Disclosed is an IR measuring instrument (1) comprising a least one sensor element (29) which is sensitive to infrared radiation and generates an output signal (12) that depends on the radiation incident on the at least one sensor element (29). The output signal (12) for a predefined incident radiation can be varied by means of an integration time. The actual temperature prevailing on the at least one sensor element (29) is detected and is used for varying the integration time in such a way that the integration time compensates the influence of the temperature variations on the output signal (12) of the at least one sensor element (29).

The invention relates to a thermographic camera comprising at least one infrared radiation detector and at least one adjusting device that supplies control and/or supply voltages required for operating the thermographic camera. In order to design a thermographic camera in which the temperature-induced drift of the electronics can be compensated while the cost of parts is reduced, a storage medium in which at least one temperature-related characteristic curve is stored is provided on the thermographic camera, and the thermographic camera automatically compensates a temperature-induced drift of the at least one adjusting device on the basis of the characteristic curve. The invention further relates to a method for operating such a thermographic camera.

This invention relates to a thermal imaging camera comprising a thermal imaging sensor and a cover plate that can be displaced between an open and a closed position by means of an electric drive. The invention is characterized in that the open and the closed position of the cover plate (1) form respectively self-locking end positions and that an electric drive is provided to switch between the end positions, said drive being supplied with no current in the self-locking end positions.

摘要:
A method for wrapping continuous strands of steel wire about a seismic cable including interconnected sensor sections and conductor sections where a cross sectional diameter of the sensor section is at least four times that of the conductor section. Two layers of armoring are provided with a first layer wrapped in a first angular direction opposite that of the second layer. A stranding assembly is provided which has two selective positions, one for providing a die hole for stranding the conductor section, another for providing a passage hole for allowing the sensor section to pass after wrapping with armor wire.
