3300 XL Series 8mm Sensor Installation & Maintenance Guide
Product Introduction
The Bently Nevada 330191-00-56-10-00 belongs to the 3300 XL 8mm Proximity Transducer System. This model features a long 5.6-inch (142 mm) case length and a 1.0-meter integrated cable. Specifically, the part number breaks down as follows: "330191" identifies the 8mm ETR probe with a 3/8-24 UNF thread and no armor. "00" means no cable armor protection. "56" specifies the 5.6-inch case length. "10" indicates the 1.0-meter cable. Finally, "00" denotes no agency approvals.
This sensor operates with a power supply between -17.5 Vdc and -26 Vdc. The optimal performance range lies between -23.5 Vdc and -26 Vdc. Moreover, the probe supports a wide temperature range from -55°C to +232°C. It also provides a cable pull strength of 330 Newtons minimum. The tip diameter is 8 mm, and the thread size is 3/8-24 UNF.
Core Value
This probe delivers precise vibration and position measurements. Its primary role is to protect critical rotating machinery. You can use it in steam and gas turbines. It also works well in compressors, pumps, and gearboxes. Furthermore, the 330191-00-56-10-00 provides accurate shaft vibration data. It also offers reliable shaft position and bearing temperature information. The probe’s extended temperature range ensures performance in harsh environments. Therefore, this sensor helps you prevent unexpected downtime. It also reduces costly maintenance interventions. Ultimately, the probe extends the operational life of your equipment.
Technical Insights
The 3300 XL system uses eddy current technology for non-contact measurement. Specifically, the probe generates a high-frequency magnetic field from its tip. This field induces eddy currents on the conductive shaft surface. Consequently, the probe measures the distance to the shaft with high precision. The linear range of this probe covers from 0.25 mm to 2.29 mm. Moreover, its sensitivity is 7.87 V/mm.
You must pair the Bently Nevada 330191-00-56-10-00 with a compatible driver. The 3300 XL driver provides the necessary RF excitation. It also demodulates the signal for your monitoring system. The total system accuracy is very high, reaching ±0.66% of the full scale. Additionally, the cable length affects the calibration. Therefore, always use the exact length specified in the order. This ensures proper gap voltage and scaling.
Installation & Maintenance
Proper installation is crucial for accurate readings. First, choose a clean and flat target area on the shaft. The surface should have no scratches or runout. Secondly, mount the probe using the 3/8-24 UNF threads. Apply recommended torque, typically 20 to 25 Nm. The probe gap is very important. Set the initial air gap between 0.51 mm and 1.02 mm. This corresponds to a voltage reading of -7.0 Vdc to -10.0 Vdc.
Furthermore, ensure the cable has a proper bend radius. Avoid sharp bends to prevent signal degradation. Securely connect the Bently Nevada 330191-00-56-10-00 to the extension cable. Use the connector tightening tool for a secure fit. For maintenance, regularly inspect the probe tip. Remove any debris or oil buildup. Also, check the cable insulation for damage. Periodically verify the gap voltage during routine shutdowns. This confirms the probe remains stable over time.
