BENTLY 87199-01

Product introduction

The BENTLY NEVADA 87199-01 is a high-performance eddy current proximity sensor system, designed to measure shaft position, vibration, and speed in rotating machinery. As a core component of machinery protection systems, it provides precise, non-contact measurements critical for monitoring equipment health in industries such as power generation, oil and gas, and manufacturing.

This sensor system operates on the eddy current principle, where a high-frequency alternating current in the sensor coil creates a magnetic field that induces currents in the target (typically a rotating shaft). Changes in the gap between the sensor and the target alter the impedance of the coil, producing a voltage output proportional to the gap. This output is conditioned by modules like the 3500/42 176449-02 and analyzed by software such as 170180-01-00, enabling real-time monitoring and diagnostics of machinery behavior.

The 87199-01 is renowned for its ruggedness and reliability in harsh industrial environments, making it ideal for applications where extreme temperatures, vibration, or contamination are present. Its compatibility with 3500 series modules and configuration software ensures seamless integration into comprehensive protection systems, providing actionable data to prevent unplanned downtime.

Core advantages and technical highlights

Non-contact measurement: The 87199-01 uses eddy current technology to measure shaft position without physical contact, eliminating wear and tear on both the sensor and the machinery. This non-intrusive design is critical for high-speed rotating equipment (e.g., turbines, compressors), where even minimal friction could cause damage or affect performance.

Wide operating range: With a temperature tolerance of -20°C to +177°C for the sensor and -54°C to +204°C for the cable, the system thrives in extreme environments such as turbine exhaust sections or high-temperature pumps. Its frequency response (0 Hz to 10 kHz) captures both static position (e.g., shaft axial movement) and dynamic vibration (e.g., bearing instability), providing a comprehensive view of machinery health.

High accuracy and stability: The sensor delivers ±1% full-scale accuracy, ensuring precise measurements of shaft runout, vibration amplitude, and thrust position. This level of precision is essential for early detection of issues like misalignment or bearing degradation, which can be analyzed in detail using 170180-01-00 software to predict maintenance needs.

Seamless integration with 3500 series: The 87199-01’s -2 V to +2 V output directly interfaces with the 3500/42 176449-02 signal conditioner and 3500/33 149986-01 vibration monitor, which convert and amplify the signal for further processing. The 170180-01-00 software then visualizes this data, allowing users to configure alarm thresholds, log trends, and perform spectral analysis to identify specific machinery faults.

Typical application scenarios

In a gas turbine power plant, 87199-01 sensors are installed at bearing housings to monitor shaft vibration and axial position. The sensor outputs are fed to 3500/33 149986-01 modules, which filter and amplify the signals before transmission to the 3500/05 rack interface. Operators use 170180-01-00 software to track vibration trends, and if amplitudes exceed predefined thresholds, the 3500/60 163179-01 relay module triggers a shutdown—preventing catastrophic failure.

Within an oil refinery’s centrifugal compressor train, the 87199-01 measures shaft radial vibration and speed. The sensor’s high-temperature tolerance ensures reliable operation near hot process fluids, while its 10 kHz frequency response captures rapid vibration spikes caused by rotor imbalance. The 3500/42 176449-02 conditions the signal, and 170180-01-00 software analyzes spectral data to distinguish between imbalance, misalignment, and bearing defects—enabling targeted maintenance.

In a paper mill’s motor-driven roll system, the sensor monitors shaft position to detect misalignment between the motor and roll. The 87199-01’s non-contact design avoids interference with the high-speed roll, while its Teflon cable resists contamination from paper dust and moisture. Data from the sensor is processed by the 3500/42 176449-02 and displayed on the 3500/50 133388-02 module, with 170180-01-00 generating reports to track alignment over time and schedule adjustments during planned outages.

Relationship with 170180-01-00 and other modules

The 87199-01 is a foundational sensor that feeds critical data into the 3500 series ecosystem, working in tandem with 170180-01-00 software and other modules:

With 170180-01-00: The software configures measurement parameters for the 87199-01 (e.g., scaling, alarm thresholds) via the 3500/42 176449-02 or 3500/33 149986-01. It logs vibration and position data from the sensor, enabling trend analysis, FFT spectral plots, and fault diagnostics. Engineers use 170180-01-00 to correlate 87199-01 readings with other parameters (e.g., temperature from thermocouples) to identify root causes of machinery issues.

With 3500/42 176449-02: The signal conditioner converts the 87199-01’s raw -2 V to +2 V output into standardized 4-20 mA signals for transmission to PLCs or DCS systems. It also filters noise from the sensor signal, ensuring clean data for both local display on the 3500/50 133388-02 and remote analysis via 170180-01-00.

With 3500/33 149986-01: The vibration monitor processes the 87199-01’s output to calculate peak-to-peak vibration amplitudes and detect transient events (e.g., rubs). It sends alarm signals to the 3500/60 163179-01 relay module when thresholds are exceeded, while raw data is forwarded to 170180-01-00 for detailed post-event analysis.

With 3500/05: The rack interface module aggregates data from the 87199-01 (via conditioning modules) and distributes it to both local displays and remote systems, ensuring that 170180-01-00 has real-time access to sensor measurements for monitoring and configuration.

Installation, calibration and maintenance instructions

Installation preparation: Mount the 87199-01 sensor perpendicular to the target shaft surface, ensuring a gap of 1.27 mm (0.050 inches) for optimal performance. Use 316 stainless steel mounting hardware to resist corrosion. Route the Teflon cable away from high-voltage lines and heat sources, securing it with cable ties to prevent vibration-induced damage.

Wiring and connection: Connect the sensor cable to the 3500/42 176449-02 or 3500/33 149986-01 module, following polarity markings. For long cable runs, use twisted-pair shielding and ground the cable at the sensor end only to avoid ground loops. Verify continuity with a multimeter before powering on the system.

Calibration: Use 170180-01-00 software to calibrate the 87199-01 via the connected 3500 series module. Apply known gap values (using a feeler gauge) and adjust the module’s scaling to ensure the output matches the actual gap. Perform a linearity check across the full measurement range to confirm accuracy within ±1% of full scale.

Maintenance suggestions: Inspect the sensor tip quarterly for fouling or damage—clean with a soft cloth and solvent if necessary. Check cable integrity for cuts or abrasions, especially in high-vibration areas. Re-calibrate annually using 170180-01-00 to account for drift, and verify alignment if machinery vibration patterns change unexpectedly. Replace the sensor if output becomes unstable or non-linear, as this may indicate coil degradation.
