Technical Specifications

Installation & Environmental Protection

1. Precise Measurement: The 21000-16-10-00-066-03-02 offers a 6.6-inch penetration depth, which is adjustable via calibration to achieve the exact probe gap required for your machinery. This ensures the transducer is optimally positioned relative to the target shaft for maximum sensitivity.

2. Advanced Sealing: This assembly is IP67 certified, providing complete protection against dust ingress and temporary immersion in water. The package includes three specialized cable seal grips for various diameters (1/8" to 3/8"), ensuring a gas-tight, weather-proof seal at the conduit entry points.

3. Rugged Construction: Built to withstand harsh plant conditions, the assembly features a dome cover with 304 stainless steel O-rings and is rated for a static pressure of up to 150 psi. The 3/4-14 NPT mounting thread ensures a secure, leak-proof connection to the machine case in accordance with API 670 guidelines.

Engineering Advantages

The Bently Nevada 21000 series is the preferred choice for vibration professionals worldwide. By utilizing high-grade 304 stainless steel for the probe sleeve and providing hazardous area approvals (Ex ia IIC T4 Ga), this housing ensures that critical monitoring data remains uninterrupted even in volatile atmospheres. The inclusion of NPT plugs and reducers in the standard kit allows for flexible field installation across a variety of conduit configurations.

Technical FAQs

Q1: What is the benefit of the IP67 rating for this housing?
A1: The IP67 rating ensures the internal proximity probe is protected from heavy rain, wash-downs, and dusty environments, preventing signal degradation and short circuits.

Q2: Is this housing assembly compatible with high-temperature applications?
A2: Yes, the 21000-16-10-00-066-03-02 is rated for an operational temperature range of -50°C to 150°C, making it suitable for gas turbines and steam-related machinery.

Q3: How much can the penetration depth be adjusted?
A3: While the fixed dimension is 6.6 inches, the assembly typically allows for a calibration adjustment of ±0.5 inches (13 mm) to compensate for machine case thickness variations.
