Bently Nevada Module330180-91-05

The Bently Nevada 330180-91-05 is a 3300 XL Series Proximitor® Sensor—the signal conditioning component of the 3300 XL eddy current transducer system. It converts the high-frequency impedance signal from the proximity probe into a linear DC voltage proportional to the gap between the probe tip and the target surface. This processed signal is then used for vibration, position, and speed monitoring on critical rotating machinery such as turbines, compressors, pumps, and electric motors.

Key Features

Feature	Description
System Length	Designed for a 9.0-meter total system length (probe + extension cable). The entire probe–extension cable–proximitor loop must have a consistent electrical length for accurate measurement.
Sensitivity	7.87 V/mm (200 mV/mil) — provides high-resolution measurement for precise dynamic displacement tracking.
Linear Range	2.0 mm (80 mils) , covering a measurement span from approximately 0.25 mm to 2.3 mm.
Frequency Response	0 – 10 kHz (+0, -3 dB), suitable for capturing vibration signals in most rotating machinery applications.
Operating Temperature	–52 °C to +100 °C (–62 °F to +212 °F), enabling use in extreme industrial environments.
Power Supply	–17.5 VDC to –26 VDC (without safety barrier); –23 VDC to –26 VDC (with safety barrier). Maximum current draw: 12 mA.
Mounting	Compatible with 35 mm DIN rail and panel mounting. The mounting base provides electrical isolation, eliminating the need for separate isolator plates.
Connector	Gold-plated ClickLoc™ connector for corrosion resistance and secure signal transmission.
Protection Rating	IP67 (environmental sealing).
Agency Approvals	The -05 suffix indicates multi-agency hazardous area approvals, including CSA/NRTL/C Class I, Division 2, as well as ATEX and IECEx certification.

Model Number Breakdown

Segment	Meaning
330180	Base model — 3300 XL Proximitor® Sensor (signal conditioner)
91	Configuration: 9.0 m system length with DIN-rail mount
05	Hazardous area approval package (CSA/NRTL/C, ATEX, IECEx)

System Compatibility

The 330180-91-05 is part of the 3300 XL 8 mm eddy current transducer system and must be used with matching components:

Component	Description
Probe	3300 XL 8 mm proximity probe (e.g., 330101, 330103 series)
Extension Cable	3300 XL extension cable (e.g., 330130 series)
Total System Length	Must equal 9.0 meters (probe + extension cable) for this model.

Important: All components in the system must have consistent electrical lengths. Using a 9.0 m proximitor with a shorter probe/cable combination will result in significant measurement errors and nonlinear output.
