• Turbine and compressor radial vibration monitoring

• Keyphasor® speed and phase reference signal measurement

• Machinery condition monitoring in petrochemical plants

• High-temperature rotating machinery

• Installation in hazardous or wet environments with IP66/NEMA 4X protection

Advantages

• External probe access for maintenance without disassembly

• Compliant with API 670 standards

• PPS housing with high strength and corrosion resistance

• Intrinsically safe when used with certified transducer/barrier combinations

• High-impact durability and pressure sealing

• Multiple configuration options with standoff adapters and probe lengths

Technical Specifications

Frequently Asked Questions (FAQ)

Q1: What type of probes are compatible with the 31000 housing?

A1: It supports Bently Nevada 3300 XL 8 mm, 11 mm, and NSv probes with multiple agency approvals.

Q2: Is this housing explosion-proof?

A2: No. The 31000 is designed for intrinsic safety but not explosion-proof use. For explosion-proof models, use CA21000 or CA24701.

Q3: Can the probe be accessed without disassembling the machine?

A3: Yes, the housing allows for external probe access, gap adjustment, or replacement.

Q4: What material is used for the housing?

A4: The housing is made of PPS (Polyphenylene Sulfide) with stainless steel components.

Q5: Is the housing suitable for steam or hot water environments?

A5: Short-term exposure (up to 1 week at 95°C) is acceptable, but long-term exposure may degrade strength.

Q6: Does it comply with API standards?

A6: Yes, it is fully compliant with API 670 for externally mounted proximity probe housings.

Q7: What environmental protection ratings does it have?

A7: It has IP66 and NEMA Type 4X ratings for dust and water resistance.

Q8: Can this housing be used in hazardous areas?

A8: Yes, when installed with approved transducer systems and intrinsic safety barriers.

Q9: What is the impact resistance certification?

A9: It can withstand up to 7 Joules impact per CSA and BASEEFA certification.

Q10: How is the probe cable connected within the housing?

A10: The probe cable is connected internally and protected via stainless steel fittings and sealing components.
