21000-28-05-00-040-03-02 is a Bently Nevada proximity probe housing assembly designed for harsh industrial environments such as power plants, oil refineries, and rotating machinery systems. This assembly protects proximity probes and ensures stable signal transmission under vibration, temperature variation, and contamination exposure. It plays a critical role in vibration monitoring systems by maintaining probe alignment and shielding sensitive components. Engineers rely on this housing to reduce signal noise and prevent premature probe failure. Its robust construction supports continuous operation, helping maintenance teams minimize unplanned downtime and extend asset lifecycle.
The model code defines the exact configuration of the housing assembly:
28 = 3300 XL 8 mm probe with multiple approvals
05 = 0.5 metre probe cable length
00 = No standoff adapter included
040 = 4.0 inch probe penetration depth
03 = Fittings kit includes one 3/4-14 NPT plug, one reducer, and cable seal grip with multiple grommets
02 = 3/4-14 NPT mounting thread
This structured coding ensures precise selection for specific installation requirements.
| Parameter | Value |
|---|---|
| Model | 21000-28-05-00-040-03-02 |
| Brand | Bently Nevada |
| Origin | USA |
| Weight | 2 kg |
| Dimensions | Standard industrial housing form factor |
| Operating Temp | -40 to 100 deg C |
| Power Consumption | Not applicable (passive mechanical component) |
| Material | Aluminum body with 304 stainless steel sleeve |
| Probe Compatibility | 3300 XL 8 mm series |
| Mounting Thread | 3/4-14 NPT |
Is this model still in production?
No. Bently Nevada replaced it with 21000-16-05-00-040-03-02, which offers updated compliance and improved availability.
Can I use this housing with other probe types?
It supports 3300 XL 8 mm probes. Verify compatibility before using other probe series.
What is the main installation risk?
Improper sealing or incorrect thread engagement may cause moisture ingress and signal instability.
Does it require power input?
No. This assembly is a passive mechanical protection component.
Ensure proper thread sealing using industrial-grade thread sealant to prevent oil or moisture leakage.
Maintain correct probe gap voltage during installation to avoid signal distortion.
Use appropriate torque when tightening fittings to avoid thread damage or deformation under vibration.
