什么是稱重傳感器？

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)分不同的型號和樣式：①通過他們用于檢測重量的方法（拉壓稱重傳感器、張力稱重傳感器和其他測量類型）②按輸出信號的類型生成（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)備類型時使用”稱重傳感器”這一術(shù)語是很常見的，其中許多設(shè)備被明確設(shè)計(jì)用于測量從四面八方施加的力。這些術(shù)語在當(dāng)今許多工作場所環(huán)境中已在很大程度上可以互換，因此在評估稱重稱重傳感器或計(jì)劃購買稱重傳感器部件時，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。在銷售中，大部分的應(yīng)用仍然依賴于精確的重量測量，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原因。在更直接的工業(yè)用途中，稱重傳感器對于維護(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)和研究目的的精確測量。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量，例如在一般物流和貨運(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)械平臺稱重設(shè)備要做到這一點(diǎn)要困難得多，因此從長遠(yuǎn)來看，對大多數(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？

工業(yè)應(yīng)用中的稱重器類型是應(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，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，負(fù)載單元沿主軸的長度變化。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，變長變薄。為了響應(yīng)體型的變化，應(yīng)變片也會改變形狀。這反過來又會導(dǎo)致應(yīng)變片的電阻變化，然后可以測量為電壓變化。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。

Silicon Controlled Rectifier (SCR) is a high-power electrical component, also known as a thyristor. It has the advantages of small size, high efficiency and long life. In the automatic control system, it can be used as a high power driving device to realize the control of high power equipment with low power control. It has been widely used in AC/DC motor speed regulating system, power regulating system and servo system.
Thyristor is divided into two kinds: one-way thyristor and two-way thyristor. Bidirectional thyristor is also called TRIAC, or Triac for short. Bidirectional thyristor is equivalent in structure to two one-way thyristor reverse connection, this thyristor has the function of double guide pass. Its on-off state is determined by the control pole G. Positive (or negative) pulse is added to the control pole G to make it positive (or reverse) conduction. The advantage of this device is that the control circuit is simple, no reverse voltage problem, so it is particularly suitable for AC contactless switch use.
We use the unidirectional thyristor, also known as the common thyristor, which is composed of four layers of semiconductor material, with three PN junction, external three electrodes (Figure 2(a)) : the first layer of P-type semiconductor led electrode called anode A, the third layer of P-type semiconductor led electrode called control pole G, the fourth layer of N-type semiconductor led electrode called cathode K. As can be seen from the circuit symbol of the thyristor (FIG. 2(b)), it is a single-direction conducting device like the diode. The key is that it has a control pole G, which makes it have completely different operating characteristics from the diode.
Based on silicon single crystal as the basic material of P1N1P2N2 four-layer three-terminal device, started in 1957, because of its characteristics similar to vacuum thyristor, so the international known as silicon thyristor, thyristor T for short, and because the thyristor initially in static rectifier, so also known as silicon controlled rectifier element, referred to as SCR.
In terms of performance, thyristor not only has unidirectional conductivity, but also has more valuable controllability than silicon rectifier element (commonly known as “dead silicon “). It can only be on and off.
Thyristor can control high-power electromechanical equipment with milliampere-level current. If the power exceeds this level, the average current phase allowed through will decrease due to the significant increase in component switching loss. At this time, the nominal current should be degraded.
Thyristor has many advantages, such as: small power control high power, power amplification up to hundreds of thousands of times; The response is very fast, in the microsecond level of opening and closing; No contact operation, no spark, no noise; High efficiency, low cost and so on.
The weakness of thyristor: static and dynamic overload ability is poor; Susceptible to interference and misleading.
Thyristor from the appearance of the main classification: bolt shape, plate shape and bottom shape.
Structure of thyristor element
Regardless of the thyristor’s appearance, their cores are a four-layer P1N1P2N2 structure made up of P-type and N-type silicon. See Figure 1. It has three PN junctions (J1, J2, J3), leading from the P1 layer of the J1 structure to the anode A, from the N2 layer to the negative stage K, from the P2 layer to the control pole G, so it is a four-layer three-terminal semiconductor device.
