Bently Nevada Model 330100 Pn.102046-50 Custom Proximitor

Description

The Bently Nevada 330100 (P/N 102046-50) is a Custom Proximitor designed for non-contact shaft vibration and axial position measurement in rotating machinery monitoring systems. The unit conditions radio frequency (RF) signals sent to a paired eddy current proximity probe to generate a DC voltage output proportional to static gap distance and an AC voltage output proportional to dynamic shaft vibration. Designed to operate with an 8 mm probe tip diameter and a 5-meter total system cable length, the device conditions analog transducer signals calibrated specifically for AISI 4140 target material at a scale factor of 200 mV/mil.

Features

• Pre-calibrated for AISI 4140 target material with a scale factor of 200 mV/mil
• Compatible with 8 mm probe tip diameter proximity sensors
• Matched for 5-meter total system cable length configuration
• Direct terminal connections for power, signal ground, and output lines
• CSA certified for hazardous location installations

Applications

• Industrial steam turbine and gas turbine shaft vibration monitoring
• Centrifugal compressor shaft position and radial displacement tracking
• Boiler feed pump shaft displacement and thrust position measurement
• High-speed industrial gearbox proximity transducer signal processing

Installation Guidelines

• Ensure power supply wiring matches the specified -24 Vdc operating voltage.
• Install in accordance with installation drawing DWG CA22000 for hazardous location compliance.
• Maintain clean, tight connections on terminal block terminals labeled OUT, COM, and Vt.
• Ensure the physical cable length matches the 5-meter system rating for optimal calibration accuracy.
• Verify target material compatibility with AISI 4140 to prevent scale factor error.
