Bently Nevada 330180-X1-00 MOD:145004-128 3300 XL Proximitor Sensor

Description

330180-X1-00 MOD:145004-128 is a 3300 XL Proximitor Sensor configured to support specialized machinery monitoring requirements. This unit acts as the signal conditioning interface in a 3300 XL 8 mm proximity transducer system, converting the eddy-current probe signal into a linear 4 to 20 mA proportional output for critical vibration and axial position monitoring applications. The sensor is designed for high-precision, non-contact measurement of rotor shaft displacement, providing critical diagnostic data for rotating machinery such as turbines, compressors, and large motors.

The Proximitor sensor is optimized for use within the 3300 XL series monitoring chains, ensuring electrical and physical compatibility with standard 3300 XL probes and extension cables. This configuration includes specific modifications (MOD:145004) to meet unique installation or operational criteria. The system delivers a stable 200 mV/mil scale factor and is engineered to maintain signal integrity over field wiring distances up to 305 meters.

Technical Specifications

Installation Guidelines

• Ensure the total system length (Probe + Extension Cable + Proximitor) matches the calibrated Proximitor sensor length for accurate measurement.
• Mount the Proximitor sensor in a protected, dry location, ideally using the Bently Nevada DIN-mount or panel-mount hardware.
• Use 3-conductor shielded twisted-pair cable for field wiring to minimize EMI/RFI interference.
• Maintain a minimum cable bend radius of 25.4 mm (1.0 in) to prevent coaxial cable damage.
• Ensure the probe gap is set to the recommended voltage (typically -9 Vdc) for radial vibration monitoring.
