德國MiniTest 7400測(cè)厚儀

1、SIDSP® advantages at a glance

• Sensor-Integrated Digital Signal Processing, with this new technology,ElektroPhysik has set a new benchmarkfor innovative coating thickness measurement. High accuracy, unmatched reproducibility, high temperature stability along with an excellent adaptability, these are the main characteristics of SIDSP®.
• Innovative production techniques combined with automatic calibration procedures in which each sensor is calibrated individually allow for highest quality of the MiniTest 7400sensors.
• Take full advantage of the excellent basic sensor characteristics as given by the use of the SIDSP® technology. The unmatched precision during the manufacturing process enable highly identical characteristics for each individual sensor

SIDSP®優(yōu)勢(shì)一覽

• 傳感器集成數(shù)字信號(hào)處理，利用這種新技術(shù)，ElektroPhysik設(shè)定了一個(gè)新的基準(zhǔn)，用于創(chuàng)新涂層厚度測(cè)量。高精度，的重現(xiàn)性，高溫穩(wěn)定性以及出色的適應(yīng)性，這些都是SIDSP®的主要特點(diǎn)。
• 創(chuàng)新的生產(chǎn)技術(shù)結(jié)合自動(dòng)校準(zhǔn)程序，其中每個(gè)傳感器單獨(dú)校準(zhǔn)允許zui高質(zhì)量的MiniTest 7400傳感器。
• 充分利用給出的的基本傳感器特性，通過使用SIDSP®技術(shù)。在制造過程中的的精度使得每個(gè)單獨(dú)的傳感器具有高度相同的特性

2、Reproducibility

• The reliability of readings mainly depends on the reproducibility of readings.
• Electromagnetic disturbances being most commonly the root of error, it is vital to protect the measuring system and sensor cable from such interference.
• Unlike conventional techniques, the SIDSP® sensors create and control the excitation signals for the sensor head inside the sensor. The return signals are directly digitally converted and processed to provide the thickness value. This value is digitall transmitted to the display unit via the sensor cable. In other words: no more interference during signal transmission as is the case with analogue measuring systems. Even if your application requires an extremely longcable – no problem – the increased immunity to interference remains also with long cable extensions.
• ElektroPhysik’s SIDSP® sensors achieve a reproducibility unmatched so far. Place the sensor on the same measuring spot several times and you will obtain exactly the same result – another proof for the high performance of SIDSP® sensors.

重復(fù)性

• 讀數(shù)的可靠性主要取決于讀數(shù)的重現(xiàn)性。
• 電磁干擾zui常見的錯(cuò)誤，保護(hù)測(cè)量系統(tǒng)和傳感器電纜免受此類干擾至關(guān)重要。
• 與傳統(tǒng)技術(shù)不同，SIDSP®傳感器為傳感器內(nèi)部的傳感器頭創(chuàng)建和控制激勵(lì)信號(hào)。返回信號(hào)被直接數(shù)字轉(zhuǎn)換和處理以提供厚度值。該值通過傳感器電纜數(shù)字傳輸?shù)斤@示單元。換句話說：在模擬測(cè)量系統(tǒng)的情況下，在信號(hào)傳輸期間不再有干擾。即使您的應(yīng)用需要非常長(zhǎng)時(shí)間 - 沒有問題 - 增加的抗干擾性仍然存在長(zhǎng)電纜延伸。
• ElektroPhysik的SIDSP®傳感器實(shí)現(xiàn)了迄今為止的再現(xiàn)性。將傳感器放置在同一測(cè)量點(diǎn)上幾次，您將獲得*相同的結(jié)果 - SIDSP®傳感器的高性能的另一個(gè)證明。

3、The manufacturing process

    During the manufacture, the SIDSP® sensors undergo a special calibration procedure at as many as 50 points of the characteristic curve. Given this high number of points, the characteristic curve is most accurate so as to allow to eliminate (inevitable) variations of the sensor head. The calibration data being permanently stored in the sensor, they can be retrieved at any time, no matter which of the SIDSP® display units is connected. In addition, during the manufacturing process, the temperature behaviour of the sensors is permanently determined over the complete range of operating temperature. As a result, each sensor has got its indiviudally adpated temperature compensation allowing to compensate for large variations in temperature and the characteristic curve remaining accurate at any temperature.

制造過程

    在制造過程中，SIDSP®傳感器在特性曲線多達(dá)50個(gè)點(diǎn)進(jìn)行特殊的校準(zhǔn)程序。 給定這么多的點(diǎn)，特征曲線是zui準(zhǔn)確的，以便允許消除（不可避免的）傳感器頭的變化。 校準(zhǔn)數(shù)據(jù)地存儲(chǔ)在傳感器中，它們可以在任何時(shí)間被檢索，而不管哪個(gè)SIDSP®顯示單元被連接。 此外，在制造過程中，在整個(gè)工作溫度范圍內(nèi)地確定傳感器的溫度特性。 結(jié)果，每個(gè)傳感器具有其獨(dú)立的適應(yīng)溫度補(bǔ)償，允許補(bǔ)償溫度的大變化，并且特性曲線在任何溫度下保持性。

4、Sensor flexibility

     Non ferrous metals may vary with respect to their conductivity. Featuring an automatic compensation for such substrate conductivity, the non-ferrous part of the eddy currents based N and FN sensors allow most accurate measurement on a large number of different types of non ferrous metals. Even in case of highly varying substrate conductivities, it is not necessary to recalibrate the sensor. All SIDSP® sensors fully adapt to the geometry of a sample. Equipped with a calibration device for odd shapes,

the sensors can be easily calibrated to your sample. The calibration will be valid over the complete range of your shape/substrate combination once a zero point calibration has

been carried out on an uncoated sample of such shape/substrate combination.

傳感器靈活性

    有色金屬可以根據(jù)其導(dǎo)電性而變化。 具有對(duì)這種襯底電導(dǎo)率的自動(dòng)補(bǔ)償，基于渦流的N和FN傳感器的有色部分允許對(duì)大量不同類型的有色金屬進(jìn)行zui的測(cè)量。 即使在高度變化的襯底電導(dǎo)率的情況下，也不需要重新校準(zhǔn)傳感器。 所有SIDSP®傳感器*適應(yīng)樣品的幾何形狀。 配備奇特形狀的校準(zhǔn)裝置，傳感器可以輕松地根據(jù)您的樣品進(jìn)行校準(zhǔn)。 一旦零點(diǎn)校準(zhǔn)，校準(zhǔn)將在您的形狀/基板組合的整個(gè)范圍內(nèi)有效在這種形狀/基底組合的未涂覆的樣品上進(jìn)行測(cè)量。
