Checker的理論操作Theory of operation：
當高頻率的脈沖由超聲波傳感器產(chǎn)生的固體進入層壓復合片結(jié)合，它將穿越材料，直到它遇到空中邊界，此時它反映了早在一個可以檢測回聲一計。 在固體材料的結(jié)構(gòu)情況下，這種思考將來自后墻或?qū)訅喊宓膬?nèi)表面。但是，如果有一個分層開裂或地下平行于表面，然后反射會，而不是從損壞的地區(qū)，在較早的時間到達。從良好的損壞材料與回聲模式差異可以用來確定內(nèi)部損害，不從表面明顯的領(lǐng)域。默認警報示范35RDC設(shè)置將響應(yīng)分層的復合材料的名義內(nèi)發(fā)生兩層厚度從后墻緩沖區(qū)，以適應(yīng)變化的速度，輕微的厚度變化，或簾布下降。

Checker檢測儀程序：
35RDC型超聲波缺陷檢測儀計必須先校準具體的材料厚度是進行測試。 用戶通常標識的范疇，這表明撞擊損壞，然后移動到一個點五點57分英寸（75150毫米）離開這個地方的一個領(lǐng)域，似乎是干凈的。超聲換能器的耦合到已知良好的物質(zhì)領(lǐng)域和經(jīng)營者按一個校準的關(guān)鍵。該指數(shù)確定從背面的后墻回聲綜合的校準點，并建立一個參考。 該指數(shù)然后切換可移動傳感器對涉嫌區(qū)把測試模式和用戶。當傳感器耦合到一個測試點，測量比較新的回聲模式的參考模式。如果收到的回聲早于后墻回聲，或后墻回聲不存在，這說明可能損害與評估顯示跡象“壞”。如果收到的回聲早于校準后墻回聲窗口，或者如果后墻回聲不存在，這說明可能損害與評估顯示跡象“壞”。如果只有一個強大的后墻上內(nèi)收到回音校準窗口，然后在測量標志顯示“好。”如果只有一個強大的后墻上收到回音，但它超越了校準窗口的，則計顯示加州以外的厚度顯示為“。”由于這種分析是在參考回波的基礎(chǔ)上，35RDC型超聲波缺陷檢測儀必須始終重新調(diào)整時，切換到一個不同厚度的或不同的材料領(lǐng)域。 這個校準過程，通常只需幾秒鐘。如果試圖重新調(diào)整衡量的情況下不同厚度的材料，該指數(shù)將顯示或者“不好”或“超越卡爾厚度”這取決于新材料薄或厚，比用于校準。重要的是要注意，“壞”應(yīng)該調(diào)查表明由訓練有素的專業(yè)人員進一步誰是熟悉綜合檢查。 與模型35RDC型超聲波缺陷檢測儀計測試是的，并不等于由訓練有素的督察，以**的測試，初步篩選

Checker panametrics 35RDC概述：
The handheld 35RDC
is a simple Go/No-Go ultrasonic instrument designed to detect subsurface
defects caused by impact damage on solid laminate aircraft composite
structures. The 35RDC features a backlit LCD that displays the word GOOD if no
subsurface damage is found or the word BAD when it detects subsurface damage.
It uses an ultrasonic transducer that can be placed or scanned on the area of
composite material suspected of having impact damage. Weighing only 0.24 Kg
(8.5 oz.) and featuring a simplified keypad, this rugged ultrasonic instrument
is easy to operate and requires minimal training.
