Bently 330780-51-00 Proximity Transmitter

Technical Specifications

• Input Signal: Compatible with 3300 XL series eddy current probes (e.g., 8 mm, 11 mm, 25 mm, 50 mm probe diameters).
• Output Signal: Standardized voltage or current signal (e.g., -10 V to +10 V DC, 4-20 mA).
• Frequency Response: 0 Hz to 8 kHz (adjustable based on probe and application requirements).
• Sensitivity: Typically 7.87 mV/μm (200 mV/mil) for 11 mm probes; varies with probe type.
• Supply Voltage: 24 V DC (±10%).
• Operating Temperature: -35°C to +65°C (standard); extended range options available up to +260°C.
• Enclosure: Compact design with options for DIN rail or panel mounting.
• Electrical Connections: ClickLoc™ shielded connectors for secure, tool-free installation.
• Certifications: CE compliant, meets API 670 and other international standards for mechanical protection systems.

Functional Features

• Signal Conditioning: Amplifies, demodulates, and filters weak probe signals to extract accurate displacement or vibration data.
• High Sensitivity: Enables precise measurement of micro-level mechanical movements (e.g., 0.1 μm resolution).
• Anti-Interference Design: Advanced RFI/EMI shielding ensures stable performance in harsh electromagnetic environments.
• Flexible Installation: Supports both DIN rail and panel mounting, with electrically insulated bases eliminating the need for separate insulation plates.
• Easy Maintenance: Spring-loaded terminal blocks allow quick and secure wiring without special tools.
• Compatibility: Seamlessly integrates with Bently Nevada’s 3500 series monitoring modules (e.g., 3500/42 vibration monitor, 3500/20 axial displacement monitor).
