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.

FEATURE

• 0.005% and 0.01% accuracy
• The accuracy of low limit range keeps same as upper limit range
• Tungsten carbide piston and cylinder
• Motorized piston rotation function
• Built-in thermometer
• Dial indicator shows floating piston positon
• High quality needle valves provide optimum control and sealing
• Optional 280MPa / 40,000 psi is available.
• Optional ISO17025 calibration service

APPLICATION

• Primary pressure calibration in lab
• Precision pressure measurement
