過程指示器830 R

採用現場外殼的環路供電數字指示器

環路供電830系列數字指示器可通用於電流測量電路；通過端子輕鬆進行切換（0 … 20 mA或4 … 20 mA）。 可顯示最低0.3 mA電流的測量值。 其壓降低至0.5 V，因此也可用在低負載電壓的電流環路中。

• 已獲准用於HART電路
• 3年保固

Digital loop-powered 830 series indicators are universally useable in current measurement circuits; switching (either 0 … 20 mA or 4 …20 mA) is simply performed via the terminals. The measured value is displayed for a current as low as 0.3 mA. Thanks to the low voltage drop of just 0.5 V, the use in current loops with a low load voltage is also possible.
