ABB 水平型枕式張力計(jì)壓頭非常適用于張力小、軋輥重和運(yùn)行速度高的應(yīng)用，冶金行業(yè)往往有很多這類應(yīng)用。
概覽
ABB 水平型枕式張力計(jì)壓頭有三個(gè)規(guī)格：標(biāo)準(zhǔn)型PFTL 101A/B，通常被用于常規(guī)的金屬處理線。該壓頭適用于軋輥重、張力范圍寬和運(yùn)行速度高的應(yīng)用。
對(duì)于冷軋機(jī)、退火和鍍鋅生產(chǎn)線中有乳化液的帶材張力測(cè)量應(yīng)用，推薦使用軋機(jī)型的PFTL 101AE/BE。PFTL 101AE/BE 壓頭使用固定的連接線纜，防護(hù)等級(jí)達(dá)到IP 66 ，可長(zhǎng)期精確可靠運(yùn)行在有乳化液的應(yīng)用環(huán)境中。所有的ABB 張力計(jì)壓頭交貨時(shí)均進(jìn)行了標(biāo)定。
防酸型PFTL 101AER/BER 壓頭是專為酸洗生產(chǎn)線而設(shè)計(jì)，達(dá)到防護(hù)等級(jí)IP 66/67。
ABB的Millmate 帶材張力測(cè)量系統(tǒng)壓頭，是以1954年獲得專利的、著名的Pressductor?磁致效應(yīng)為基礎(chǔ)的，根據(jù)該原理，鋼材的磁特性會(huì)受到機(jī)械作用力的影響。
在傳感器內(nèi)有四個(gè)孔。相互垂直的兩個(gè)線圈通過這些孔纏繞在一起。一個(gè)線圈被施加交流電，另一個(gè)線圈作為測(cè)量線圈。由于兩個(gè)線圈相互垂直，只要傳感器上沒有負(fù)荷，它們之間就沒有磁耦合。
如果傳感器上有負(fù)荷（如圖所示），磁場(chǎng)特性就會(huì)改變。在受力方向上鋼材的導(dǎo)磁率將降低，在垂直方向上將增加。這導(dǎo)致磁通對(duì)稱性發(fā)生變化，部分磁通將誘導(dǎo)二次側(cè)線圈產(chǎn)生感應(yīng)電壓。感應(yīng)電壓與負(fù)荷成比。
ABB獨(dú)有的壓磁?技術(shù)讓Mini系列枕式壓頭非同尋常的堅(jiān)固，讓它們能承受各種不同的工作條件。

ABB horizontal pillow tensiometer indenters are ideal for applications with low tension, heavy rolls and high running speeds, which are often found in the metallurgical industry.
overview
ABB horizontal pillow tensiometer heads are available in three sizes: Standard PFTL 101A/B, which is commonly used in conventional metal handling lines. The indenter is suitable for applications with heavy rolls, wide tension ranges and high operating speeds.
PFTL 101AE/BE is recommended for strip tension measurement applications with emulsion in cold rolling, annealing and zinc plating lines. The PFTL 101AE/BE indenter uses a fixed connection cable and is protected to IP 66 for accurate and reliable long-term operation in emulsion applications. All ABB tensiometer indenters are calibrated at delivery.
The acid proof PFTL 101AER/BER indenter is designed for pickling lines and is rated IP 66/67.
ABB's Millmate strip tension measuring system indenter is based on the famous Pressductor? magnetic effect, patented in 1954, according to which the magnetic properties of steel are affected by mechanical forces.
There are four holes in the sensor. Two coils perpendicular to each other are wound together through these holes. One coil is applied alternating current and the other coil acts as the measuring coil. Since the two coils are perpendicular to each other, there is no magnetic coupling between them as long as there is no load on the sensor.
If there is a load on the sensor (as shown in the figure), the magnetic field characteristics will change. The magnetic permeability of the steel will decrease in the direction of the force and increase in the vertical direction. This results in a change in the symmetry of the magnetic flux, and part of the magnetic flux will induce induced voltage in the secondary side coil. The induced voltage is proportional to the load.
ABB's unique piezomagnetic ? technology makes the Mini series of pillow indenters exceptionally strong, allowing them to withstand a wide range of operating conditions.
