Miniature gas sensor

PTB-News 3.2017
Especially interesting for

manufacturers of flow sensors

manufacturers of household gas meters

A new miniature gas sensor developed by PTB not only precisely determines the volumetric flow of a gas but also identifies the composition, for example, of several energy gases.

Anordnung der Sensorelemente in der Gassensorik.

For this purpose, it measures the thermal conductivity, temperature conductivity and specific heat of gas volumes of a few milliliters within one tenth of a second. The thermal conductivity is determined by the hot strip method. The temperature conductivity follows from a long-term measurement; the specific heat is measured calorimetrically.
