Its robust 24V DC architecture and extended temperature tolerance ensure consistent performance where other sensors fail, making it the preferred choice for engineers who demand measurement integrity in harsh operating conditions.

Core Features & Benefits

→ Micron-Level Measurement Precision
7.87 mV/µm (200 mV/mil) scale factor captures subtle vibration changes that indicate bearing wear, misalignment, or imbalance before catastrophic failure occurs. This sensitivity enables detection of anomalies at 0.1 mil displacement levels.

→ Extended Installation Flexibility
5.0-meter (16.4 ft) system length accommodates challenging mounting geometries in crowded machinery spaces, reducing installation complexity and cable routing constraints in retrofit applications.

→ Universal Probe Compatibility
Engineered for seamless operation with 3300 Series 5mm and 8mm proximity probes, protecting existing infrastructure investments while enabling standardized spare parts inventory across multiple sites.

→ Extreme Environment Resilience
Operates reliably from -30°C to +70°C (-22°F to +158°F), withstanding temperature swings in outdoor installations, desert climates, and arctic conditions without recalibration or performance degradation.

→ Industry Standards Compliance
Fully conforms to API 670 machinery protection system requirements and ISO 20816 vibration severity standards, ensuring regulatory compliance for critical equipment in oil & gas, power generation, and marine sectors.

✓ Plug-and-Play Integration
Standard 24V DC power supply matches existing DCS and PLC infrastructure, eliminating custom power conditioning requirements and accelerating commissioning timelines.

Typical Application Scenarios

Power Generation Turbomachinery
In combined-cycle power plants, the 170133-050-00 monitors steam turbine shaft displacement and generator bearing vibration. By detecting rotor eccentricity trends during startup transients, operators prevent blade rubs that cause million-dollar forced outages. The sensor's high-temperature capability handles turbine pedestal environments where ambient temperatures exceed 60°C.

Upstream Oil & Gas Compression
Natural gas processing facilities deploy this Proximitor on centrifugal compressor trains operating at 10,000+ RPM. Real-time thrust position monitoring prevents catastrophic bearing failures in unmanned offshore platforms, where a single unplanned shutdown costs $500K+ per day in lost production.

Petrochemical Process Pumps
Refineries utilize the 170133-050-00 for continuous monitoring of high-pressure feed pumps handling corrosive fluids. Early detection of cavitation-induced vibration enables scheduled maintenance during planned turnarounds, avoiding emergency repairs that disrupt production schedules.

Marine Propulsion Systems
Shipboard installations benefit from the sensor's vibration resistance and extended cable length, which accommodates engine room layouts with remote monitoring panels. Compliance with maritime classification society requirements ensures vessel certification for international operations.

Industrial Fan & Blower Arrays
Cement plants and steel mills apply this technology to induced draft fans and forced draft blowers, where bearing failures create safety hazards and production bottlenecks. The 170133-050-00's dust-tolerant design maintains accuracy in particulate-laden atmospheres.

Technical Parameters & Selection Guide

Selection Criteria: Choose the 170133-050-00 when your application requires 5-meter probe-to-monitor separation with standard 200 mV/mil output. For longer cable runs, consider alternative system lengths. Verify probe compatibility with existing 3300 Series infrastructure before ordering. Consult factory documentation for hazardous area certifications if deploying in Zone 1/Division 1 environments.

Frequently Asked Questions

What proximity probe models are compatible with the 170133-050-00 Proximitor?
This sensor works with all Bently Nevada 3300 Series proximity probes in 5mm and 8mm diameters, including standard, high-temperature, and NSv (non-standard voltage) variants. Probe selection depends on target material, operating temperature, and required measurement range.

Can this sensor monitor both radial vibration and axial position simultaneously?
A single 170133-050-00 unit monitors one measurement point (either radial or axial). Complete turbomachinery monitoring typically requires multiple sensors—two for radial vibration (X-Y plane) and one for thrust position. Consult API 670 guidelines for minimum sensor quantities per machine type.

How does the 5-meter system length affect measurement accuracy?
The 170133-050-00 is factory-calibrated as a complete system (probe + cable + Proximitor), ensuring accuracy across the full 5-meter length. Extending or shortening cables post-calibration will alter the scale factor and require recalibration to maintain specified accuracy.

Is this sensor suitable for hazardous area installations?
The standard 170133-050-00 is designed for general industrial use. For Zone 1/Division 1 hazardous locations, specify intrinsically safe (IS) barrier configurations or explosion-proof housings when ordering. Consult Baker Hughes for ATEX/IECEx certification documentation.

What output signal does the sensor provide to monitoring systems?
The Proximitor delivers a buffered DC voltage output proportional to probe gap (typically -2V to -18V for 0-80 mil range). This signal feeds directly into vibration monitors, protection systems, or data acquisition modules. Optional 4-20mA converters available for PLC integration.

How often does the 170133-050-00 require recalibration?
Under normal operating conditions, annual verification is recommended. Recalibration becomes necessary after cable replacement, probe changes, or if trending data shows unexplained baseline shifts. Factory recalibration services available with 5-7 day turnaround.
