扩展温度范围应用
扩展温度范围（ETR）探头和ETR延长电缆可用于探头引线或延长电缆可能超过标准177的应用C（350F） 温度规格。ETR探头的额定温度可扩展至218C（425F） ●●●●。ETR延长电缆额定值高达260C（500F） ●●●●。ETR探头和电缆都与标准温度探头和电缆兼容，例如，您可以使用带有330130延长电缆的ETR探头。ETR系统使用标准3300 XL前置器传感器。请注意，当您将任何ETR组件用作系统的一部分时，ETR组件将系统精度限制在ETR系统的精度范围内。1.一米系统不使用延长电缆。2.前置器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。3.当考虑使用此传感器系统进行转速表或超速测量时，请参考Bently Nevada*应用说明，在超速保护应用中使用涡流接近探头时的注意事项。3300 XL 8 mm组件可与非XL 3300 5 mm和8 mm组件在电气和物理上互换。尽管3300 XL前置器传感器的包装不同于其前代产品，但当与4孔安装底座一起使用时，其设计适合相同的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）。
连接器
3300 XL探头、延长电缆和前置器传感器具有耐腐蚀镀金ClickLoc*连接器。这些连接器只需要用手拧紧扭矩（拧紧时，连接器会“咔哒”作响），特殊设计的锁定机构可防止连接器松动。这些接头的安装或拆卸不需要专用工具。您可以订购已安装连接器保护器的3300 XL 8 mm探针和延长电缆。我们还可以为现场安装单独提供连接器保护器（例如，当应用程序必须通过限制性导管敷设电缆时）。我们建议为所有安装提供连接器保护器，以提高环境保护8。混合使用XL和非XL 3300系列5 mm和8 mm系统组件将系统性能限制在非XL 3300 5 mm和8mm传感器系统的规格范围内。6.3300系列5 mm探针（参考规范和订购信息p/n 141605-01）使用更小的物理包装，但与8 mm探针相比，不会减少侧视图间隙或端到端间距要求。当物理（非电气）限制不允许使用8mm探头时，使用该传感器。当您的应用需要窄侧视探头时，请使用3300 NSv*接近传感器系统（请参阅部件号147385-01的规格和订购信息）。
Extended Temperature Range Applications
An extended temperature range (ETR) probe and ETR extension cable are available for applications in which either the probe lead or extension cable may exceed the standard 177 C (350 F) temperature specification. The ETR probe has an extended temperature rating for up to 218 C (425 F). The ETR extension cable rating is up to 260 C (500 F). Both the ETR probe and cable are compatible with standard temperature probes and cables, for example, you can utilize an ETR probe with the 330130 extension cable. The ETR system uses the standard 3300 XL Proximitor Sensor. Note that when you use any ETR component as part of your system, the ETR component limits the system accuracy to the accuracy of the ETR system.1. One-metre systems do not use an extension cable. 2. Proximitor sensors are supplied by default from the factory calibrated to AISI 4140 steel. Calibration to other target materials is available upon request. 3. Consult Bently Nevada* Applications Note, Considerations when using Eddy Current Proximity Probes for Overspeed Protection Applications, when considering this transducer system for tachometer or overspeed measurements.3300 XL 8 mm components are both electrically and physically interchangeable with non-XL 3300 5 mm and 8 mm components. Although the packaging of the 3300 XL Proximitor Sensor differs from its predecessor, its design fits 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).
Connectors
The 3300 XL probe, extension cable, and Proximitor sensor have corrosion-resistant, gold-plated ClickLoc* connectors. These connectors require only finger-tight torque (the connectors will "click" when tight), and the specially-engineered locking mechanism prevents the connectors from loosening. These connectors require no special tools for installation or removal. You can order the 3300 XL 8 mm probes and extension cables with connector protectors already installed. We can also supply connector protectors separately for field installations (such as when an application must run the cable through restrictive conduit). We recommend connector protectors for all installations to provide increased environmental protection8.Mixing XL and non-XL 3300-series 5 mm and 8 mm system components limits system performance to the specifications for the non-XL 3300 5 mm and 8 mm Transducer System. 6. The 3300-series 5 mm probe (refer to Specifications and Ordering Information p/n 141605-01) uses smaller physical packaging, but does not reduce the side view clearances or tip-to-tip spacing requirements as compared to an 8 mm probe. It is used when physical (not electrical) constraints preclude the use of an 8 mm probe. When your application requires narrow side view probes, use the 3300 NSv* Proximity Transducer System (refer to Specifications and Ordering Information p/n 147385- 01).
