Calibration and Accuracy Specifications

Unless otherwise noted, these specifications apply under specific conditions. Specifically, the system uses a -24 Vdc power supply. A 10 kΩ load is connected to the output. The target must be Bently Nevada AISI 4140 steel (31 mm diameter or larger). Probe gap is set to 1.0 mm (40 mils). Temperature range for these specs is 0°C to +45°C (+32°F to +113°F). Maximum altitude is 2000 meters. Importantly, system accuracy and interchangeability specifications do not apply with other target materials. Therefore, always use a Bently Nevada AISI 4140 steel target for rated performance.

Key Features of 330980-70-05

The Bently Nevada 330980-70-05 offers improved RFI/EMI immunity. Consequently, European CE mark approvals are achieved without special mounting considerations. Nearby high frequency radio signals cannot adversely affect this transducer system. SpringLoc terminal strips require no special installation tools. These strips facilitate faster and more robust field wiring connections. Additionally, screw-type clamping mechanisms are eliminated. Such mechanisms can loosen over time in vibrating environments. The thin design allows high-density mounting in crowded cabinets. For panel mount configuration, the 7.0 meter system length provides installation flexibility. The A380 aluminum housing provides durability with low weight.

Installation Guidelines for 330980-70-05

Before starting, disconnect all power to your monitoring system. Choose either DIN-rail or panel mount configuration. For panel mount, use the appropriate mounting holes on the housing. Then, secure the Bently Nevada 330980-70-05 using suitable hardware. Connect your 3300 RAM or 3300 NSv probe to the input. Ensure the extension cable is properly secured. Wire the power supply within the specified voltage range. Without barriers, use -17.5 Vdc to -26 Vdc. With barriers, use -23 Vdc to -26 Vdc exclusively. Verify the supply voltage does not exceed -23.5 Vdc for linear operation. For hazardous area installations, follow all CSA, ATEX, and IECEx requirements. After all connections are made, test the output signal for proper response at the recommended gap setting.

Application Scenarios for 330980-70-05

The Bently Nevada 330980-70-05 monitors vibration in hazardous area turbomachinery. Steam turbines and gas turbines benefit from its ATEX approval. Compressors in refineries use the CSA certification for safe operation. The panel mount configuration suits traditional control cabinet installations. With 7.0 meter system length, the Proximitor Sensor mounts safely in non-hazardous control rooms. Meanwhile, the probe remains in the hazardous machine area. Consequently, this configuration simplifies maintenance and improves safety. The 330980-70-05 operates reliably from -52°C to +100°C. Therefore, extreme environment applications are well supported.
