New differential pressure standard at KRISS

S. Woo, I. Choi, H. Song, B. Kim
Abstract:
The accurate measurement of differential pressure at low-line pressure is important in many industrial and commercial activities. The Korea Research Institute of Standards and Science(KRISS) has completed the development of a low differential pressure primary standard covering a range from 1 Pa to 15 kPa for operation with line pressures of 100 kPa. The standard is based on a double pressure balance and includes a test-instrument manifold with pressure controllers. It has a peculiar automatic weight handling mechanism which enables the various weights easily to add or remove from the piston without breaking the reference vacuum during calibration. The performance of the standard has been evaluated using commercial precise differential pressure gauges.
