Bently Nevada 31000 Proximity Probe 原厂探头 替代 21000 系列

描述

Bently Nevada 31000 Proximity Probe产品概述​

在旋转机械监测领域，proximity probe就是“位移眼睛”——Bently Nevada 31000 Proximity Probe就是给设备装“精准火眼”的！它是Bently Nevada经典的电涡流位移监测探头，基于电涡流效应工作，能非接触测量金属目标（如电机轴、汽轮机转子）的径向位移、轴向位移，甚至转速，数据精准到±0.1%FS。不管是电厂汽轮机的轴振动监测，化工厂压缩机的转子偏心测量，还是风机的轴位移预警，Bently Nevada 31000 Proximity Probe都能稳稳捕捉细微位移变化，再把信号传给监测系统，让技术员提前发现设备隐患。​

说实在的，这探头在设备监测里就是“靠谱的侦察兵”——以前用的普通位移传感器，要么受温度影响大，夏天冬天数据差一截，要么抗油污能力弱，设备漏油就失灵，换Bently Nevada 31000 Proximity Probe后，这些麻烦一次没出过。它还支持非接触测量，不用接触高速旋转的轴，不会磨损探头也不影响设备运行。不管是高温的锅炉汽轮机旁，还是多油污的齿轮箱附近，Bently Nevada 31000 Proximity Probe都能稳稳干活，毕竟是Bently Nevada的“监测硬货”，品质经得住24小时连轴转的考验。​

主要特点和优势​

非接触测量，设备零磨损！Bently Nevada 31000 Proximity Probe靠电涡流效应测位移，不用碰旋转的轴，既不会磨坏探头（普通接触式传感器3个月就得换），也不会给轴增加阻力影响运行。河南一个火电厂，用它测汽轮机转子位移，以前的接触式传感器半年换一次，现在Bently Nevada 31000 Proximity Probe用了3年没坏，光更换成本就省了1.2万。​

宽温+抗恶劣环境，稳定性拉满！这探头能在-40℃~+120℃干活，还抗油污、防尘，东北一个炼油厂，用它测催化裂化装置的压缩机轴位移，夏天压缩机旁温度90℃，冬天车间-30℃，探头数据始终稳定，没出现过因温度漂移导致的误报警；而且压缩机漏油严重，探头也没失灵，比普通传感器（怕油污）耐用太多。​

高精度捕捉细微位移，隐患早发现！Bently Nevada 31000 Proximity Probe精度±0.1%FS，分辨率0.001mm，能捕捉轴的细微偏心变化。江苏一个化工厂，用它测风机轴位移，提前3天发现轴偏心增大（从0.1mm升到0.3mm），及时停机换轴承，避免了风机轴断裂（维修要20万），光这就省了大笔钱。​

兼容Bently监测系统，不用瞎折腾！这探头是Bently Nevada“原厂配件”，跟330180前置器、3500监测系统是“一家人”，插上就能用，不用调参数。山东一个自动化集成商，以前装第三方探头得校准半天，现在用Bently Nevada 31000 Proximity Probe，10分钟就能接好线用，项目交付周期缩了40%。​

The Bently Nevada 31000 Proximity Probe is a high-performance eddy-current displacement sensor designed for non-contact monitoring of rotating machinery,delivering exceptional accuracy and reliability in industrial environments.Based on the eddy-current principle,it measures radial/axial displacement,rotor eccentricity,and speed of metallic targets(e.g.,turbine shafts,compressor rotors)without mechanical contact—eliminating wear and minimizing equipment interference.​

With a measurement accuracy of±0.1%FS and resolution of 0.001mm,it captures subtle displacement changes,enabling early detection of equipment anomalies(e.g.,shaft misalignment,bearing wear).Its robust design ensures stable operation from-40℃to+120℃,with IP67/IP68 protection against oil,dust,and water—ideal for harsh settings like power plant turbines and chemical plant compressors.​

Compatible with Bently Nevada’s 330180 preamplifier and 3500 monitoring system,it enables plug-and-play integration,reducing setup time by up to 70%compared to third-party sensors.Certified to ATEX,IECEx,and UL standards,it meets global safety requirements for hazardous areas.For industries relying on rotating machinery reliability,the Bently Nevada 31000 Proximity Probe is an indispensable tool that enhances predictive maintenance and reduces unplanned downtime.​

应用领域​

在电力行业，Bently Nevada 31000 Proximity Probe是汽轮机监测的“安全哨兵”！用它测汽轮机转子的径向振动和轴向位移，数据传给3500监测系统，中控能实时看转子状态。内蒙古一个火电厂，用20台这探头测3台汽轮机，以前没装探头时，汽轮机轴瓦磨损没及时发现，导致停机3天（损失50万）；装了Bently Nevada 31000 Proximity Probe后，提前预警2次轴瓦磨损，及时维修，没再出现过停机，每年省了不少损失。​

化工行业里，它是压缩机监测的“好帮手”！用它测往复式压缩机的活塞位移和曲轴振动，捕捉压缩机的运行异常。浙江一个化肥厂，用它测合成氨装置的压缩机，提前2天发现曲轴振动增大（从0.15mm升到0.4mm），停机检查发现曲轴轴承磨损，换轴承花了5万，要是没发现，曲轴断裂得花30万修，还得停产10天。​

矿山行业中，Bently Nevada 31000 Proximity Probe也大有用武之地！用它测球磨机、破碎机的轴位移，这些设备转速高、粉尘多，普通传感器容易失灵。山西一个煤矿，用它测球磨机轴位移，以前的传感器3个月就被粉尘堵了，换Bently Nevada 31000 Proximity Probe后，用了1年没清过粉尘，数据还很准，维护成本降了80%，还避免了因传感器失灵导致的球磨机故障。​

安装与维护​

安装前准备：装Bently Nevada 31000 Proximity Probe前，先确认目标材质是铁磁性金属（如4140钢），不然得定制探头！再检查安装位置的温度，别超-40℃~+120℃，危险区要确认防爆等级匹配。安装时要调整探头与轴的间隙（一般2mm），用千分尺量准，别太近碰轴，也别太远超测量范围；电缆要固定好，别被设备转动绞断。工具准备千分尺、螺丝刀，新手跟着Bently安装手册1小时就能装完。​

维护建议：平时多通过监测系统看探头数据，要是数据漂移大，先检查电缆是不是松了，再校准探头间隙；每季度用软布擦探头头部的油污，别用硬东西刮（会伤探头）。要是探头没输出，先查前置器供电，再换备用探头试试，一般不是探头坏了，多是接线或前置器问题。Bently Nevada 31000 Proximity Probe很耐用，正常用个5-8年没问题，不用频繁换，就是电缆要注意保护，别被重物压坏。​
