Technical Insights
The Bently Nevada 330701-00-50-50-02-CN operates on the eddy current principle. It measures the distance between the probe tip and the conductive target. The system's linear range is 2mm (80 mils). Its sensitivity is 7.87 mV/µm (200 mV/mil). The operating temperature ranges from -35°C to +177°C. The probe uses a 5.0mm or 8.0mm threaded case for mounting. Importantly, the target material affects the output scale factor. Specifically, you must adjust for 4140 steel targets. The system also requires a specific gap voltage. The standard initial gap is -9.0 Vdc. The probe's total case length is 50mm. This model includes a connector option. Furthermore, the cable length is 5.0 meters.
Installation & Maintenance
Proper installation ensures the 330701-00-50-50-02-CN performs accurately. First, inspect the probe and cable for physical damage. Next, install the probe using the correct torque. Do not over-tighten the mounting nut. Then, set the initial air gap. Adjust the probe to achieve -9.0 Vdc at the proximitor output. Use a calibrated micrometer for precise gap setting. Verify the target material matches your setup. Finally, secure the cable with appropriate clamps. Regularly check the cable integrity. Keep the probe tip clean from debris. Furthermore, periodically verify the gap voltage against your baseline. This confirms correct probe positioning. Remember to avoid twisting the cable during installation. This prevents internal wire breakage.
