Molecular sieve used for pressurized gas insulation of power switch is connected to sensor for determining degree of saturation of sieve

摘要

A molecular sieve (4) is connected to a sensor for determining the degree of saturation of the sieve. Preferred Features: The sensor is formed as a weighing device (3) supporting the sieve. The sensor is an optical measuring cell having a dye of an indicator material which changes depending on the degree of saturation.
