*RoHS 主要為限制電機電子產品之零附件中不得含有鉛、鎘、汞、六價鉻及溴化耐燃劑( PBB 、 PBDE )等物質,在 2006 年 7 月 1 日正式實施。
*輕量化設計約45g重。
*資料檔案為TXT文字檔,格式為逗點分隔符號,可以匯入EXCEL分析或繪圖。
應用範圍:
1.可直接量測4-20mA直流電流。
2.可以接各式輸出標準訊號4-20mA的感測器,並可設定轉換刻度,使輸出即是感測器的正確數據資料。
*Custom Calibration
Select the calibration for your data logger. The data logger will always measure current in the 4 to 20 mA range. If you selected Custom Calibration, then the 4 to 20mA measurement range of the EL-USB-4 will be translated into a graph scale of your own choice, with a unit name of up to 8 characters long (e.g. m/s, gal/min, mA, etc.).
To calibrate the graph scale, you need to match two known input voltages with two corresponding graph output values in the unit that you specified.
For example: You wish to measure flow between 0 and 500 gallons/minute, using a flow transmitter that produces a loop current of 3.2 mA per 100 gal/min.
