        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        What is the exact field wiring length limitation for the Bently Nevada 330980-71-05, and how does it affect frequency response?
        The Bently Nevada 330980-71-05 supports field wiring up to 305 meters (1,000 feet) between the sensor and monitor. However, longer wiring reduces high-frequency response: at 305 meters, signal rolloff begins above 2 kHz with -3 dB attenuation at approximately 4 kHz. For full 0-10 kHz response, keep field wiring under 30 meters.
        Can the Bently Nevada 330980-71-05 interface directly with a 3500 Series monitoring system?
        Yes. The Bently Nevada 330980-71-05 outputs a standard -1 to -13 Vdc signal that is directly compatible with Bently Nevada 3500/40M Proximitor Monitor modules, as well as third-party PLCs (Rockwell, Siemens, Emerson) via analog input cards configured for 0 to -24 Vdc range. No signal conditioning is required for direct integration.
        What are the diagnostic capabilities of the Bently Nevada 330980-71-05 for open-circuit detection?
        The Bently Nevada 330980-71-05 includes automatic open-circuit detection: if the probe or extension cable is disconnected, the output voltage shifts to a
        How do I verify the Bently Nevada 330980-71-05 is calibrated correctly for non-AISI 4140 steel targets?
        By default, the Bently Nevada 330980-71-05 is factory-calibrated for AISI 4140 steel targets. For other materials (e.g., titanium, Inconel, stainless steel), you must request custom calibration at order time. Aftermarket recalibration is available through Bently Nevada service centers using material-specific target samples.
        What are the minimum shaft diameter requirements for using the Bently Nevada 330980-71-05 in radial vibration measurements?
        For radial vibration measurements, the Bently Nevada 330980-71-05 requires a minimum shaft diameter of 30 mm (1.2 inches) for standard X-Y probe configurations, or 20 mm (0.8 inches) when probes are offset axially by 23 mm. Below these diameters, scale factor deviation exceeds 10%, requiring custom calibration or reduced gap settings.
        What hazardous area certifications does the Bently Nevada 330980-71-05 carry?
        The Bently Nevada 330980-71-05 with -05 approval option carries multiple certifications: ATEX Ex ia IIC T4/T5 Ga (Zone 0), IECEx Ex ia IIC T4/T5 Ga, CSA/NRTL/C Class I Div 1 Groups A-D, and SIL 2/SIL 3 capable (per IEC 61508). For Zone 2 installations, non-incendive ratings (Ex nA/ec) are also available. Always refer to drawings 141092 (intrinsic safety) or 140979 (non-incendive) for barrier requirements.
