21000-16-10-00-086-03-02 | Bently Nevada 8.6 in Probe Housing Assembly

Understanding the 21000-16-10-00-086-03-02 Proximity Probe Housing Assembly

When unplanned downtime threatens your production targets, the 21000-16-10-00-086-03-02 from Bently Nevada provides a robust solution for vibration monitoring. This 21000 series housing assembly is engineered for hazardous area use, with CSA Type 4 enclosure certification and explosion-proof ratings. By integrating a 3300 XL 8 mm probe with a 1.0 m cable, it delivers precise proximity measurements that help prevent costly equipment failures.

Key Features and Technical Specifications

• Probe Option: 3300 XL 8 mm probe with connector for accurate sensing.
• Cable Length: 1.0 m (39 in) cable for flexible installation.
• Probe Penetration: 8.6 in penetration depth for optimal positioning.
• Fitting Option: Includes one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and a cable seal grip with grommets for various cable sizes.
• Mounting Thread: 3/4-14 NPT for secure attachment.
• Material: Aluminum body with 304 stainless steel sleeve for durability.
• Weight: 1.1 kg (2.4 lb) typical, without fittings.
• Maximum Dimension: 32.9 in (83.5 cm) with visible probe.

One distinctive spec is the 8.6 in probe penetration, which allows the sensor to reach deeper into machinery without compromising signal integrity. This reduces installation time and minimizes the risk of misalignment, directly lowering maintenance costs.

Real-World Applications and Cost Benefits

In rotating machinery such as turbines and compressors, the 21000-16-10-00-086-03-02 continuously monitors shaft vibration and position. Early detection of abnormal readings prevents catastrophic failures, reducing repair expenses by up to 30%. Furthermore, its explosion-proof design eliminates the need for additional protective enclosures in hazardous environments, saving both capital and operational costs.

Installation and Setup Guidance

Mount the housing using the 3/4-14 NPT thread and connect the probe cable through the included seal grip. Ensure the probe sleeve length matches the required penetration depth. For optimal performance, follow the manufacturer's manual for torque specifications and alignment procedures.

Maintenance and Reliability Insights

Periodically inspect the housing for signs of corrosion or damage, especially in harsh environments. The aluminum and stainless steel construction resists wear, extending service life. Regular calibration checks every 12 months help maintain accuracy, reducing the risk of false alarms and unplanned downtime.

Compatibility and Integration Options

This housing assembly works with Bently Nevada monitoring systems that accept 3300 XL 8 mm probes. It integrates seamlessly with existing vibration monitoring networks, supporting both new installations and retrofits. For specific system compatibility, consult the official datasheet.
