TIDM-WLMOTORMONITOR — 無線馬達監控器參考設計

此參考設計受監控馬達和機器健康狀況的需求所啟發，可準確預測和安排維護（或更換），同時將工業生產期間的成本和停機時間降到最低。目前透過手持或有線壓電加速度計感測裝置，監控數百萬個工業馬達。超低功耗處理技術、無線電及壓電感測器微型化的最新進展，促成了開發和部署具無線功能的低成本小型馬達監控器。這些無線馬達監控器皆由電池壽命超過 10 年的鈕釦電池供電。這些系統提供與現有手持系統相同的寬頻靈敏度、收集振動資料並對這些資料進行頻譜分析。這種整合智慧可讓您在不易觸及的位置部署和監控這些系統。無線馬達監控參考設計採用兩種不同、但在電氣方面等效的體積來進行開發與測試。

這些外型尺寸包括：

  • 模組化外型
  • 尺寸精巧
