In a gas sensor with at least two electrodes and with a sensor body which is connected thereto and is composed of a gas-sensitive material, in addition to pores which may already be present, second cavities are provided in the sensor body. The second cavities may be suitable on account of their size to facilitate and accelerate the distribution of gas molecules in the sensor body and to thus improve the time response of the gas sensor.

Gas sensor and method for its production

An electical current flow sensor, where a spherical surface thereof is subjected to an in-flowing fluid in order to the speed of the fluid. The spherical surface is formed by a body made of a good thermally conductive material. An electrical resistor is disposed in a cavity in the interior of the body of good thermally conductive material. The electrical resistor is placed in a good heat exchange with the wall of the cavity. The electrical resistor is adjusted to a preset temperature by electrical current feed, whereby increased fed-in electrical current is measured and serves as a measure for the current flow speed.
