無線振動傳感器基礎(chǔ)知識
Wireless Vibration Sensor Basics
無線振動傳感器測量振動變化并及早檢測旋轉(zhuǎn)機器故障以避免故障。許多維護主管將振動傳感器用作其整體狀態(tài)監(jiān)測程序的一部分。這是因為大約 90% 的機器故障屬于以下四個主要類別之一：
? 錯位
? 不平衡
? 松動
? 軸承損壞
合適的無線振動傳感器可以捕捉到這些常見的機器故障。
無線振動傳感器使用 WiFi、LTE 或以太網(wǎng)等網(wǎng)絡(luò)連接將測量值連續(xù)傳輸?shù)杰浖?。例如，無線傳感器可以將數(shù)據(jù)發(fā)送到計算機化維護管理系統(tǒng) (CMMS) 軟件，在那里可以存儲和分析數(shù)據(jù)。
A wireless vibration sensor measures vibration changes and detects rotating machine failures early to avoid breakdowns. Many maintenance leaders use vibration sensors as part of their overall condition monitoring program. That’s because some 90 percent of machine faults fall into one of four main categories:
? Misalignment
? Imbalance
? Looseness
? Bearing damage
The right kind of wireless vibration sensors can catch those common machine faults.
A wireless vibration sensor uses a network connection like WiFi, LTE, or ethernet, to continuously transmit measurements to software. For instance, a wireless sensor may send data to computerized maintenance management system (CMMS) software where the data can be stored and analyzed.

振動傳感器的工作原理
How a Vibration Sensor Works
無線振動監(jiān)測傳感器從安裝它的機器生成振動信號，對其進(jìn)行轉(zhuǎn)換和處理，然后將實時數(shù)據(jù)發(fā)送到 Web 應(yīng)用程序。該資產(chǎn)管理軟件可讓維護團隊查看和分析數(shù)據(jù)趨勢，以及執(zhí)行數(shù)據(jù)分析。
通過無線振動監(jiān)測，傳感器可以跟蹤和記錄振動水平測量值，用于確定旋轉(zhuǎn)機械（如壓縮機和泵（驅(qū)動電機、從動裝置）以及皮帶、齒輪、軸、軸承和構(gòu)成機械系統(tǒng)的其他部件）的健康狀況。
如果無線振動傳感器檢測到振動變化超過預(yù)定閾值，則會自動觸發(fā)警報并發(fā)送給維護團隊成員。根據(jù)資產(chǎn)關(guān)鍵性（即對整體生產(chǎn)和運營的影響），決定立即安排維修或更換機械。
通知可以優(yōu)化維護計劃和人工，確保零件可用性，并最終避免資產(chǎn)故障。
A wireless vibration monitoring sensor generates a vibration signal from the machine where it’s mounted, converts and processes it, and then sends the real-time data to a web application. That asset management software lets maintenance teams view and trend data, as well as perform data analysis.
With wireless vibration monitoring, the sensor tracks and records vibration level measurements used to determine the health of rotating machinery such as compressors and pumps (drive motors, driven devices) and belts, gears, shafts, bearings, and other components that make up a mechanical system.
If a wireless vibration sensor detects a change in vibration that exceeds predetermined threshold levels, an alert is triggered automatically and sent to a maintenance team member. Based on the asset criticality, meaning the impact on overall production and operations, a determination is made to immediately schedule a repair or replace the machinery.
The notification enables optimization of maintenance schedules and labor, ensures parts availability, and ultimately avoids asset failure.
測量振動的不同方法
Different Ways to Measure Vibration
振動可以用三種不同的方式測量：位移、速度和加速度。
? 位移是物體從參考點移動的距離。它最適合測量低頻。
? 速度是位移隨時間的變化率，涵蓋廣泛的頻率范圍。它最適合診斷導(dǎo)致磨損和故障的疲勞力。
? 加速度是速度隨時間的變化率。它最適合測量非常高的頻率。
加速度計是最常見的振動傳感器之一，因為它們堅固耐用，并且很容易將加速度轉(zhuǎn)換為速度。
Vibration can be measured in three different ways: displacement, velocity, and acceleration.
? Displacement is the distance an object moves from a reference point. It’s best for measuring low frequencies.
? Velocity is the changing rate of displacement over time and covers a wide range of frequencies. It is best at diagnosing fatigue forces that cause wear and failure.
? Acceleration is the changing rate of velocity over time. It’s best for measuring very high frequencies.
Accelerometers are one of the most common vibration sensors because they’re rugged, and it’s easy to convert the acceleration to velocity.
振動傳感器為何如此重要
Why Vibration Sensors Are Important
使用有線和無線傳感器測量振動變化已成為工業(yè)維護和可靠性計劃中必不可少的環(huán)節(jié)。
當(dāng)機器意外停機時，成本可能很高。例如，軸不平衡可能導(dǎo)致聯(lián)軸器損壞，并導(dǎo)致需要更換整個電機。
Using wired and wireless sensors to measure vibration changes has become essential in industrial maintenance and reliability programs.
When a machine goes down unexpectedly, the costs can be high. For instance, a shaft imbalance can cause coupling damage and lead to an entire motor needing to be replaced.
測量振動以盡早發(fā)現(xiàn)機器故障：
Measuring Vibration to Catch Machine Faults Early:
? 降低能源成本
? 減少停機時間和人工成本
? 降低維護和更換成本
? 提高安全性
? Lowers energy costs
? Reduces downtime and labor costs
? Decreases maintenance and replacement costs
? Increases safety
設(shè)置無線振動傳感器
Setting up a Wireless Vibration Sensor
確定適當(dāng)?shù)恼駝觽鞲衅髟O(shè)置、環(huán)境條件和傳感器位置對于傳感器的正常運行至關(guān)重要。根據(jù)安裝類型、機器類型和軟件，一些振動傳感器易于設(shè)置，配置、調(diào)試和安裝后即可立即使用。相比之下，其他振動傳感器則更為復(fù)雜，因此咨詢專家通常會有所幫助。
Determining the proper vibration sensor setup, environmental conditions, and sensor location are critical to a properly functioning sensor. Depending on the type of mount, machine type, and software, some vibration sensors are easy to set up and can be used immediately once configured, commissioned, and installed. In contrast, others are more complex, so it’s often helpful to consult an expert.
選擇合適的無線振動傳感器
Choosing the Right Wireless Vibration Sensor
振動傳感器有很多種類型。無線振動監(jiān)測的選擇通常取決于組織的整體運營能力。機器或部件對生產(chǎn)的重要性以及應(yīng)用將有助于確定需要哪種無線振動傳感器。
例如，篩選傳感器通常安裝在半關(guān)鍵和其他重要機器上。它提供讀數(shù)以指示存在問題，并讓用戶知道機器是否需要檢查或維護。
分析振動傳感器通常用于更關(guān)鍵的資產(chǎn)。這些傳感器具有加速度計，可幫助測量數(shù)據(jù)中看到的幅度和模式的變化。需要高分辨率傳感器來提供分析所需數(shù)據(jù)的詳細(xì)信息。
There are a number of different types of vibration sensors. Wireless vibration monitoring choices usually depend on an organization’s overall operational capacity. How critical a machine or component is to production and the application will help determine which wireless vibration sensor is needed.
For instance, a screening sensor is usually mounted on semi-critical and other essential machinery. It provides readings to indicate a problem exists and lets users know if the machine needs to be inspected or maintained.
An analysis vibration sensor is generally used on more critical assets. These sensors have accelerometers that help measure changes in amplitude and patterns seen in the data. A high-resolution sensor is needed to provide the detail of the necessary data for analysis.
傳感器的設(shè)計、尺寸和范圍多種多樣，因此非常靈活。了解期望測量的數(shù)據(jù)特征以及任何環(huán)境限制有助于確定哪種傳感器最適合預(yù)期用途。
There are many designs, sizes, and ranges of sensors to choose from, making them highly flexible. Understanding the data characteristics you expect to measure, and any environmental constraints can help decide which one fits the intended use best.
