Quick Detail

Description

The 330903-00-05-10-01-05 is a high-precision component of the 3300 NSv Proximity Probes series, specifically engineered for environments where standard sensors cannot fit. The design of the 3300 NSv Proximity Probes system provides a versatile path for upgrading legacy instrumentation, as it is fully capable of replacing both the older 3300 RAM systems and the 3000-series or 7000-series 190 transducer systems. When transitioning from a 3300 RAM setup to the 3300 NSv Proximity Probes architecture, users can often retain existing cables and monitoring hardware by simply integrating the NSv Proximitor Sensor. However, for 3000 or 7000-series upgrades, a complete transition to 3300 NSv Proximity Probes components is required to ensure system integrity.

Technically, the 330903-00-05-10-01-05 utilizes an eddy current principle with an Average Scale Factor (ASF) of 7.87 V/mm (200 mV/mil), matching the most widely adopted industry standard for vibration monitoring. What sets the 3300 NSv Proximity Probes apart is their "Narrow Sideview" (NSv) capability. This specialized design allows the 330903-00-05-10-01-05 to operate in extremely tight spaces with significant side-view restrictions or counterbore constraints that would typically interfere with the signal of standard 5 mm or 8 mm probes. While this results in a shorter linear range of 1.5 mm (60 mils), this range still vastly exceeds that of the legacy 3000-series 190 systems. The 3300 NSv Proximity Probes are explicitly designed for small target applications, such as shafts smaller than 51 mm (2 in), where precision is non-negotiable. By deploying the 330903-00-05-10-01-05, operators ensure robust data collection in confined mechanical geometries, maintaining the high standards associated with the 3300 NSv Proximity Probes lineage.

Applications

1.Vibration Monitoring in Confined Geometries

The 330903-00-05-10-01-05 is specifically engineered for "Narrow Sideview" (NSv) scenarios where standard 8mm probes would suffer from side-view interference. In many centrifugal air compressors and refrigeration units, the counterbore or structural housing is extremely tight. These 3300 NSv Proximity Probes can accurately measure radial vibration within these restricted spaces without the signal being distorted by the surrounding metal walls of the machine.

2.High-Precision Small Shaft Measurements

A primary application for the 330903-00-05-10-01-05 is the monitoring of small-diameter shafts (typically smaller than 51 mm or 2 inches). Due to its specialized sensing field, this probe maintains high linearity even on curved surfaces that would cause standard sensors to lose accuracy. It is the ideal choice for high-speed turbo-expanders and small process gas compressors where shaft stability is critical.

3.Thermal Extreme Environments

With an operating and storage temperature range of -50°C to +175°C (-60°F to +350°F), the 330903-00-05-10-01-05 is uniquely suited for applications near hot turbine sections or in cryogenic refrigeration systems. These 3300 NSv Proximity Probes provide stable data despite severe thermal cycling, ensuring consistent monitoring of axial (thrust) position and radial movement in harsh industrial climates.

4.Phase Reference and Speed Sensing

The 330903-00-05-10-01-05 is frequently used as a Keyphasor sensor to provide phase reference signals. Its ability to trigger off small notches or keys—combined with its 1.6 mm linear range and a recommended 1.0 mm (40 mils) gap setting—allows it to capture precise timing data. This is essential for diagnostic tools that calculate 1X vibration vectors and for tachometer systems monitoring zero-speed or overspeed conditions.

Specifications

Competitive Advantage

1.Optimized for Restricted Mounting Spaces

The most significant edge of the 330903-00-05-10-01-05 is its specialized "Narrow Sideview" (NSv) geometry. While standard 5 mm or 8 mm probes suffer from signal interference when placed in tight counterbores, these 3300 NSv Proximity Probes are designed to ignore surrounding sidewalls. With a 0-inch unthreaded length and a compact 50 mm case, this model can be installed in flush or recessed positions that are physically impossible for competing sensors to navigate.

2.Exceptional Thermal Stability and Resilience

The 330903-00-05-10-01-05 offers a superior operating temperature range from -50°C to +175°C. This high-temperature capability allows the 3300 NSv Proximity Probes to be deployed in the hottest sections of industrial compressors where standard probes might experience insulation breakdown or signal drift. Its low supply sensitivity (less than 2 mV change per volt) ensures that even under fluctuating power conditions, the vibration data remains accurate and stable.

3.Advanced ClickLoc Connectivity with Protection

A major mechanical advantage is the Miniature coaxial ClickLoc connector paired with a connector protector. This system prevents the common issue of connectors vibrating loose or being damaged by environmental contaminants. This "lock-and-protect" design ensures that the 3300 NSv Proximity Probes maintain a low 45 Ω output resistance and consistent signal integrity throughout the 1.0-meter total length, significantly reducing the risk of intermittent data loss.

4.Precision Performance on Small Targets

The 330903-00-05-10-01-05 provides a distinct advantage for monitoring shafts smaller than 51 mm. Unlike general-purpose sensors that experience "average out" signals on highly curved surfaces, these 3300 NSv Proximity Probes maintain a highly linear 1.6 mm range. This precision allows for a more aggressive 1.0 mm (40 mils) gap setting, providing higher resolution for detecting early-stage bearing wear or shaft instability.
