21000-16-10-00-109-03-02 Bently Nevada 21000 Probe Housing Stock

Product Overview: Bently Nevada 21000-16-10-00-109-03-02

The Bently Nevada 21000-16-10-00-109-03-02 provides explosion-proof housing for eddy current proximity probes.

Engineers install this 21000 Series assembly on externally mounted machinery probe ports.

It includes a reverse-mount 3300 XL 8 mm probe inside an aluminum body.

The 304 stainless steel sleeve protects delicate probe components in harsh environments.

This housing fully complies with API 670 standards for machinery protection systems.

Technical Specifications

Model Comparison & Engineering Guidance

Select the correct sleeve penetration depth to position probe tips accurately.

Always check process vessel mounting threads before ordering housing hardware.

Typical Applications & Diagnostic Capabilities

Refineries install the 21000-16-10-00-109-03-02 housing on high-pressure boiler feed pumps.

Engineers use it on gearboxes, steam turbines, and motor bearings in hazardous areas.

The rigid sleeve maintains fixed probe tip gaps during severe machine vibration.

This enables accurate measurement of shaft position, axial displacement, and dynamic vibration signals.

Global PLC Spare HUB's Insight

During a turnaround at a chemical plant, oil leaked through an unsealed probe port.

The original housing failed to withstand ambient vapor exposure and thermal expansion.

Our engineering team recommended installing the Bently Nevada 21000-16-10-00-109-03-02 assembly.

The O-ring seals and cable seal grip completely prevented hazardous fluid egress.

The explosion-proof housing maintained full API 670 compliance throughout three years of continuous operation.

Frequently Asked Questions (FAQ)

Q: How do I adjust probe tip gap inside the 21000 housing?

A: Loosen the probe sleeve locknut to thread the reverse mount probe forward or backward.

Q: Is the 21000 housing suitable for hazardous outdoor locations?

A: Yes, the aluminum housing carries CSA Type 4 rating for explosion-proof outdoor environments.

Q: What cable diameters fit the included cable seal grip fittings?

A: The fitting option handles cable sizes from 1/8 inch up to 3/8 inches using grommets.

Q: Can I replace the internal reverse mount probe without removing the housing?

A: Yes, unscrew the dome cover to access and replace the reverse mount probe directly.

Q: How does API 670 compliance affect housing selection for turbomachinery?

A: API 670 mandates external mounting accessibility, explosion-proof ratings, and standardized probe protection.
