BURKERT8045型電磁流量變送器,進(jìn)口寶德電磁流量變送器
BURKERT8045型電磁流量變送器的傳統(tǒng)輸出直流電信號有0-5V、0-10V、1-5V、0-20mA、4-20mA等，目前zui廣泛采用的是用4~20mA電流來傳輸模擬量。工業(yè)上zui廣泛采用的是用4~20mA電流來傳輸模擬量。BURKERT采用電流信號的原因是不容易受干擾。并且電流源內(nèi)阻無窮大，導(dǎo)線電阻串聯(lián)在回路中不影響精度，在普通雙絞線上可以傳輸數(shù)百米。上限取20mA是因為防爆的要求：20mA的電流通斷引起的火花能量不足以引燃瓦斯。下限沒有取0mA的原因是為了能檢測斷線：正常工作時不會低于4mA，當(dāng)傳輸線因故障斷路，環(huán)路電流降為0。常取2mA作為斷線報警值。
