该系统提供的输出电压与探头与观察到的导电表面之间的距离成正比，可以测量静态(位置)和动态(振动)值。该系统的主要应用是振动和位置测量流体膜轴承机，以及关键相量*参考和速度测量3。
3300 XL 8毫米系统在我们的涡流接近传感器系统中提供了的性能。标准的3300 XL 8毫米5米系统也符合美国石油协会(API) 670标准
机械配置，线性范围，精度和温度稳定性标准(第4版)。所有3300 XL 8mm近距离传感器系统都提供这种级别的性能，并支持探头，延长电缆和Proximitor传感器的互换性，无需匹配或台架校准单个组件。
每个3300 XL 8mm传感器系统组件向后兼容和可互换4与其他非XL 3300系列5mm和8mm传感器系统组件5。这种兼容性包括3300 5毫米探头，用于8毫米探头对可用安装空间太大的应用6,7。
Proximitor传感器
3300 XL Proximitor传感器与以前的设计相比进行了许多改进。它的物理包装允许您在高密度的DINrail安装中使用它。您也可以将传感器安装在传统的面板安装配置中，其中它与旧的Proximitor传感器设计共享相同的4孔安装“足迹”。安装基础的任何一个选项提供电气隔离，消除了需要单独的隔离板。3300 XL Proximitor传感器对射频干扰具有高度免疫力，可以将其安装在玻璃纤维外壳中，而不会对附近的射频信号产生不利影响。3300 XL Proximitor传感器改进的RFI/EMI抗扰度满足欧洲CE标志认证，无需特殊屏蔽导管或金属外壳，从而降低了安装成本和复杂性。
3300 XL的SpringLoc端子条不需要特殊的安装工具，通过消除可松动的螺杆式夹紧机构，可以实现更快、更坚固的现场接线连接。

The system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface and can measure both static (position) and dynamic (vibration) values. The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor* reference and speed measurements3.
The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems. The standard 3300 XL 8 mm 5-metre system also fully complies with the American Petroleum Institute’s (API) 670
Standard (4th Edition) for mechanical configuration, linear range, accuracy, and temperature stability. All 3300 XL 8 mm proximity transducer systems provide this level of performance and support complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need to match or bench calibrate individual components.
Each 3300 XL 8 mm Transducer System component is backward-compatible and interchangeable4 with other non-XL 3300 series 5 mm and 8 mm transducer system components5. This compatibility includes the 3300 5 mm probe, for applications in which an 8 mm probe is too large for the available mounting space6,7.
Proximitor Sensor
The 3300 XL Proximitor Sensor incorporates numerous improvements over previous designs. Its physical packaging allows you to use it in high-density DINrail installations. You can also mount the sensor in a traditional panel mount configuration, where it shares an identical 4-hole mounting “footprint” with older Proximitor Sensor designs. The mounting base for either option provides electrical isolation and eliminates the need for separate isolator plates. The 3300 XL Proximitor Sensor is highly immune to radio frequency interference, allowing you to install it in fiberglass housings without adverse effects from nearby radio frequency signals. The 3300 XL Proximitor Sensor’s improved RFI/EMI immunity satisfies European CE mark approvals without requiring special shielded conduit or metallic housings, resulting in lower installation costs and complexity.
The 3300 XL’s SpringLoc terminal strips require no special installation tools and facilitate faster, more robust field wiring connections by eliminating screw-type clamping mechanisms that can loosen.
