Technical Specifications

Installation & Maintenance

1. Standoff Mounting: The 1.5-inch standoff adapter provides necessary mechanical clearance for the 21000-16-10-15-114-03-02. Ensure the mounting thread (3/4-14 NPT) is properly sealed to maintain the explosion-proof rating.

2. Gap Calibration: Using a multimeter, set the proximity probe gap to the center of the linear range (standard -10.0 Vdc). This ensures the most accurate vibration data for your Machinery Protection System (MPS).

3. Fittings and Seals: The 03 fittings package includes grommets for various cable sizes (1/8" to 3/8"). Choose the correct grommet to ensure the cable seal grip is airtight and compliant with hazardous area requirements.

Engineering Advantages

The Bently Nevada 21000 series housing offers unmatched environmental protection. Its aluminum body is epoxy-coated for durability, while the 304 stainless steel sleeve resists corrosion from harsh process fluids. This 11.4-inch penetration model is ideal for medium-to-large machinery casings, providing the structural support needed to prevent sensor vibration while maintaining the CSA Type 4 enclosure rating for safe operation in Class 1, Division 1 and 2 areas.

Technical FAQs

Q1: What is the maximum operating temperature?
A1: The housing is rated T4 for environments between -50°C to +80°C, and T5 for -50°C to +40°C.

Q2: Is the probe included in this assembly?
A2: Yes, the code "16" indicates that a 3300 XL 8mm proximity probe is pre-installed in the housing.

Q3: Can I adjust the depth after installation?
A3: Yes, the 21000-16-10-15-114-03-02 offers an adjustment range of ±13 mm (±0.5 in) to fine-tune the probe gap.
