Applications and Use Cases

This housing assembly is ideal for rotating machinery monitoring, including turbines, compressors, and pumps. It is commonly used in oil and gas, power generation, and petrochemical facilities where reliable vibration measurement is critical. The 14-inch penetration allows for deep probe installation, while the 0.5 m cable suits compact installations. For example, in a steam turbine train, this housing can be mounted to monitor shaft vibration, providing early warning of misalignment or bearing wear.

Installation and Setup

When installing the 24701-28-05-00-140-03-01, ensure the mounting thread is prepared as cast without threads, which may require custom threading on site. The fittings option includes a 3/4-14 NPT plug, a reducer to 1/2-14 NPT, and a cable seal grip with grommets for various cable diameters. Follow Bently Nevada's guidelines for proper probe gap and positioning to ensure accurate readings. Verify that the probe cable length (0.5 m) is sufficient for your routing path.

Maintenance and Reliability

Regular inspection of the housing and fittings is recommended to maintain a sealed environment. Check O-rings and grommets for wear and replace them if damaged. The stainless steel construction resists corrosion, but periodic cleaning with a mild detergent is advisable. By maintaining the housing integrity, you extend the life of the probe and reduce downtime, contributing to lower maintenance costs over time.
