Pressure Test Pumps
- Portable pressure pumps for
generation of pressure and/or vacuum for
pressure comparison measurements (pressure calibration) - Pneumatic models, operated with ambient air
- Hydraulic models, operated with oil or water
- Pressure generation up to 1000 bar (14500 psi),
vacuum generation up to -0.95 bar (-28 inHg)
Pressure Comparison Test Pumps
- Manual generation of test pressure
for test, adjustment and calibration purposes. - Pneumatic hand lever pump (with ambient air), or
- Hydraulic spindle pump (with water or oil, depending on model).
- Make also high pressure values with very low force.
- Fine pressure adjustment with sensitive volume variator.
Deadweight Tester / Pressure Balances
- Primary standard for pressure
- Rigid basements with integrated manual pressure source
- Excellent repeatability
- Uncertainties mathematical calculable
- Mechanical/physical basic principle
- Pneumatic models (with ambient air or nitrogen)
Electronic Pressure Calibrators
- Pressure Calibrators
Pressure reference standard for checking, adjustment and calibration of all kind of pressure reading instruments. - In addition, documenting process calibrators measure mA and V and save calibration data of units under test.
- Some models have data logging functionality.
- Normally, in addition a calibration pressure source is needed (e.g. Pressure Test Pumps or Pressure Comparison Pumps).
Exception: Model LR-Cal LPK 300-PP comes with integrated electric pump -0.8…+20 bar. - Optional the pressure calibrators can be supplied with DAkkS certification.
