Description：

The Bently Nevada 330180-X1-05 MOD:145004-94 3300 XL Proximitor Sensor is a key signal processing unit used in the 3300 XL 8 mm proximity transducer system. It works together with a compatible eddy current proximity probe and extension cable to detect shaft displacement in rotating machinery. The sensor receives the high-frequency signal generated by the probe and converts the measurement data into a proportional DC voltage output, allowing monitoring systems to accurately determine the gap between the probe tip and the conductive machine surface.

This specific configuration features a 5.0-meter total system length with DIN rail mounting. The –05 suffix denotes full CSA, ATEX, and IECEx hazardous area certifications. The MOD:145004-94 factory modification indicates a specific hardware or firmware revision applied during manufacturing.

Frequently asked questions

Q1: What does MOD:145004-94 mean?

It overrides the default AISI 4140 steel calibration. The sensor's internal circuitry is factory-tuned specifically for the magnetic permeability and conductivity of AISI 4340 high-strength alloy steel (commonly used in heavy-duty shafts and gearboxes).

Q2: Can I use a standard 330180 sensor instead?

No. Using a standard sensor on a 4340 steel target distorts the eddy-current scaling. This causes severe measurement errors, incorrect gap voltages, and inaccurate vibration readings.

Q3: Can I alter this calibration in the field?

No. The AISI 4340 calibration is permanently hard-wired into the sensor's physical circuitry at the factory. It cannot be modified via software, trim pots, or field calibration tools.

Q4: What probes and cables are compatible?

The -05 suffix restricts this unit strictly to a 5-meter total electrical loop. You must pair it with a 3300 XL 8mm probe and extension cable that combine to equal exactly 5.0 meters in length.
