The 21000-16-10-00-030-00-02 is a Bently Nevada explosion-proof aluminum probe housing assembly featuring an integrated 3300 XL 8mm proximity probe. Fully compliant with API 670 standards, this unit works seamlessly with 3300 XL Proximitor Sensors and extension cables to deliver robust physical protection and stable industrial vibration monitoring in demanding external environments.
Specifications
- Housing Material: Constructed of polyphenylene sulfide (PPS), a high-strength thermoplastic with excellent corrosion resistance.
- Metal Components: Other elements made of corrosion-resistant stainless steel for durability.
- API Compliance: Fully compliant with API 670 Standard for externally mounted proximity probe housings.
- Hazardous Area: Suitable for intrinsically safe hazardous area applications when installed with approved components.
- Probe Type: Accommodates 3300 XL 8 mm probe with 1.0 m (39 in) cable length.
- Fitting: 3/4-14 NPT conduit fitting; overall housing length of 3.0 in (76.2 mm).
System Compatibility and Alternative Models
System Compatibility
- Fully compatible with Bently Nevada 3300 XL Proximitor Sensors and 3300 XL Extension Cables.
Fully interchangeable with legacy non-XL 3300 5mm and 8mm transducer systems in compliance with API 670 standards.
Alternative Models & Differences
- 24701-16-10-00-030-00-02: Utilizes a 303 stainless steel housing body instead of the lighter aluminum body of the 21000 series.
21000-28-10-00-030-00-02: Features a 3300 XL 8mm probe with selectable hazardous area approvals rather than the standard probe option.
164818 Compact Housing: Designed specifically for applications with severe space restrictions, whereas the 21000 series provides a full-sized rugged dome cover.
