target="_blank"><strong><span style="font-size: 16px;">高斯計</span></strong></a>是檢測磁場磁感應強度的專用儀器，是磁性測量領(lǐng)域中用途最為廣泛的測量儀器之一。可用于測量直流磁場、交流磁場、輻射磁場等各類磁場的磁感應強度。該儀器可以隨身攜帶，量程范圍寬，操作方便，液晶顯示清晰。有峰值保持功能、mT/Gs單位轉(zhuǎn)換、按鍵自動調(diào)零、有兩檔量程相互轉(zhuǎn)換。電源為四節(jié)AA電池。另外還可選配穩(wěn)壓電源，可直接連接市電。<br /> </div><div>　　<strong><span style="font-size: 16px;">高斯計</span></strong>采用的傳感器是基于霍爾效應原理制成的傳感器，即霍爾傳感器。傳感器有橫向、軸向兩種，用戶可根據(jù)需求選擇或另外配置。電路采用低漂移的放大器以及高穩(wěn)定度的供電電源、單片機控制、41⁄2液晶顯示?；魻栃恚簩⒔饘倩虬雽w薄片置于磁場中，當有電流流過時在垂直于電流和磁場的方向上將產(chǎn)生電動勢。<br /> </div><div>　　<strong><span style="font-size: 16px;">高斯計的使用方法</span></strong>：<br /> </div><div>　　1.連接號霍爾頭與儀器<br /> </div><div>　　2.開機：按POWER電源按鈕，接通電源。<br /> </div><div>　　3.按紅色按鈕選擇對應量程。<br /> </div><div>　　4.零點校對：用一字螺絲刀調(diào)節(jié)儀器背部的”調(diào)零“。<br /> </div><div>　　5.磁場測試，單位為毫特斯拉。顯示“-”是則探頭對著N極。<br /> </div><div>　　6.紅色按鈕為量程，按下時為2000mT，否則為200mT。<br /> </div><div>　　7.測量時用霍爾芯片接觸磁鋼表面，測試結(jié)果接近于實際值，用基板面測量，測試結(jié)果偏低。<br /> </div><div>　　除此之外，它的方法校準是將霍爾頭置于標準磁場中，用一字螺絲刀調(diào)節(jié)儀器背部“校準”電位器，知道和標準磁場數(shù)值一致。值得注意的是霍爾頭基板刻度在測量時對著自己，方向垂直于測量平面。</div>
