三、制造商：德國ZAPPITEC

    中國總代：青島浩正科儀智能技術(shù)有限公司

四、儀器介紹

ZAPPITEC mod.12Z利用最新的技術(shù)進(jìn)步提供一種不需要特殊培訓(xùn)的設(shè)備，可以對(duì)非鐵磁性金屬的電導(dǎo)率進(jìn)行非破壞性，快速和精確的測量，尤其是用于輸變電設(shè)備金屬監(jiān)督項(xiàng)目中銅排導(dǎo)電率測試，用于熔斷器導(dǎo)電片電導(dǎo)率的測試。

The Portable Eddy Current Conductivity Meter ZAPPITEC mod. 12Z takes advantage of thelatest technological advances to provide an equipment that does not require special training，allowing non-destructive, quick and precise measurements of electrical conductivity innon-ferromagnetic metals.

五、儀器特點(diǎn)

電導(dǎo)率測量是以非破壞性方式檢查金屬純度的非常寶貴的工具。

它還用于根據(jù)其導(dǎo)電性或熱處理對(duì)不同的合金進(jìn)行分類，并且也可在航空航天系統(tǒng)監(jiān)測鋁合金在許多應(yīng)用中的熱處理和熱損傷，它也可以用來評(píng)估金屬和合金的熱導(dǎo)率。Conductivity measurements are an invaluable tool to check in a nondestructive way the purityof metals. It is also used to sort different alloys according to its conductivity or heat treatmentand to monitor heat treatment and heat damage in aerospace aluminium alloys among manyother applications. It can also be used to evaluate thermal conductivity in metals and alloys.

Conductivity of selected pure metals

The Conductivity Meter model 12Z has two context-sensitive buttons and a high resolution LCDdisplay. The function of each button is shown in the lower part of the display. When notmeasuring conductivity the display shows the temperature of the probe in °C.

12Z有兩個(gè)上下相關(guān)按鈕和一個(gè)高分辨率LCD顯示器。每個(gè)按鈕的功能顯示在顯示屏的下部。當(dāng)不測量電導(dǎo)率時(shí)，顯示屏?xí)��?span>°C顯示探頭的溫度。

The leftmost button turns the instrument on and off and the central button performs Calibration( Cal ).最左邊的按鈕打開和關(guān)閉儀器，中央按鈕執(zhí)行校準(zhǔn)（Cal）。

六、儀器功能

The model 12Z has the following special features:

12Z具有以下特殊功能：

?Automatic 1 point Calibration自動(dòng)1鍵校準(zhǔn)

The conductivity values of standards shipped with the instrument are recorded initsnon-volatile memory. To calibrate, just place the sensor against the standardand press "Cal". The 12Z will now be calibrated around that conductivity value.The instrument can only be calibrated with the standards supplied with the unit.

儀器附帶的標(biāo)準(zhǔn)電導(dǎo)率值記錄在非易失性存儲(chǔ)器中。要進(jìn)行校準(zhǔn)，只需將傳感器對(duì)準(zhǔn)標(biāo)準(zhǔn)并按下“Cal”即可�，F(xiàn)在12Z將在該電導(dǎo)率值附近進(jìn)行校準(zhǔn)。

?Lift-off compensation and measurement提升補(bǔ)償和測量

The 12Z provides the user with lift-off measurements which can be used toevaluate coating thickness or surface condition. It allows to accurately measureconductivity even in rough "as-cast" surfaces.

12Z為用戶提供剝離測量，可用于評(píng)估涂層厚度或表面狀況。即使在粗糙的“鑄造”表面，它也可以準(zhǔn)確測量電導(dǎo)率。

?Low power operation低功耗操作

The unit is powered by four "AA" alkaline batteries which provide around 100hours of continuous measurement. The auto-shut-off system extends battery lifeby turning off the unit if it is not being used. Replace all four batteries immediatelywhen the battery indicator shows an empty battery.

本裝置由四節(jié)“AA”堿性電池供電，可提供大約100小時(shí)的連續(xù)測量。自動(dòng)關(guān)閉系統(tǒng)通過關(guān)閉設(shè)備來延長電池的使用壽命。電池指示燈顯示空電池時(shí)立即更換所有四塊電池。

七、儀器工作原理

Principle of operation  工作原理

12Z傳感器產(chǎn)生一個(gè)高頻磁場（60kHz），它在要測試的大部分樣品中感應(yīng)出渦流。傳感器和樣品之間不需要接觸，可以進(jìn)行真正的非接觸式測量。這樣可以通過非導(dǎo)電涂料（如油漆或表面氧化物）進(jìn)行精確測量。

A high-frequency magnetic field (60kHz) is generated by the 12Z sensor which induces eddy currents in the bulk of the sample to be tested. There is no need of contact between the sensor and the sample, allowing true non-contact measurement. This allows precise measurements through non conductive coatings such as paints or surface oxides.
