Bently Nevada 330780-91-00 Proximitor/Proximity Sensor Module
Manufacturer: Bently Nevada
Product Number: 330780-91-00
Category: Proximitor Sensor (3300 XL 11 mm System)
System Compatibility: 3300 XL 11 mm Proximity Transducer System
Supply Voltage: 24 VDC
Output Signal: 4-20 mA proportional to vibration/displacement
Frequency Response: 0 to 10,000 Hz
Operating Temperature: -35°C to +85°C
Product Description
The Bently Nevada 330780-91-00 is a Proximitor Sensor designed for use in the 3300 XL 11 mm Proximity Transducer System.
It provides precise, non-contact measurement of shaft vibration and position, enabling continuous monitoring and protection of critical rotating machinery such as turbines, compressors, motors, and pumps.
This model features a 10.0-meter total system length (including probe, extension cable, and proximitor), making it ideal for installations where the monitoring cabinet is located at a greater distance from the measurement point.
The 330780-91-00 is designed to meet API 670 machinery protection standards, ensuring accurate and reliable performance in demanding industrial environments.
