🛠️ BENTLY NEVADA 1701 FIELDMONITOR 170133-050-00 PROXIMITOR SENSOR — TECHNICAL INTRODUCTION
The Bently Nevada 1701 FieldMonitor 170133-050-00 Proximitor Sensor is a high-precision, industrial-grade transducer designed for real-time monitoring of critical rotating machinery. Specifically engineered for use in turbine, compressor, and generator applications, this sensor is part of the Bently Nevada family of Proximitor systems, providing reliable proximity measurements for shaft displacement, position, and vibration. Its robust construction ensures accurate performance under harsh environmental conditions including extreme temperatures, high vibration, and electromagnetic interference.
⚙️ Product Overview
The 170133-050-00 Proximitor Sensor operates by generating an eddy-current-based measurement signal that corresponds to the distance between the sensor tip and the monitored shaft. This non-contact sensing method allows for precise measurement of shaft position without mechanical wear, ensuring long-term reliability and maintenance-free operation. The sensor integrates seamlessly with Bently Nevada 1701 FieldMonitor modules and 3500/3300 series rack systems, providing continuous feedback for condition monitoring and machinery protection systems.
Its ruggedized housing is designed for industrial environments, providing resistance to moisture, dust, and chemical exposure. Gold-plated connectors deliver reliable signal transmission, while internal circuitry ensures high immunity to electrical noise and transient events.

🛠️ Functional Characteristics
High-Precision Proximity Measurement
The sensor employs eddy-current principles to provide non-contact, high-resolution shaft position and vibration data. This ensures minimal wear, high repeatability, and superior long-term accuracy.
Rugged Industrial Design
Constructed from stainless steel and sealed against contaminants, the 170133-050-00 performs reliably under extreme temperatures, vibration, and industrial environments. Its mechanical and electrical robustness ensures signal integrity over extended periods.
Signal Reliability and Noise Immunity
The sensor’s internal electronics are optimized for low-noise signal output and high resistance to electromagnetic interference (EMI/RFI). This provides clean, accurate data to the FieldMonitor module for condition monitoring and machinery protection systems.
Versatile Mounting and Integration
Threaded and flange mounting options enable flexible installation on various machinery types. The sensor interfaces seamlessly with Bently Nevada 1701 FieldMonitor modules and 3500/3300 series racks, allowing easy integration into existing monitoring systems.
Maintenance-Free Operation
Due to its non-contact sensing design, the Proximitor Sensor requires minimal maintenance. Routine inspection is limited to verifying cleanliness of the sensor tip and ensuring secure connector engagement.
🔌 Installation & Handling Notes
- Ensure machinery and monitoring rack power are off prior to installation.
- Verify correct alignment of sensor relative to monitored shaft.
- Do not apply mechanical force directly to sensor tip.
- Inspect connectors for debris or corrosion; clean as needed.
- Periodically check cable routing to prevent strain or damage.
