Differential Pressure Primary Standard

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.

Specifications:

• 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.
