Measuring Ranges, Filling Fluids Overload Limits Filling Fluids Note: All Ringbalance instruments are factory-filled. The type of oil need not be mentioned in the order. "Mineral Oil" density 0,8 kg/l; for ranges up to +/-700 Pa max. overload: +/-900 Pa Overload Protection Every Ringbalance is inherently protected to at least +/-900 Pa (3.5"W.C.), even it has, for example, a measuring range of only 0-40 Pa (0.15"W.C.). With the synthetic oil filling fluid, the Ringbalance is inherently protected to +/-2.1 kPa (8"W.C.). If those limits (900 Pa / 2.1 kPa) are expected to be exceeded in the...
