Bently Nevada 31000-28-10-00-114-03-02 Proximity Probe Housing

Technical Overview

The Bently Nevada 31000-28-10-00-114-03-02 is a rigid proximity probe housing designed for the external mounting of 3300 NSv series proximity probes. Its primary function is to provide a mechanically robust and environmentally sealed enclosure that ensures precise, stable positioning of the probe relative to a machine shaft. Constructed from 316 Stainless Steel, this housing offers superior corrosion resistance in aggressive industrial settings. The unit includes a 2.8-inch standoff adapter, which provides thermal isolation and accommodates physical obstructions. By maintaining a fixed probe gap, the housing is critical for acquiring accurate vibration, thrust position, and rotor speed data. This data is transmitted to a monitoring system, such as the Bently Nevada 3500 Machinery Protection System, for continuous asset condition analysis and automated machine shutdown to prevent catastrophic failure. The housing’s design facilitates secure installation and reliable long-term operation on critical rotating machinery.

Operational Capabilities

Engineered for high-demand applications, this 316 stainless steel housing is ideally suited for the harsh operating conditions found in the Oil & Gas and Power Generation industries. It provides essential protection for proximity sensors monitoring critical assets such as steam turbines, gas turbines, centrifugal compressors, and large pump systems. Its robust construction ensures measurement integrity despite exposure to corrosive agents, high humidity, and wide temperature fluctuations common in these environments.

Technical FAQ

Is this housing assembly compatible with the 3300 XL 8mm probe series?

No, this housing is not compatible with the 3300 XL 8mm probe series. The 31000 model housing is specifically designed to accommodate the physical dimensions and mounting specifications of the Bently Nevada 3300 NSv Proximity Probe. The part number option “-10” explicitly designates its configuration for a 3300 NSv probe with a 1.0-meter system length. Attempting to install a different probe series will result in improper fitment, incorrect gap positioning, and unreliable measurement data.

What is the purpose of the 2.8-inch standoff adapter included with this housing?

The 2.8-inch standoff adapter serves two primary functions. First, it provides thermal isolation by increasing the distance between the hot machine casing and the probe body, protecting the probe’s electronics from excessive temperatures. Second, it provides mechanical clearance, allowing the housing to be mounted in locations where obstructions might otherwise prevent direct installation. This ensures the probe tip can be correctly positioned at the required distance from the shaft surface, even with complex machine geometries.
