稱重傳感器，也可稱為負(fù)載單元，稱重單元。是大多數(shù)工業(yè)稱重系統(tǒng)中的關(guān)鍵部件。稱重傳感器最基本的定義是，它們測(cè)量重量(或者更準(zhǔn)確地說是方向力）通常是通過彈簧元件和應(yīng)變片的組合，轉(zhuǎn)換為電氣輸出。在各種不同類型的稱重傳感器中，可以通過兩種關(guān)鍵方式區(qū)分不同的型號(hào)和樣式:①通過他們用于檢測(cè)重量的方法（拉壓稱重傳感器、張力稱重傳感器和其他測(cè)量類型)②按輸出信號(hào)的類型生成(液壓稱重傳感器、壓電載荷單元和各種其他配置)，嚴(yán)格地說，任何類型的稱重傳感器都始終設(shè)計(jì)為在重力方向上工作。但是，在參考各種力感應(yīng)設(shè)備類型時(shí)使用”稱重傳感器”這一術(shù)語(yǔ)是很常見的，其中許多設(shè)備被明確設(shè)計(jì)用于測(cè)量從四面八方施加的力。這些術(shù)語(yǔ)在當(dāng)今許多工作場(chǎng)所環(huán)境中已在很大程度上可以互換，因此在評(píng)估稱重稱重傳感器或計(jì)劃購(gòu)買稱重傳感器部件時(shí)，準(zhǔn)確的說明要用于應(yīng)用的設(shè)備類型是必要的。
為什么要使用稱重傳感器?
稱重傳感器在當(dāng)今大多數(shù)重工業(yè)、制造工廠、大型生產(chǎn)車間和嚴(yán)格的質(zhì)量控制環(huán)境中被廣泛適用。在全球銷售中，大部分的應(yīng)用仍然依賴于精確的重量測(cè)量，這是稱重傳感器在現(xiàn)代商業(yè)中扮演如此重要角色的一個(gè)原因。在更直接的工業(yè)用途中，稱重傳感器對(duì)于維護(hù)精確的質(zhì)量控制系統(tǒng)，促進(jìn)制造一致性和安全過程極為重要。它們還廣泛應(yīng)用于各種醫(yī)療和實(shí)驗(yàn)室環(huán)境，以實(shí)現(xiàn)用于各種科學(xué)和研究目的的最佳精確測(cè)量。稱重傳感器在一系列行業(yè)中正迅速變得更為普遍，這些行業(yè)本質(zhì)上不太依賴精確重量測(cè)量，例如在一股物流和貨運(yùn)計(jì)算中。稱重傳感器技術(shù)與多種其他數(shù)字和基于計(jì)算機(jī)的通信技術(shù)本質(zhì)上是兼容的，使所有類型的公司能夠?qū)崟r(shí)快速訪問、監(jiān)控和響應(yīng)關(guān)鍵診斷信息。由于使用傳統(tǒng)的機(jī)械平臺(tái)稱重設(shè)備要做到這一點(diǎn)要困難得多，因此從長(zhǎng)遠(yuǎn)來看，對(duì)大多數(shù)公司來說，安裝稱重傳感器往往更為高效且具有成本效益。
稱重傳感器的工作原理是什么?
T業(yè)應(yīng)用中最常用的稱重器類型是應(yīng)變片。應(yīng)變片稱重傳感器由固定應(yīng)變片的固體金屬體(或”彈簧元件”）組成。應(yīng)用負(fù)載時(shí)，稱重傳感器的主體輕微變形并偏轉(zhuǎn)。偏轉(zhuǎn)是指應(yīng)用負(fù)載時(shí)，負(fù)載單元沿主軸的長(zhǎng)度變化。在拉壓力稱重傳感器中，偏轉(zhuǎn)使儀表變短變厚。在張力稱重傳感器中，儀表被拉伸，變長(zhǎng)變薄。為了響應(yīng)體型的變化，應(yīng)變片也會(huì)改變形狀。這反過來又會(huì)導(dǎo)致應(yīng)變片的電阻變化，然后可以測(cè)量為電壓變化。由于輸出的這種變化與施加的重量量成正比，因此可以從電壓變化中確定物體的重量。
The Pressductor PillowBlock horizontal load cell is ideal for applications with low tension, heavy mixing and high operating speeds, which are often encountered in the paper industry. The pillow is available in three models: the standard model, PFTL101A/B, which is commonly used for precise measurements in the paper industry, such as paper machines, calenders, coaters and winders.
The factory load version of PFTL101AE/BE is recommended for web tension measurement in the dryness of paper machines. This version has a fixed connection cable and protection grade IP66, providing accurate and reliable measurements with a long service life.
The acid-resistant PFTL 101AER/BER is designed for the wet end of paper machines and is rated IP 66/67. What is a load cell?
Load cell, also known as load cell, load cell. It is a key component in most industrial weighing systems. The most basic definition of load sensors is that they measure weight (or, more accurately, directional force) usually through a combination of spring elements and strain gauges, converted into an electrical output. Among the various types of load cells, different models and styles can be distinguished in two key ways :① by the method they are used to detect weight (tension load cells, tension load cells, and other measurement types)② generated by the type of output signal (hydraulic load cells, piezoelectric load cells, and various other configurations), strictly speaking, Any type of load cell is always designed to operate in the direction of gravity. However, it is common to use the term "load cell" when referring to various force-sensing device types, many of which are explicitly designed to measure forces applied from all sides. These terms have become largely interchangeable in many workplace environments today, so an accurate description of the type of equipment to be used for the application is necessary when evaluating a load cell or planning to purchase load cell parts.
Why use a load cell?
Load cells are widely used today in most heavy industries, manufacturing plants, large production workshops and strict quality control environments. In global sales, the majority of applications still rely on accurate weight measurement, which is one reason why load sensors play such an important role in modern business. In more immediate industrial uses, load sensors are extremely important for maintaining accurate quality control systems that promote manufacturing consistency and safe processes. They are also widely used in a variety of medical and laboratory Settings to achieve optimal precision measurements for a variety of scientific and research purposes. Load sensors are rapidly becoming more common in a range of industries that inherently rely less on precise weight measurement, such as in a stream of logistics and freight calculations. Load cell technology is inherently compatible with a variety of other digital and computer-based communication technologies, enabling companies of all types to quickly access, monitor and respond to critical diagnostic information in real time. Since this is much more difficult to do using traditional mechanical platform weighing equipment, installing weighing sensors tends to be more efficient and cost-effective for most companies in the long run.
How does the load cell work?
The most common type of scale used in industrial applications is the strain gauge. The strain gauge load cell consists of a solid metal body (or "spring element") that holds the strain gauge in place. When the load is applied, the body of the load cell is slightly deformed and deflected. Deflection refers to the variation of the load unit along the length of the spindle when the load is applied. In a tension pressure load cell, deflection makes the meter shorter and thicker. In a tension load cell, the meter is stretched, lengthened and thinned. In response to changes in body shape, the strain gauge also changes shape. This in turn causes a change in the resistance of the strain gauge, which can then be measured as a voltage change. Since this change in the output is proportional to the amount of weight applied, the weight of the object can be determined from the voltage change.
