Intrinsically safe voltage
WebReal-time detection of liquid level in complex environments has always been a knotty issue. In this paper, an intrinsically safe liquid-level sensor system for flammable and explosive environments is designed and implemented. The poly vinyl chloride (PVC) coaxial cable is chosen as the sensing element and the measuring mechanism is analyzed. Then, the … WebNov 16, 2002 · The maximum nonhazardous location voltage, often designated Um, is the maximum voltage that can be applied to each of the non-intrinsically safe terminals of an associated apparatus without affecting intrinsic safety. Generally, this voltage is 250 V, though other values are possible.
