With a 4.0-meter (13.1 feet) cable length, 5.0-meter (16.4 feet) system length, and panel mount design, the 330980-50-CN 3300 NSv Proximity Probe offers flexible installation options, while its compact dimension of 7.8x6x6.4cm and 0.24kg weight ensure perfect adaptability in space-constrained industrial environments.

Crafted with premium materials for durability and harsh environment resistance, the 330980-50-CN 3300 NSv Proximity Probe adopts 75 Ω coaxial cables with fluoroethylene propylene (FEP) insulation, featuring optional flexible AISI 302 stainless steel (SST) armor with/without FEP outer jacket—providing exceptional resistance to oil, moisture, corrosion, and mechanical abrasion. Equipped with multiple agency approvals, the 330980-50-CN 3300 NSv Proximity Probe meets strict global safety and industry standards, ensuring compliant deployment in diverse industrial sectors such as power generation, petrochemicals, and heavy manufacturing. Its optimized structural design, with reduced probe diameter and refined geometry, enables reliable side-view and close-clearance measurements in tight bearing housings and densely packed machinery layouts.

Applications

1. Space-Constrained Machinery Vibration Monitoring

The 330980-50-CN 3300 NSv Proximity Probe is ideally suited for vibration monitoring in machinery with limited installation space, such as tight bearing housings, densely packed equipment layouts, and small-scale rotating machinery. Its compact 7.8x6x6.4cm dimension, reduced probe diameter, and optimized geometry enable reliable side-view and close-clearance measurements without mechanical redesign—making it suitable for small centrifugal compressors, high-speed pumps, and turbine auxiliary equipment where standard probes cannot fit.

2. Shaft Position & Axial Displacement Sensing

Widely used for precise shaft position and axial displacement monitoring in critical rotating assets such as turbines, compressors, and pumps, the 330980-50-CN 3300 NSv Proximity Probe generates a linear voltage output relative to probe-to-target distance. This enables accurate detection of axial movement, thermal growth, and mechanical drift, helping prevent contact-related failures and ensuring stable equipment operation in power generation and petrochemical industries.

3. Legacy System Retrofit & Upgrade Projects

The 330980-50-CN 3300 NSv Proximity Probe is well-suited for upgrading legacy proximity measurement systems, as it supports seamless integration with existing monitoring infrastructures and accepts 3300 RAM or 3300 NSv probes and extension cables. This compatibility reduces engineering effort, shortens commissioning time, and lowers overall upgrade costs—ideal for industrial users looking to modernize systems without full infrastructure overhauls.

4. Harsh Industrial Environment Operation

Equipped with FEP-insulated coaxial cables and optional AISI 302 SST armor, the 330980-50-CN 3300 NSv Proximity Probe operates reliably in harsh environments with oil, moisture, vibration, and temperature variation. Its -50°C to +175°C operating range and corrosion-resistant construction make it suitable for power plants, petrochemical facilities, and heavy industrial machinery operating under continuous load and extreme conditions.

5. Panel-Mounted Monitoring Systems

With a 5.0-meter system length and panel mount design, the 330980-50-CN 3300 NSv Proximity Probe is optimized for panel-mounted monitoring setups in control cabinets. Its 4.0-meter cable length provides flexible wiring reach, while the panel mount design ensures secure installation—ideal for centralized monitoring systems in industrial plants where space optimization and stable signal transmission are critical.

Specifications

Competitive Advantage

1. Compact Design for Limited Installation Space

The 330980-50-CN 3300 NSv Proximity Probe features a compact 7.8x6x6.4cm dimension, reduced probe diameter, and optimized geometry, enabling accurate measurements in locations where standard proximity probes cannot be installed. Its side-view sensing capability and close-clearance design ensure reliable data collection without compromising signal quality, solving installation challenges in tight machinery spaces.

2. Stable & Linear Measurement Performance

With a standard 7.87 V/mm (200 mV/mil) scale factor, defined linear range, and supply sensitivity of less than 2 mV change per volt input, the probe delivers repeatable, low-noise output signals. Low supply sensitivity minimizes the influence of power fluctuations, ensuring consistent vibration and displacement data for condition monitoring systems—supporting accurate early fault detection.

3. Strong Compatibility for Modernization

The probe supports seamless integration with existing 3300 RAM/NSv transducer systems and legacy monitoring platforms, accepting 3300 series probes and extension cables. This compatibility reduces engineering effort, shortens commissioning time, and lowers upgrade costs—protecting users’ existing infrastructure investments while unlocking advanced performance.

4. Durable Construction for Harsh Environments

Featuring FEP-insulated 75 Ω coaxial cables and optional AISI 302 SST armor, the probe offers exceptional resistance to corrosion, oil, moisture, and mechanical abrasion. It operates stably within -50°C to +175°C, maintaining reliable performance under vibration, temperature variation, and mechanical stress—extending service life and reducing maintenance frequency.

5. Flexible Installation & Wiring

With a 5.0-meter system length, 4.0-meter cable length, and panel mount design, the probe provides flexible installation options for diverse industrial setups. The long cable length ensures flexible wiring reach, while the panel mount design enables secure installation in control cabinets—simplifying on-site deployment and reducing installation labor costs.

6. Multiple Agency Approvals for Global Compliance

Equipped with multiple agency approvals, the 330980-50-CN 3300 NSv Proximity Probe meets strict global safety and industry standards. This ensures compliant deployment across diverse regions and industries, eliminating regulatory non-compliance risks and expanding its application scope in global industrial projects.
