable hazardous area approvals to supply precise eddy-current sensor inputs. The entire assembly is purpose-built to comply with the stringent American Petroleum Institute (API) 670 Standard for externally mounted sensor systems, ensuring uninterrupted monitoring of vital parameters like shaft vibration and position across heavy industrial machinery.

Features

• External accessibility permits gap adjustment and full probe replacement without requiring complex disassembly of the machine case.
• Heavy-duty aluminum body paired with a 304 stainless steel sleeve delivers exceptional mechanical integrity in harsh plant settings.
• Fully compliant with the American Petroleum Institute (API) 670 Standard for externally mounted proximity probe housings.
• Complete structural assembly including a screw-in dome cover, threaded conduit ports, dual O-rings, and dedicated thread seals.
• Engineered mounting thread with 5 to 7 full threads to significantly increase structural installation strength and overall stiffness.

Applications

• External vibration and position monitoring on gas and steam turbines
• Hydrocarbon processing and petroleum refinery rotating equipment protection
• Centrifugal compressor and high-pressure pump shaft observation
• Large industrial electric motor and generator bearing path monitoring
• Heavy-duty fans and blower monitoring in power generation plants

Installation Guidelines

• Sleeve Inspection: Before finalizing installation, verify that the total sleeve length does not introduce mechanical stress. Sleeve lengths longer than 304 mm (12 inches) demand secondary sleeve support to mitigate excessive vibration.
• Penetration Range: Utilize the dynamic adjustment range of Option D, which provides 13 mm (+/- 0.5 in) of axial travel to accurately establish target distance.
• Case Counterboring: For probe penetration lengths designed between 1.0 and 2.0 inches, consider a local counterbore in the machine housing to minimize unwanted side-view or rear-view proximity interference.
• Cable Management: Carefully dress the inner probe cable during enclosure closure. Avoid excessive cable loops within the main housing body to completely eliminate any damage when screwing the primary dome cover back into position.
• Environmental Protection: Ensure all associated O-rings and structural thread seals are correctly aligned and uncompromised during field installation to maintain structural Type 4 sealing capability.

Compliance and Certifications

• RoHS: Complies with European Community Directive: ROHS Directive 2011/65/EU.
• Industry Standards: Fully compliant with the American Petroleum Institute's (API) 670 Standard.
• Enclosure Security: Certified as a CSA Type 4 enclosure.
