Method of Pressure Measurement Using an Experimental Setup for Investigating a Collection of Thermophysical Properties of Liquids and Gases

摘要

We describe a method of pressure measurement using a Kurant DI-V strain-gage sensor as part of an experimental setup for investigating the isochoric heat capacity and pVT property of liquids and gases. We compared the experimental measurement results with the readings of an MP-600 manometer and data from the National Institute of Standards and Technology (NIST, USA). The efficiency of the use of the indicated strain-gage pressure sensor is shown.
