Bently Nevada 330780-51-CN 3300 XL 11 mm Proximitor Sensor

Description

Designed for critical machinery protection and condition monitoring, the Bently Nevada 330780-51-CN serves as a core signal conditioning component within the 3300 XL 11 mm Proximity Transducer System. This Proximitor Sensor converts the radio frequency (RF) signal generated by a non-contacting proximity probe into a proportional voltage output, enabling precise measurements of shaft vibration, position, and speed.

The 330780-51-CN is factory-configured for a 5.0-meter (16.4 feet) system length and features a robust design optimized for secure DIN-rail mounting. It accepts inputs from a single 3300 XL 11 mm proximity probe and matching extension cable, delivering reliable signal performance in heavy industrial environments like power generation and petrochemical facilities. The device is housed in a durable A380 aluminum casing and carries CN-specific agency approvals for global compatibility.

• Hydroelectric turbine guide-bearing monitoring.
• Heavy industrial pumps and gearboxes.

Technical Specifications

Installation Guidelines

• Mounting: Install the device securely on a clean, standard DIN rail inside an industrial enclosure to prevent mechanical stress.
• Power Configuration: Ensure the power supply matches the -17.5 Vdc to -26 Vdc specification. For optimal linear range performance, keep the supply voltage more negative than -23.5 Vdc.
• Cabling & Shielding: Properly shield coaxial connections and extension cables to minimize electro-magnetic interference (EMI) from high-power machinery.
• Environmental Protection: Protect the unit from direct exposure to water, excessive dust, or corrosive chemical environments beyond its rated specification.

Compliance and Certifications

• CN Approvals: Country-specific approvals for safe operation in industrial and hazardous environments.
