直接測(cè)量或HV-SMARTPROBE™，您的選擇
Vitrek的4700型可直接精密測(cè)量峰值高達(dá)15KV的電壓，開箱即用，無外部探頭。對(duì)于90%的耐壓測(cè)試器和其他高壓源而言，已經(jīng)足夠；但是，如需擴(kuò)大高壓測(cè)量范圍，只需增加一個(gè)或多個(gè)可選用的35KV、70KV和100KV HV-SmartProbes™。Vitrek HV-SmartProbes™可在插入4700型后下載得到的自身校準(zhǔn)數(shù)據(jù)并存儲(chǔ)，從而得到高精準(zhǔn)的校準(zhǔn)后讀數(shù)，而且使任何Vitrek HV-SmartProbe™都能與任何4700型高壓計(jì)配合使用。
HV-SmartProbe’s™*的超低TC衰減器設(shè)計(jì)移除了電壓系數(shù)加法器的使用，同時(shí)，其降低電容結(jié)構(gòu)技術(shù)提高了AC性能。除直接輸入端子外，4700型還有兩個(gè)探頭輸入 - 一個(gè)用于擴(kuò)大測(cè)量范圍的探頭或兩個(gè)進(jìn)行高壓差分測(cè)量的探頭。
性能，設(shè)計(jì)體現(xiàn)
測(cè)量完整性是我們的要求 - 無論是制造高壓醫(yī)療成像設(shè)備的生產(chǎn)線、進(jìn)行突破性研究的實(shí)驗(yàn)室，或是認(rèn)證測(cè)試設(shè)備的校準(zhǔn)實(shí)驗(yàn)室，都必須仔細(xì)挑選工具。為確保的測(cè)量精度，4700型每秒抽取40,000多個(gè)樣點(diǎn)，然后對(duì)這些樣點(diǎn)進(jìn)行過濾、再抽樣、縮放和偏移校正，以提供高達(dá)每秒60個(gè)強(qiáng)化讀數(shù) - 以上所有過程都采用了“*”數(shù)學(xué)算法。True RMS交流電讀數(shù)能被正確讀出，而DC測(cè)量則提供非常穩(wěn)定的超快速處理。除此以外，4700型可提供低至0.01 Hz的VLF AC讀數(shù)，以及波動(dòng)、峰間、波峰因數(shù)和基頻測(cè)量。
高壓測(cè)試自動(dòng)化
憑借4700型內(nèi)置的以太網(wǎng)端口、高速串行通信端口或可用的GPIB，可實(shí)現(xiàn)高壓測(cè)試要求的自動(dòng)化。4700型可*編程，因此可以自行選擇測(cè)量模式和頻寬，然后根據(jù)需要的頻率讀取讀數(shù)。4700型標(biāo)配有USB打印機(jī)端口，以獲取讀數(shù)和打印高壓圖，從而可以記錄下標(biāo)準(zhǔn)耐壓測(cè)試中的驟降或過沖。
特點(diǎn)：
高達(dá)10kV RMS DC的精準(zhǔn)高壓測(cè)量；35kV、70kV和100kV高壓可用 - SmartProbes™
校準(zhǔn)耐壓測(cè)試器、高壓電源和絕緣測(cè)試器
