Product Summary
The Bently Nevada 170FNT11000 Proximitor Sensor delivers precise shaft vibration and position measurements for critical rotating machinery. This robust sensor ensures reliable performance in harsh industrial environments, supporting predictive maintenance strategies and minimizing unplanned downtime.
Core Technical Specifications & Parameters
The 170FNT11000 Proximitor Sensor is engineered for high-accuracy displacement monitoring. It operates with a standard -24 Vdc power supply and provides a direct output voltage proportional to the gap between the probe tip and the target surface. The sensor system offers a linear measurement range of 2.0 mm (80 mils) with a sensitivity of 7.87 V/mm (200 mV/mil). This configuration ensures a resolution of less than 0.1 micrometers for detecting minute shaft movements. The frequency response extends from 0 to 10 kHz, covering both static position and dynamic vibration signals. The operating temperature range spans from -35°C to +120°C for the probe and extension cable, while the Proximitor driver functions reliably from -35°C to +85°C. The system demonstrates excellent noise immunity with a signal-to-noise ratio exceeding 30 dB. The 170FNT11000 model specifically includes a 5-meter system cable length for flexible installation.
Professional Installation & Wiring Guidelines
Begin by mounting the Proximitor driver in a suitable enclosure away from excessive heat and moisture. Ensure the probe tip is clean and free from debris before threading it into the mounting bracket. Tighten the probe to the specified torque of 20 Nm to prevent movement during operation. Connect the extension cable between the probe and the driver using the provided coaxial connectors. Wire the driver power supply to a -24 Vdc source, observing correct polarity to avoid damage. The output signal connects to a monitoring system with an input impedance of at least 10 kOhms. Verify the total cable length does not exceed 305 meters to maintain signal integrity. Perform a static calibration by adjusting the gap voltage to -10 Vdc when the target is at the midpoint of the linear range.
