Bently Nevada 21000-16-10-00-025-04-02 21000 Series Proximity Probe Housing Assembly

Description

Engineered for robust mechanical protection of critical machinery sensors, the 21000-16-10-00-025-04-02 proximity probe housing assembly provides an environmentally sealed enclosure for displacement and vibration measurements. This unit allows external installation, adjustment, and replacement of transducer systems while safeguarding the probe from physical damage and harsh industrial exposure.

The construction combines a lightweight yet durable aluminum housing body with a high-strength 304 stainless steel sleeve, ensuring longevity and resistance to corrosion. This specific configuration is optimized for a 3300 XL 8 mm probe with a 1.0-meter cable option, utilizing a 3/4-14 NPT mounting thread to establish a secure machine interface without requiring a standoff adapter.

Features

• Constructed with an aluminum housing body and a 304 stainless steel sleeve for optimal durability.
• Provides physical and environmental shielding for proximity sensors in hazardous or demanding locations.
• Facilitates direct penetration adjustments of the probe assembly up to 2.5 inches.
• Features one 3/4-14 NPT plug configuration to seal unused mechanical access ports.
• Simplifies transducer replacement and maintenance procedures without dismantling major machine components.

Applications

• Industrial turbomachinery monitoring (steam and gas turbines).
• Petrochemical and oil and gas rotating equipment protection.
• Heavy industrial blower, compressor, and pump vibration systems.
• Hydroelectric and thermal power generation plant installations.

Installation Guidelines

• Apply thread sealant to the 3/4-14 NPT mounting threads to prevent leakage of machine lubricants or fluids.
• Verify that the 2.5-inch probe penetration depth aligns with target rotor or shaft clear spacing requirements before final torque application.
• Ensure that the conduit routing and external connections are properly sealed to maintain environmental protection ratings.
• Avoid excessive torque during housing installation to prevent damage to the machine casing and the internal sleeve.
