BL508 Differential Pressure Deadweight Tester (60MPa)

Overview

FEATURES

• Static pressure ranges 0.1MPa to 60MPa;
• Accuracy is 0.01% rdg for single piston, or (2Pa + 5×10-7*P + 1×10-4*△P) for dual pistons
• Traceable to International Standards.
• The piston and cylinder is made of the high intensity, extreme hardness and lowest thermal expansion tungsten carbide
• Piston/cylinder design provides stability and repeatability
• Lowering speed of differential piston is 0.5mm per minute with 5 kg loading
• Sensitivity threshold at zero is 10mg.
• Built in oil-gas separator

APPLICATION

• Primary pressure standards in laboratories
• Precision pressure measurement

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.
