Product Description

Features

  • Uncertainty is up to 0.005%RD;
  • Pressure scale in a range up to 250MPa
  • Built-in thermometer.
  • ± 1.5mm Piston vertical travel.

The model BL516 precision hydraulic deadweight testers are 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.
