BENTLY 330180-90-00 Eddy Current Sensor

Bently 330180-90 (3300 XL preamplifier/eddy current sensor system)
Belonging to the core preamplifier of Bentley’s classic 8mm eddy current monitoring system, it is used for collecting shaft vibration/displacement/key phase signals of rotating machinery.

1、 Basic Information
Model: 330180-90
Brand: Bently Nevada (currently owned by Baker Hughes)
Series: 3300 XL 8mm Eddy Current Sensor System
Type: Proximitor Sensor
Purpose: Used in conjunction with 3300 XL 8mm probe and extension cable to measure shaft vibration, axial displacement, eccentricity, and key phase signals
Status: Active (in production), original factory supply is normal, new stock is sufficient
Standard: Meets the requirements of API 670 (4th edition) for mechanical protection systems
2、 System composition (3300 XL 8mm complete chain)
Probe: such as 330104-00-05-10-02-00 (8mm, 5m cable)
Extension Cable: such as 330130-08-00 (8mm, 5m)
Proximitor: 330180-90 (9-meter total length adapter, panel mounted)
3、 Core technical parameters
Measurement range: 0-8mm (linear range 0.25-2.25mm)
Sensitivity: 7.87 V/mm (200 mV/mil), accuracy ± 0.01mm
Output signal:
DC: -4V to -24V (corresponding to displacement)
Communication: Vibration waveform (peak to peak)
Power supply: 17.5VDC to 26VDC (without safety barrier); 23VDC to 26VDC (with safety barrier), maximum 12mA
Temperature: Operating -40 ℃ to+85 ℃; Storage -55 ℃~+125 ℃
Protection: IP65; Anti radio frequency interference (RFI)
Size/Weight: Approximately 80 × 61 × 63mm, 1.8kg
Cable total length: Supports 9m (probe+extension cable)

4、 Key characteristics
Full interchangeability: probes, extension cables, and preamplifiers can be freely matched without the need for on-site calibration
Backward compatibility: compatible with old 3300 5mm/8mm non XL systems
Long distance transmission: Three core shielded wire can transmit 305 meters to the monitor (such as 3500/2300/1900)
High stability: Low temperature drift, suitable for high-speed rotating machinery such as steam turbines, compressors, gas turbines, etc
5、 Model discrimination and substitution
330180-90: Standard 9m adapter preamplifier (most commonly used)
330180-50-00:5m adaptation version
Upgrade Replacement: No direct replacement, 3300 XL is currently the mainstream; This model is still preferred for new projects
