THE CEM LASER INTERFEROMETER MERCURY MANOBAROMETER

Salustiano Ruiz, Mª. Nieves Medina, Roberto Calvo

Abstract

A laser interferometer mercury manobarometer has been designed and manufactured. It works from 1 kPa up to 130 kPa (gauge, absolute and differential modes) with line pressure up to 500 kPa. The uncertainty budget depends on the range and working mode. In absolute mode the expanded uncertainty ranges from 0.13 Pa up to 0.42 Pa.
