Bently 330180-090-00
Technical Specifications
- Product Series: 3300 XL 8mm Proximitor Sensor
- Part Number: 330180-090-00
- System Length: 9.0 meters (29.5 feet)
- Mounting Style: Panel mount
- Agency Approval: Not required (standard version)
- Power Supply: -17.5 to -26 Vdc (without safety barrier); -23 to -26 Vdc (with safety barrier)
- Maximum Current: 12 mA
- Output: Voltage or current signal with output short-circuit protection
- Output Impedance: 50Ω
Functional Features
- Signal Conditioning: Receives the high-frequency signal from the 3300 XL 8mm proximity probe and extension cable, demodulates the impedance change, and converts it into a linear DC voltage output proportional to the gap distance.
- Dual Measurement Capability: The output voltage contains both a DC component (for static displacement/position measurement) and an AC component (for dynamic vibration measurement), enabling simultaneous monitoring of shaft position and vibration.
- Extended System Length: The 9.0 meter system length accommodates installations where the Proximitor must be mounted at a greater distance from the probe, providing greater routing flexibility in complex machinery layouts.
- Strong Anti-Interference: Improved RFI/EMI immunity meets European CE electromagnetic compatibility standards, allowing installation in fiberglass enclosures without being affected by nearby radio frequency signals. No special shielded conduits or metal enclosures are required.
- Panel Mount Design: Traditional four-hole panel mounting configuration, compatible with existing 3300 series mounting hole patterns. The mounting base provides electrical insulation, eliminating the need for a separate isolation plate.
- Full Interchangeability: All 3300 XL 8mm Proximitor sensors, probes, and extension cables are fully interchangeable without the need for individual matching or bench calibration.
- Backward Compatibility: Compatible with other non-XL 3300 series 5mm and 8mm sensor system components.
- Extended Temperature Range: Suitable for extended temperature range applications when paired with appropriate high-temperature probes and cables.
Application Scenarios
Widely used in power generation, petrochemical, refining, steel, and chemical industries for vibration monitoring of large and medium-sized rotating machinery. Typical applications include steam turbines, gas turbines, centrifugal compressors, pumps, fans, motors, generators, gearboxes, and water turbines. The system measures shaft radial vibration, axial displacement, keyphasor, rotational speed, and differential expansion in oil-film bearing machines. The 9.0 meter system length is particularly suitable for compression systems, speed measurement applications, and fluid-film bearing machines where the Proximitor must be located far from the probe mounting point due to space constraints or environmental conditions near the machinery.
Performance Parameters
- Linear Range: 2 mm (80 mils), starting from approximately 0.25 mm (10 mils) from the probe face
- Sensitivity: 7.87 V/mm (200 mV/mil)
- Frequency Response: 0 to 10 kHz (typical +0 to -3 dB)
- Linear Deviation: Less than ±0.31 mm (±12 mils)
- Recommended Gap Setting: 1.27 mm
- Minimum Target Size: 15.2 mm diameter
- Minimum Shaft Diameter: 76.2 mm (3 inches)
- Proximitor Operating Temperature: -35°C to +85°C
- Proximitor Storage Temperature: -35°C to +100°C
- Maximum Field Wiring Distance: 305 meters from Proximitor to monitoring system
Material Composition
Cast aluminum housing with hard anodized surface treatment, internal circuit board with conformal coating for moisture protection, and SpringLoc terminal block for field wiring connections.
Structural Characteristics
The Proximitor features a compact cast aluminum enclosure designed for panel mounting. The SpringLoc terminal block allows secure field wiring connections without the need for special installation tools. The screwless terminal design prevents loosening over time, ensuring reliable long-term connections. The mounting base provides built-in electrical insulation. The 9.0 meter system configuration requires precise matching of the probe cable length and extension cable length to ensure signal integrity across the longer system length.
