21022-12-10-022-01 | Bently Nevada Dual Axial Probe Housing Assembly

Introduction to the 21022-12-10-022-01

When you need reliable axial thrust position monitoring, the 21022-12-10-022-01 from Bently Nevada offers a robust solution. This dual axial probe housing assembly mounts externally on the machine case near the thrust bearing. It allows both probes to observe the shaft end for accurate position measurement. The housing meets API 670 standards for axial thrust position transducer housings. This ensures compatibility with industry requirements.

Key Features of the 21022-12-10-022-01

• Dual 3300 XL 8 mm proximity probes for redundant measurement.
• Probe cable length of 1.0 meter (39 inches) for flexible installation.
• Probe penetration option of 2.2 inches for precise gap setting.
• Includes one 3/4-14 NPT fitting and three 3/4-14 NPT plugs as a kit.
• Aluminum alloy housing (sand cast, 0.3% copper free) with 304 stainless steel sleeves.
• Weight of 3.6 kg (8 lb) for easy handling.
• External mounting allows probe adjustments without machine disassembly.
• Removable cover provides access for setting probe gaps.

The dual probe design enhances reliability by providing two independent measurements. This reduces the risk of unplanned downtime. The 8 mm probe option ensures compatibility with standard proximity systems.

Applications and Use Cases

In industrial settings, the 21022-12-10-022-01 is ideal for monitoring axial thrust position in turbines, compressors, and pumps. The external mounting protects probes from dust and splashing liquid. This makes it suitable for harsh environments. For example, in a steam turbine, the assembly helps detect thrust bearing wear early. This prevents catastrophic failure. The API 670 compliance ensures it meets the rigorous demands of the oil and gas industry.

Installation and Setup Guide

Mount the housing on the machine case using four standard machine screws. The probes install through two 3/4-inch NPT threaded holes. The fittings kit is supplied separately and is not pre-installed. Adjust the probe gaps through the removable cover after mounting. Ensure the probe penetration depth matches the 2.2-inch option for optimal performance. Follow Bently Nevada’s manual for wiring and calibration steps.

Maintenance and Reliability

Regularly inspect the housing for signs of corrosion or damage. The aluminum alloy and stainless steel construction resist environmental wear. Check the probe cables for cuts or abrasions. Periodically verify the probe gaps using the removable cover. This proactive approach extends the assembly’s service life and maintains accuracy. The robust design minimizes maintenance frequency, reducing total cost of ownership.

Compatibility and Integration

The 21022-12-10-022-01 works with Bently Nevada 3300 XL 8 mm proximity probes and extension cables. It integrates with Bently Nevada monitoring systems for seamless data acquisition. The NPT fittings allow connection to standard industrial piping. Ensure the system supports the 1.0-meter probe cable length for proper signal transmission.
