深圳灣邊貿(mào)易代理美國Altek 334A毫安回路校準(zhǔn)儀

產(chǎn)品說明:

可從任意預(yù)定位置來凋節(jié)輸出值

•采用數(shù)字電位器調(diào)值簡化操作

•具有校驗所有回路4 -20毫安的功能

•產(chǎn)生0.00-24.00毫安或4-20毫安量程的-25.0 ~125.0%信號

•可測量到52.00毫安

•提供兩線制回路電源至27V

•連接回路電源為3~45 V直流電壓

•測量回路電源直流電壓

•快速輸出三個任意設(shè)定的中間值

Altek334A毫安回路校準(zhǔn)儀專門用來測量和校驗回路。具有4-20毫安信號所有的回路校準(zhǔn)功能，可作為mA表及兩線制24mA直流模擬信號器并且能測量回路電源電壓，是一個多功能回路校準(zhǔn)儀，可以直接輸出毫安值，也可以以4-20mA的百分比形式輸出。

Altek334A毫安回路校準(zhǔn)儀為兩線制變送器供電的同時可顯示電流。當(dāng)作為過程控制用的變送器拆去修理時，可簡便地用Altek334A毫安回路校準(zhǔn)儀代替控制器，用手動調(diào)節(jié)進(jìn)行控制。

334A毫安回路校準(zhǔn)儀出廠標(biāo)配﹕安裝固定的測試筆、9V電池及說明書
