Precision hydraulic Deadweight Tester, motorized, (5～250)MPa, 0.005%RD, Sebacate, Tungsten Carbide PCU, 316SS mass set, metric connector with adapters, with temperature indicator
MODEL BL515 HYDRAULIC PRECISION PRESSURE BALANCE
The model BL515 hydraulic precision pressure balance is widely applicable in primary pressure calibration laboratories.
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.
