Датчик Bently Nevada 330980-51-CN 3300 XL NSv Proximitor

Description

The 330980-51-CN is a high-performance proximity sensor designed for use within the 3300 XL NSv Proximity Transducer System. This eddy current sensor provides precise non-contacting vibration and position measurements on machinery with tight installation constraints or small target areas, such as centrifugal air compressors, refrigeration compressors, and process gas compressors. By operating with an Average Scale Factor of 7.87 V/mm (200 mV/mil), the 330980-51-CN delivers highly accurate radial vibration, radial position, axial position, tachometer, and phase reference (Keyphasor) signals from fluid-filmed bearing machines.

Engineered with a compact and thin form factor, this Proximitor Sensor is specifically configured for high-density 35 mm DIN-rail mounting, allowing industrial operators to optimize enclosure space. The device boasts enhanced immunity to radio frequency interference (RFI) and electromagnetic interference (EMI), ensuring signal integrity without needing specialized mounting hardware or isolated enclosures.

Features

• Offers 1.5 mm (60 mils) of linear range, optimizing side-view and small-target measurement capability.
• Equipped with integrated SpringLoc terminal strips that enable swift, reliable field wiring connections without requiring specialized installation tools.
• Provides exceptional RFI/EMI immunity to prevent high-frequency radio signals from degrading transducer performance.
• Designed to directly replace legacy 3300 RAM Transducer Systems and 3000-series or 7000-series 190 Transducer Systems.
• Employs internal protection circuits against electrostatic discharge on terminal and connector surfaces.

Applications

• Centrifugal air compressors 
• Refrigeration compressors 
• Process gas compressors 
• Fluid-filmed bearing machinery with small shafts or reduced side-view spacing 
• Radial vibration and axial (thrust) position monitoring 
• Tachometer, zero speed, and Keyphasor phase reference signal tracking

Technical Specifications

Installation Guidelines

• Mounting Configuration: Designed to fit securely onto standard 35 mm DIN rails via its specialized high-density integrated base mount. Ensure the rail is properly secured and grounded to the enclosure grid.
• Field Wiring: Supports wire cross-sections from 0.2 to 1.5 mm2 (16 to 24 AWG), or 0.25 to 0.75 mm2 (18 to 23 AWG) when utilizing wire ferrules. A three-conductor shielded triad cable is recommended for connections between the sensor and the monitoring rack.
• Maximum Distance: The maximum allowable cable distance between the Proximitor Sensor and the monitoring system is 305 meters (1000 feet).
• ESD Precautions: Utilize an ESD wrist strap and follow safety handling procedures during terminal wiring to shield internal circuitry from electrostatic discharge.
