Introduction to the 21000-16-10-00-040-03-02

When machinery uptime is critical, the 21000-16-10-00-040-03-02 from Bently Nevada delivers a robust solution for proximity probe mounting. This housing assembly is engineered for harsh industrial environments, offering explosion-proof ratings and CSA Type 4 enclosure certification. By providing a secure, sealed housing for a 3300 XL 8 mm probe, it ensures accurate vibration and position measurements that help prevent costly unplanned downtime.

Key Features and Technical Specifications

The 21000-16-10-00-040-03-02 is built around a 21000 aluminum body with a 304 stainless steel sleeve, offering corrosion resistance and durability. It includes a 1.0 m (39 in) probe cable and a 4 in probe penetration depth. The assembly comes with one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and a cable seal grip with grommets for cable sizes from 1/8 to 3/8 inches. The mounting thread is 3/4-14 NPT. This configuration supports a maximum (C) + (D) dimension of 32.9 in (83.5 cm) with visible probe P/N and S/N. The typical weight is 1.1 kg (2.4 lb) without fittings. These specs directly reduce installation time and material costs, as the included fittings eliminate the need for separate purchases.

Applications and Use Cases

In rotating machinery monitoring, the 21000-16-10-00-040-03-02 excels for compressors, turbines, and pumps. Its CSA explosion-proof rating makes it suitable for hazardous areas where safety and reliability are paramount. By using this housing, engineers can achieve consistent probe positioning, which improves data accuracy and reduces false alarms. This leads to lower maintenance costs and extended equipment life.

Installation and Setup

Mounting the 21000-16-10-00-040-03-02 requires selecting the correct standoff adapter or using the direct 3/4-14 NPT thread. The included cable seal grip accommodates various cable diameters, simplifying conduit connections. Ensure the probe sleeve length matches the required gap for your machine. Always follow Bently Nevada’s guidelines for torque and alignment to maximize measurement repeatability and avoid premature wear.

Maintenance and Reliability

Periodic inspection of the housing seals and cable connections helps maintain the explosion-proof integrity of the 21000-16-10-00-040-03-02.
