產品詳情介紹
A-B 80190-480-01-R驅動控制裝置
1.5 mm探針使用更小的物理包裝，同時提供與8 mm探針相同的線性范圍；然而，與8mm探頭相比，它不允許減少側視間隙或尖端間距要求。當物理（非電氣）限制無法使用8mm探頭時，如安裝在推力軸承墊或其他受限空間之間時，使用該探頭。當需要窄側視探頭時，請咨詢Bently Nevada銷售和服務專業人員。
2.8毫米探針在模制PPS塑料探針頭中提供了更厚的探針線圈封裝。這使得探針更加堅固。探針體的直徑越大，外殼越堅固。Bently Nevada建議盡可能使用8 mm探針，以提供最佳的抗物理濫用魯棒性。
3.3300 XL前置器傳感器可用，與非XL版本相比有許多改進。它在電氣和機械方面可以與非XL型互換，建議將其作為大多數應用的最佳可用技術。盡管3300 XL Proximitor傳感器的包裝不同于其前身，但它設計為在與4孔安裝底座一起使用時適合相同的4孔安裝模式，并將適合相同的安裝空間規格（當觀察到最小允許電纜彎曲半徑時）。更多信息，請咨詢規格和訂購信息（p/n 141194-01）或我們的Bently Nevada銷售和服務專業人員。
4.當XL和非XL組件混合時，系統性能僅限于非XL 3300系統的規格。
5.Proximitor?傳感器默認由工廠提供，校準為AISI 4140鋼。可根據要求對其他目標材料進行校準。
6.當考慮使用該傳感器系統進行轉速表或超速測量時，請參考Bently Nevada應用注釋AN085。
7.每根3300 XL延長電纜還配有硅膠帶，可以代替連接器保護器。在探頭至延伸電纜連接將暴露于汽輪機油的應用中，不建議使用硅膠帶。
規格
除非另有說明，以下規格適用于18°C至27°C（64°F至80°F）之間的接近傳感器系統，帶有-24 Vdc電源，10 k? 負載，一個AISI 4140鋼靶，一個探針間隙為1.27 mm（50 mils）。建議使用三芯屏蔽三芯電纜。3300接近傳感器和監視器之間的最大長度為305米（1000英尺）。當使用更長的現場布線長度或距離監控系統一定距離的外部安全屏障時，請參考性能規范155687，了解高頻信號衰減。
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 ? 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.
