Description
The Bently Nevada 24701-34-05-00-043-03-02 features a 303 stainless steel housing and 304 stainless steel tubing, providing excellent corrosion resistance and mechanical rigidity, making it suitable for high-humidity, corrosive, or explosive industrial environments. Its reverse-mount design allows technicians to change or adjust probes without disassembling the machine, significantly reducing downtime and maintenance risks.

The Bently Nevada 24701-34-05-00-043-03-02 configuration includes a 0.5-meter probe cable, a 4.3-inch probe insertion length, and 3/4-14 NPT mounting threads, without adapters. Its CSA explosion-proof certification (Class I, Divisions 1 & 2, Groups C and D) allows for safe deployment in hazardous areas such as oil and gas, refining, and power plants. The housing meets both CSA Type 4 and API 670 requirements for externally mounted probe housings.

The Bently Nevada 24701-34-05-00-043-03-02 integrates seamlessly with the 3300 XL 8mm probe and the Bently Nevada 3500 monitoring system, providing a complete signal link from the rotating axis to the diagnostic system. Its rigid mechanical structure effectively eliminates probe jitter, ensuring high repeatability and accuracy in vibration, displacement, and phase measurements.

On which types of equipment is the Bently Nevada 24701-34-05-00-043-03-02 typically used?
It is used on steam turbines, centrifugal compressors, gas turbines, large pumps, and other critical rotating machinery to monitor shaft vibration, position, and phase.
Can I replace the probe while the machine is running?
Yes. The reverse‑mount design allows probe removal or adjustment without opening the machine, provided that casing pressure and temperature remain within safe limits per site safety procedures.
Does this housing affect measurement accuracy?
No. Its rigid stainless steel construction holds the probe perpendicular to the target, eliminating wobble and ensuring high repeatability for peak‑to‑peak vibration and phase measurements.
Is the Bently Nevada 24701-34-05-00-043-03-02 suitable for outdoor or corrosive environments?
Yes. The stainless steel body, NPT threads, and CSA Type 4 enclosure provide excellent protection against rain, humidity, dust, and salt‑laden atmospheres.
Is it compatible with the Bently Nevada 3500 monitoring system?
Yes. When paired with a 3300 XL 8mm probe, the housing supports standard signal interfaces that work directly with Bently Nevada 3500 and M series monitors.
