Industry Applications

Engineers use the 21000-16-05-15-114-03-02 in applications such as turbine monitoring, compressor protection, and pump vibration analysis. It is suitable for hazardous areas with CSA explosion-proof certification. The housing meets CSA Type 4 enclosure standards and complies with API 670 for externally mounted probes. This makes it a trusted choice for oil and gas, power generation, and heavy industrial plants.

Installation and Setup

Mount the assembly using the 3/4-14 NPT thread. For probe penetration lengths between 1.0 and 2.0 inches, counter boring the machine case may reduce side view effects. If the total probe penetration (C plus D) exceeds 300 mm (12 in), add sleeve support near the probe to prevent resonance. The adjustment range for option D is 13 mm (± 0.5 in). Use the supplied fittings to secure conduit connections.

Maintenance and Reliability

Regular inspection of the housing and probe cable helps maintain accuracy. Check O-rings and thread seals during routine maintenance. The aluminum and stainless steel construction resists corrosion in harsh environments. Following these practices extends service life and reduces unplanned downtime, supporting cost-effective operations.

Compatibility and Integration

The 21000-16-05-15-114-03-02 works with Bently Nevada monitoring systems and other compatible vibration monitoring equipment. It is designed for use with 3300 XL series probes. The housing is available with CSA approvals for hazardous areas, making it suitable for integrated safety systems. For specific system compatibility, refer to the official Bently Nevada documentation.
