Abstract
A heat tone sensor includes a housing with a gas inlet and with a gas outlet as well as a device for generating a gas stream of a gas to be tested between the gas inlet and the gas outlet. A measuring element, around and/or through which the gas stream flows, is configured to catalytically burn at least a portion of the gas stream and to send a measurement signal. The measurement signal indicates a quantity of heat released in the process.
Claims21
A heat tone sensor comprising:
- a housing with a gas inlet and with a gas outlet;
- a device for generating a gas stream, of a gas to be tested, between the gas inlet and the gas outlet;
- and
- a measuring element around or through or both around and through which the gas stream flows, and which is configured to catalytically burn at least a portion of the gas stream and to send a measurement signal, which measurement signal indicates a quantity of heat being released in the catalytic combustion of at least a portion of the gas stream.
A measuring element for a heat tone sensor, the measuring element comprising:
- a jacket with an inlet opening for a gas to be tested and with an outlet opening for the gas being tested;
- and
- a catalytically active material disposed in the jacket in an area between the inlet opening and the outlet opening.
