Bently Nevada 330106-05-30-15-02-CN Proximitor Sensor

Description The Bently Nevada 330106-05-30-15-02-CN is a 3300 XL series Proximitor Sensor designed for use with 11 mm proximity probe systems. This advanced eddy-current transducer system converts the physical distance between the 11 mm probe tip and a rotating conductive target (such as a turbomachinery shaft) into a continuous, linear negative DC voltage output. The 11 mm platform is specifically engineered for applications requiring a wider linear measurement range than standard 5 mm or 8 mm systems can provide, making it a critical component for monitoring long-stroke axial displacement (thrust position) or high-amplitude radial vibration in large utility turbines, generators, and industrial compressors.   Commercial Availability & Procurement Details Product Condition: New Original (Factory Sealed Surplus) Warranty Period: 12-Month Comprehensive Warranty Worldwide Shipping: 1–3 business days via DHL Express, FedEx, or UPS Pricing Notice: Listed pricing is indicative and fluctuates based on global supply chains.

Parameter Value / Technical Specification Input Supply Voltage −24 V DC nominal (Acceptable operating range: −17.5 to −26 V DC) Current Consumption Less than 12 mA Linear Range 4.0 mm (160 mils); begins at roughly 0.5 mm (20 mils) from the probe face Scale Factor (ASF) 3.94 V/mm (100 mV/mil) nominal System Output Impedance 50 \ \Omega nominal Operating Temperature −51 to 100 °C (−60 to 212 °F) Storage Temperature −51 to 105 °C (−60 to 221 °F) Relative Humidity 100% condensing, non-submerged (with sealed connectors) Probe Compatibility 3300 XL 11 mm Proximity Probes only   Engineering Architecture & Calibration Notes Linear Range Comparison Unlike standard 8 mm probes that deliver a 7.87 V/mm (200 mV/mil) scale factor over a 2.0 mm window, the 330106 Proximitor Sensor is tuned for an 11 mm probe tip, yielding a scale factor of 3.94 V/mm (100 mV/mil). This halving of the voltage slope effectively doubles the linear measurement window to 4.0 mm (160 mils). This extended range is necessary for machinery where thermal expansion or heavy thrust changes cause the target shaft to move substantially along its axial path. System Matching Requirements The 05 option in this part number designates that the internal tuning circuitry is matched precisely to a 5.0-meter total electrical system length. To achieve the stated calibration accuracy: The combined physical length of the 11 mm probe and the extension cable must equal exactly 5.0 meters (e.g., a 1.0-meter integral probe cable paired with a 4.0-meter extension cable). Mismatching a 5.0-meter Proximitor with a 9.0-meter cable network alters the system impedance, rendering the output voltage slope inaccurate and generating false errors within the machinery protection monitor.

Ensure the aluminum Proximitor housing remains electrically isolated from the enclosure backplate. Use the factory-supplied isolation washers or DIN rail adapters to break ground loops. Intrinsic Safety Constraints: Because this module carries the 15 multi-agency hazardous area approval, it must be wired through an approved intrinsic safety barrier or galvanic isolator if deployed in a Class I, Division 1 (Zone 0/1) environment. Verify the entity parameters against the loop design drawings before powering the circuit. Coaxial Torque Limits: Hand-tighten the miniature coaxial connectors (ClickLoc style) between the probe, cable, and Proximitor, then apply a gentle quarter-turn with a proper connector wrench. Over-tightening will strip the internal gold-plated pins, while under-tightening introduces intermittent contact errors that manifest as false vibration spikes.   Frequently Asked Questions Can I connect a standard Bently Nevada 8 mm probe to this 330106 Proximitor? No. Connecting an 8 mm probe to an 11 mm Proximitor sensor will severely disrupt the eddy-current field generation. The internal oscillator and linearization circuitry inside the 330106 are mapped specifically to the physical surface area and inductive properties of the 11 mm probe tip. Cross-mixing components will result in an uncalibrated, non-linear output and trigger a “Not OK” fault condition on your monitoring rack. What target material is this system calibrated for out of the box? The system is factory-calibrated using an AISI 4140 target steel block. If the target area on your machine shaft is surfaced with a different material alloy (such as chrome-moly, 300-series stainless steel, or tungsten carbide coating), the scale factor will deviate from 3.94 V/mm (100 mV/mil). Consult the OEM datasheet for correction curves or execute a manual calibration loop test with a spindle micrometer to program proper compensation factors.
