速度传感器
说明Bently Nevada Seismoprobe速度传感器系统设计用于测量绝对（相对于自由空间）轴承箱、外壳或结构振动。双线系统由传感器和适当的电缆组成。Seismoprobe速度传感器系列是使用动圈技术的双线设计。它提供与传感器振动速度成正比的电压输出。与固态速度传感器相比，动圈传感器对冲击或脉冲激励不太敏感，固态速度传感器本身就是带有嵌入式集成电子器件的加速度计。动圈换能器对冲击或脉冲激励不太敏感，对于某些应用来说是一个不错的选择。因为它们不需要外部电源，所以便于便携式测量应用。对于大多数安装，Bently Nevada的Velomitor速度传感器系列采用固态技术，为套管速度测量应用提供了改进的性能和坚固性。文件：141626 Rev.L 9200和74712 Seismoprobe速度传感器数据表Bently Nevada机械状态监测可用类型有两种类型的Seismorobe速度传感器可用：L 9200：9200是一种双线传感器，适用于连续监测或与测试或诊断仪器一起定期测量。当与集成电缆选件一起订购时，9200具有优异的耐腐蚀性，无需额外保护。l 74712：74712是9200的高温版本。
传感器
互连电缆可用于将9200和74712传感器连接到其他仪器。这些电缆有各种长度，有或没有不锈钢铠装。订购9200和74712 Seismoprobe速度传感器时，预计大约六（6）周的交货期。交付周期可能因组件可用性和配置而异。请联系您当地的Bently Nevada代表，了解您特定订单的预计交付时间。传感器放置的测量外壳如果您正在测量机器外壳以确定传感器的放置位置，请考虑您想要获得的测量类型。大多数常见的机器故障，如不平衡或未对准，都源于转子，通常会导致转子振动增加。如果集成330500 Velomitor输出以测量位移，则来自干扰和传感器电路的电噪声会被放大。噪声会降低330500换能器的性能，并产生不准确的位移数据。为了获得高质量的数据，计划将传感器定位在一个位置，该位置可以通过轴承箱或机壳最佳地检测机器振动。选择一个位置、接地和屏蔽，使振幅和频率响应最大化，并减少不代表实际机器振动的数据。Bently Nevada提供工程服务，以确定放置传感器的最佳位置。如果需要，我们也可以安装传感器。如需帮助，请联系您当地的客户服务代表或
speed sensor
Explain that the Bently Nevada Seismoprobe speed sensor system is designed to measure absolute (relative to free space) bearing housing, housing, or structural vibration. The two-wire system consists of sensors and appropriate cables. The Seismoprobe speed sensor series is a two-wire design using dynamic coil technology. It provides a voltage output proportional to the vibration speed of the sensor. Compared with the solid state speed sensor, the moving coil sensor is less sensitive to shock or pulse excitation. The solid state speed sensor itself is an accelerometer with embedded integrated electronic devices. Dynamic coil transducer is not sensitive to shock or pulse excitation, which is a good choice for some applications. Because they do not require an external power supply, they are convenient for portable measurement applications. For most installations, Bently Nevada's Velomitor speed sensor family uses solid-state technology to provide improved performance and robustness for casing speed measurement applications.

L 9200 and 74712 Seismoprobe Speed Sensor Data Sheet Bently Nevada Mechanical Condition Monitoring Available Types There are two types of Seismoprobe speed sensors available: L 9200:9200 is a two-wire sensor that is suitable for continuous monitoring or regular measurement with test or diagnostic instruments. When ordered with the integrated cable option, the 9200 has excellent corrosion resistance and requires no additional protection. L 74712:74712 is the high-temperature version of 9200.

Interconnect cables can be used to connect 9200 and 74712 sensors to other instruments. These cables are available in various lengths, with or without stainless steel armor. When ordering the 9200 and 74712 Seismoprobe speed sensors, a lead time of approximately six (6) weeks is expected. Lead times may vary depending on component availability and configuration. Please contact your local Bently Nevada representative for the estimated delivery time for your specific order. Measurement enclosure for sensor placementIf you are measuring the machine enclosure to determine the placement of the sensor, consider the type of measurement you want to obtain. Most common machine failures, such as imbalance or misalignment, originate in the rotor and usually result in increased rotor vibration. If the 330,500 Velomitor output is integrated to measure displacement, electrical noise from the interference and sensor circuits will be amplified. Noise will degrade the performance of the 330500 transducer and produce inaccurate displacement data. In order to obtain high-quality data, it is planned to position the sensor in a position that can best detect machine vibration through the bearing housing or casing. Select a location, ground, and shield to maximize amplitude and frequency response and reduce data that does not represent actual machine vibration. Bently Nevada provides engineering services to determine the best location to place the sensor. If necessary, we can also install sensors.
