Differential Pressure Primary Standard

Supplier: WIKA Australia

Designed for use as a differential pressure primary standard, the DH-Budenberg 5500 series can also be used as a high pressure pneumatic standard.

Price Guide: POA

The DH-Budenberg Differential deadweight Tester 5500 is designed specifically for calibration of critically important, high accuracy, differential pressure sensors, at actual working pressures.

DP transmitters, at critical measuring points & higher pressures, should be calibrated at actual line pressures to ensure that pressure expansion of the measuring chamber inaccuracies are minimised.


  • DP Range 2kPa to 78 MPa.
  • Static pressure range to 80 MPa
  • Accuracy up to 0.005% of reading on DP
  • Floating times exceeding 20 minutes up to maximum pressure

The 5500 series are suitable for operation on any gas, including methane and natural gas.
