速度傳感器
說明Bently Nevada Seismoprobe速度傳感器系統設計用于測量絕對（相對于自由空間）軸承箱、外殼或結構振動。雙線系統由傳感器和適當的電纜組成。Seismoprobe速度傳感器系列是使用動圈技術的雙線設計。它提供與傳感器振動速度成正比的電壓輸出。與固態速度傳感器相比，動圈傳感器對沖擊或脈沖激勵不太敏感，固態速度傳感器本身就是帶有嵌入式集成電子器件的加速度計。動圈換能器對沖擊或脈沖激勵不太敏感，對于某些應用來說是一個不錯的選擇。因為它們不需要外部電源，所以便于便攜式測量應用。對于大多數安裝，Bently Nevada的Velomitor速度傳感器系列采用固態技術，為套管速度測量應用提供了改進的性能和堅固性。文件：141626 Rev.L 9200和74712 Seismoprobe速度傳感器數據表Bently Nevada機械狀態監測可用類型有兩種類型的Seismorobe速度傳感器可用：L 9200：9200是一種雙線傳感器，適用于連續監測或與測試或診斷儀器一起定期測量。當與集成電纜選件一起訂購時，9200具有優異的耐腐蝕性，無需額外保護。l 74712：74712是9200的高溫版本。
傳感器
互連電纜可用于將9200和74712傳感器連接到其他儀器。這些電纜有各種長度，有或沒有不銹鋼鎧裝。訂購9200和74712 Seismoprobe速度傳感器時，預計大約六（6）周的交貨期。交付周期可能因組件可用性和配置而異。請聯系您當地的Bently Nevada代表，了解您特定訂單的預計交付時間。傳感器放置的測量外殼如果您正在測量機器外殼以確定傳感器的放置位置，請考慮您想要獲得的測量類型。大多數常見的機器故障，如不平衡或未對準，都源于轉子，通常會導致轉子振動增加。如果集成330500 Velomitor輸出以測量位移，則來自干擾和傳感器電路的電噪聲會被放大。噪聲會降低330500換能器的性能，并產生不準確的位移數據。為了獲得高質量的數據，計劃將傳感器定位在一個位置，該位置可以通過軸承箱或機殼最佳地檢測機器振動。選擇一個位置、接地和屏蔽，使振幅和頻率響應最大化，并減少不代表實際機器振動的數據。Bently Nevada提供工程服務，以確定放置傳感器的最佳位置。如果需要，我們也可以安裝傳感器。如需幫助，請聯系您當地的客戶服務代表或
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.
