Bently Nevada 330780-90-CN 3300 XL Proximitor Sensor

Description

For industrial machinery vibration and displacement monitoring, the 330780-90-CN serves as a critical signal conditioning module within the Bently Nevada 3300 XL 11 mm Proximity Transducer System. This Proximitor sensor accepts high-frequency radio frequency (RF) signals from an 11 mm proximity probe, converting the physical gap between the probe tip and the observed conductive target into a linear, dynamic voltage output.

Operating within the established 3300 XL framework, this device delivers high noise immunity and remains stable across varying ambient conditions. The hardware is calibrated for a 9.0-meter system length, requiring matching probe and extension cable configurations to maintain scale factor accuracy. With the CN agency approval configuration, this module meets country-specific regulatory compliance standards for installation in hazardous industrial environments.

Features

• Engineered for compatibility with Bently Nevada 3300 XL 11 mm proximity probe systems.
• Factory-calibrated for a total physical system length of 9.0 meters (29.5 feet).
• Delivers a continuous linear voltage output proportional to static and dynamic displacement.
• Supplied with the CN agency option to meet localized hazardous location certifications.
• Designed with durable construction for high resistance to electromagnetic interference (EMI) and radio frequency interference (RFI).
• Supports DIN rail mounting and panel installation profiles.

Applications

• Steam, gas, and hydro turbine shaft vibration monitoring.
• Radial vibration and axial thrust position tracking in large centrifugal compressors.
• Critical industrial pump, blower, and fan monitoring systems.
• API 670 compliant machinery protection and monitoring configurations.

Installation Guidelines

• Verify that the combined length of the proximity probe and extension cable matches the 9.0-meter calibration of the 330780-90-CN Proximitor sensor.
• Mount the Proximitor sensor inside a weather-proof, protective enclosure to shield electrical terminals from environmental contaminants.
• Use physical connector protectors on coaxial connections to prevent moisture ingress and signal degradation.
• Isolate the Proximitor DIN-rail mounting base from local structural ground loops to maintain signal fidelity.
