A-B 80190-480-01-R驱动控制装置
1.5 mm探针使用更小的物理包装，同时提供与8 mm探针相同的线性范围；然而，与8mm探头相比，它不允许减少侧视间隙或尖端间距要求。当物理（非电气）限制无法使用8mm探头时，如安装在推力轴承垫或其他受限空间之间时，使用该探头。当需要窄侧视探头时，请咨询Bently Nevada销售和服务专业人员。
2.8毫米探针在模制PPS塑料探针头中提供了更厚的探针线圈封装。这使得探针更加坚固。探针体的直径越大，外壳越坚固。Bently Nevada建议尽可能使用8 mm探针，以提供最佳的抗物理滥用鲁棒性。
3.3300 XL前置器传感器可用，与非XL版本相比有许多改进。它在电气和机械方面可以与非XL型互换，建议将其作为大多数应用的最佳可用技术。尽管3300 XL Proximitor传感器的包装不同于其前身，但它设计为在与4孔安装底座一起使用时适合相同的4孔安装模式，并将适合相同的安装空间规格（当观察到最小允许电缆弯曲半径时）。更多信息，请咨询规格和订购信息（p/n 141194-01）或我们的Bently Nevada销售和服务专业人员。
4.当XL和非XL组件混合时，系统性能仅限于非XL 3300系统的规格。
5.Proximitor®传感器默认由工厂提供，校准为AISI 4140钢。可根据要求对其他目标材料进行校准。
6.当考虑使用该传感器系统进行转速表或超速测量时，请参考Bently Nevada应用注释AN085。
7.每根3300 XL延长电缆还配有硅胶带，可以代替连接器保护器。在探头至延伸电缆连接将暴露于汽轮机油的应用中，不建议使用硅胶带。
规格
除非另有说明，以下规格适用于18°C至27°C（64°F至80°F）之间的接近传感器系统，带有-24 Vdc电源，10 kΩ 负载，一个AISI 4140钢靶，一个探针间隙为1.27 mm（50 mils）。建议使用三芯屏蔽三芯电缆。3300接近传感器和监视器之间的最大长度为305米（1000英尺）。当使用更长的现场布线长度或距离监控系统一定距离的外部安全屏障时，请参考性能规范155687，了解高频信号衰减。
1.A 5 mm probe uses smaller physical packaging while providing the same linear range as an 8 mm probe; however, it does not permit reduced sideview clearances or tip-to-tip spacing requirements compared to an 8 mm probe. It is used when physical (not electrical) constraints preclude the use of an 8 mm probe, such as mounting between thrust bearing pads or other constrained spaces. When narrow sideview probes are required, consult your Bently Nevada Sales and Service Professional.
2. 8 mm probes provide a thicker encapsulation of the probe coil in the molded PPS plastic probe tip. This results in a more rugged probe. The larger diameter of the probe body also provides a stronger, more robust case. Bently Nevada recommends the use of 8 mm probes when possible to provide optimal robustness against physical abuse.
3. A 3300 XL Proximitor Sensor is available and provides numerous improvements over the non-XL version. It is electrically and mechanically interchangeable with the non-XL version, and is recommended as best available technology for most applications. Although the packaging of the 3300 XL Proximitor sensor differs from its predecessor, it is designed to fit in the same 4-hole mounting pattern when used with the 4-hole mounting base, and will fit within the same mounting space specifications (when minimum permissible cable bend radius is observed). Consult Specifications and Ordering Information (p/n 141194-01) or our Bently Nevada Sales and Service Professional for more information.
4. When XL and non-XL components are mixed, system performance is limited to the specifications for the non-XL 3300 system.
5. Proximitor® Sensors are supplied by default from the factory calibrated to AISI 4140 steel. Calibration to other target materials is available upon request.
6. Consult Bently Nevada Applications Note AN085 when considering this transducer system for tachometer or overspeed measurements.
7. Silicone tape is also provided with each 3300 XL extension cable and can be used instead of connector protectors. Silicone tape is not recommended in applications where the probe-to-extension cable connection will be exposed to turbine oil.
Specifications Unless
otherwise noted, the following specifications are for a proximity transducer system between 18°C and 27°C (64°F to 80°F) with a -24 Vdc power supply, a 10 k Ω load, an AISI 4140 steel target, and a probe gapped at 1.27 mm (50 mils).Recommend using three-conductor shielded triad cable. 305 metres (1,000 feet) maximum length between 3300 Proximity Transducer and monitor. Consult Performance Specification 155687 for signal rolloff at high frequencies when using longer field wiring lengths or external safety barriers located some distance from the monitoring system.
