BENTLY 330180-91-CN
Product Introduction
The Bently Nevada 330180-91-CN is a specialized proximity transducer system designed specifically for the Chinese industrial market. As part of the globally recognized 3300 XL series, this variant maintains the same precision measurement capabilities while incorporating local compliance features required for Chinese power generation and heavy industries.
Engineered for critical machinery protection, the 330180-91-CN provides non-contact monitoring of shaft vibration, position, and eccentricity in turbines, compressors, and other high-value rotating assets. Its GB/T certification ensures full compliance with Chinese regulatory requirements while delivering the same reliability as the international version.
Core Advantages and Technical Highlights
Precision measurement performance:
The Bently Nevada 330180-91-CN delivers ±1% linearity across its full 0.08-1.27mm measurement range, with 7.87 V/mm sensitivity for detecting minute displacement changes. The 10kHz frequency response captures both slow shaft movements and rapid vibration events.
Chinese market adaptation:
This model features custom cable lengths tailored to typical Chinese plant configurations and GB/T markings for local compliance. The design maintains compatibility with both international and domestic monitoring systems while meeting Chinese electrical and safety standards.
Robust industrial construction:
The 316 stainless steel housing provides exceptional corrosion resistance in China’s diverse industrial environments – from coastal power plants to inland refineries. The -40°C to +120°C operating range ensures reliability across all Chinese climate zones.
Enhanced reliability features:
Hermetically sealed electronics prevent moisture ingress in high-humidity regions. The military-grade connector maintains signal integrity despite vibration common in Chinese industrial settings. EMI/RFI shielding ensures stable operation near high-power equipment.
Typical Application Scenarios
Chinese thermal power plants:
Monitoring turbine-generator shafts in coal-fired plants, the 330180-91-CN detects misalignment and bearing wear while withstanding coal dust and ash exposure. Its GB certification simplifies regulatory compliance.
Petrochemical complexes:
In SINOPEC and CNOOC facilities, the transducer provides compressor shaft positioning data. The stainless steel construction resists sulfur compounds and acidic atmospheres common in Chinese refineries.
Steel mill applications:
The Bently Nevada 330180-91-CN monitors rolling mill drives in Baowu and other major steel groups, withstanding the extreme vibration and temperature fluctuations of continuous casting operations.
Hydroelectric projects:
At Three Gorges and other mega-dams, the transducer tracks generator shaft runout, with custom cable lengths accommodating massive turbine geometries.
