BL508 Differential Pressure Deadweight Tester
|
The model BL508 high static differential pressure deadweight tester ideal primary standard for defining the static pressure up to 60MPa. Both the piston and cylinder are manufactured from tungsten carbide. This pairing of materials, in comparison to other materials, has very low pressure and temperature coefficients of expansion, which results in a very good linearity for the effective area of the piston and a very high accuracy. Over-pressure protection is integrated, which prevents the piston from being forced out vertically and avoids damage to the piston-cylinder system in the event of masses removal under pressure. |

Accuracy |
When use one of two piston gauges, accuracy is 0.01%rdg; When test static pressure, accuracy is (2Pa + 5x10-7*P + 1x10-4*△P), where P= Static Pressure Pa, △P = differential pressure value |
