📘 Bently Nevada 1701 FieldMonitor 170133-090-00 Proximitor Sensor — Product Overview
The Bently Nevada 1701 FieldMonitor 170133-090-00 Proximitor Sensor is a high-precision displacement sensor designed for critical machinery monitoring applications. Specifically developed for rotating equipment, this sensor accurately measures shaft vibration, position, and motion characteristics in real-time, providing reliable input to the 3300 Series monitoring systems. The 1701 Proximitor Sensor is widely deployed in power plants, petrochemical facilities, compressors, turbines, and other industrial machinery where precise shaft monitoring is essential to prevent mechanical failures.
The sensor operates on eddy-current proximity principles, converting minute variations in the distance between the probe and the target shaft into a voltage signal. This signal is then transmitted to associated monitoring modules, where it is processed for vibration analysis, alarm generation, and condition monitoring. Its rugged construction ensures durability and stable performance under extreme industrial environments, including high temperatures, humidity, and vibration exposure.
