✦ Synopsis
We have developed and calibrated an accurate pressure gauge studying the flow of liquid or gaseous helium. The gauge is designed to make measurements of pressure drops in liquid helium flow experiments but could be used for a broad range of other purposes. The gauge is calibrated over a range of pressures from 0 to 200 Pa and can resolve pressures as small as 0.01 Pa. It is accurate to better than 0.5% of the reading or ± 0.01 Pa, whichever is greater, and maintains this accuracy even after warm up and cool down.
