Differential pressure balance / deadweight tester LR-Cal CPB5600-DP

Deadweight Tester / Differential Pressure Balance

Model LR-Cal CPB5600-DP

Differential pressure at real static pressure

Differential Pressure Deadweight Tester (Pressure Balance) for a real calibration of differential pressure under static pressure.
Accuracy (uncertainty) up to ±0.008% or ±0.015% of measured value (plus 0.0001% of the static pressure)


  • Reference instrument for the calibration of differential pressure measuring instruments under static pressure
  • Primary pressure standard for calibration laboratories and factory, for the testing, adjustment and calibration of differential pressure instruments
  • Complete stand-alone system, also suitable for on-site use


  • Measuring range (= static pressure + differential pressure) up to 400 bar pneumatic and up to 1,000 bar hydraulic
  • Total measurement uncertainty to 0.008% of differential pressure plus 1 ppm of static pressure
  • Including factory calibration certificate; DAkkS certificate as option
  • High long-term stability with recommended recalibration cycle every 5 years
  • Masses made from stainless steel and aluminium, can be manufactured to local gravity
