A measurement device ascertains the thermal conductivity of a fluid. The device has a fluid volume holding the fluid, a controller, and a sensor module disposed in the fluid volume. The sensor module has a supporting body and a plurality of sensor wires that extend freely between in each case two contact positions of the supporting body. One of the sensor wires serves as a heat source and is able to be energized for this purpose by the controller. The controller is set up to capture, via at least two of the sensor wires that serve as temperature sensors and are arranged at different distances from the heat source, temperature measurement values that depend on the temperature at the respective temperature sensor, and to ascertain the thermal conductivity in dependence on the temperature measurement values.

Method and measurement device for ascertaining the thermal conductivity of a fluid

A thermal gas sensor for measuring the thermal diffusivity and/or the thermal conductivity of a gas or gas mixture includes a substrate. In the surface of the substrate a trench is formed, as well as at least two conductor structures arranged at a distance from one another on the surface of the substrate. The conductor structures respectively each contain at least two contact sections and a web section connected to the contact sections, the web sections of the conductor structures crossing over the trench at a distance from one another. At least one slot is formed between at least two contact sections of different conductor structures in at least one region of the surface of the substrate.

Device for in-service monitoring of communication transmission equipment

In a method for addressing processor units of an equipment for monitoring and/or controlling, whereby a polling unit and processor units (6) provided with addresses exchange information, the processor units (6) are automatically addressed with the assistance of addressing telegrams in that an address contained in the addressing telegram is respectively incremented. The method can be advantageously used in equipment for in-service monitoring of equipment of communication transmission technology.

A test facility, especially for the seeker or search heads of intelligent guided ammunition, including a target simulator for the reflection of a target signature through the intermediary of antenna elements towards the search head which is mounted on a turntable or rotary member with a flight simulator. Arranged between the target simulator and the search head is a quasi-optical coupling which follows the beam geometry by means of an imaging system and, on the one hand, the search head, as well as, on the other hand, the target simulator are located in or proximate to the applicable focal point of the resultingly produced path of transmission.
