摘要:
The invention relates to a device for measuring the volume of a sample, that comprises two cavities formed in a same block, pressure sensors (3, 4) mounted on the block and surrounded by a radiation shield (28) and connected to the sample chamber (1) by curved ducts. A temperature sensor (25) is also added. The apparatus can be used for measuring the volume of radioactive samples by gas expansion in an expansion chamber (2) without the radiations damaging the pressure sensors (3, 4) while allowing for the correction of temperature-rise effects.
