  • Publication number: 20050046838
    Abstract: A process for measuring a point comprising at least one spectrometer and a measuring transducer connected thereto for picking up, processing and forwarding measuring signals from the spectrometer, the spectrometer being arranged in an armature for introduction into a process or a process fluid and the data produced by the spectrometer is used to control a process. The armature comprises a housing for receiving the spectrometer and for securing the armature to a process container containing process fluid and a sensor holder with an inbuilt sensor, interacting with the spectrometer and which is guided in an axially displaceable manner in the armature, whereby the sensor holder protrudes into the process fluid in an extended state.

  • Patent number: 6853195
    Abstract: A symmetrically wired device and a process for measurement of the concentration of ions, especially hydrogen (H+) ions, in a measurement liquid. The device comprises a pH-sensitive measurement electrode, a reference electrode and a comparison electrode, all located in the measurement liquid and which places the measurement liquid at a definable ground reference. The device forms a difference signal referenced to the ground reference from the difference between a measurement signal (?pH) of the measurement electrode and the reference signal (?ref) of the reference electrode. The difference signal is dependent on the ion concentration in the measurement liquid. The device compensates for the noise potential (?chem) arising between the comparison electrode and the measurement electrode by setting a reference potential (?bez) on the comparison electrode, such that ?ref assumes a zero value.

  • Publication number: 20040069619
    Abstract: An automatable measuring, cleaning and calibrating device for pH-electrodes or electrodes for measuring redox potentials, specifically in process engineering, having an electrode armature which keeps the measuring electrode in an operating position or in a maintenance position, whereby the electrode is retained in the maintenance position in a rinsing chamber in which a cleaning and calibration procedure can be performed. The device has a pump device to supply cleaning fluid and calibration solutions to the rinsing chamber over a delivery line connecting the pump device and the rinsing chamber. In order to configure the device more compactly, the pump device includes several feeds on its intake side, and a device is furnished to selectively activate a particular feed, and the media (cleaning fluid, calibration solution, etc.) brought selectively over the particular feeds to the pump device reach the rinsing chamber over the common delivery line.

  • Patent number: 5600434
    Abstract: Craft (11) generally and in particular the transport aircraft (11) which are used for humanitarian purposes and for supplying crisis reaction forces over militarily unknown territory and which have comparatively little manoeuverability are particularly endangered by partisans who operate out of cover with modern portable guided missiles (12), against whose homing heads (13) the flares which were previously discharged from aircraft (11) no longer afford an effective defence. Therefore those and other potentially endangered craft (11) are provided with easily interchangeably and autarchically equipped containers (17) from which the defence beam (16) of a laser source (21) in accordance with pre-guidance by a warning sensor (10), are directed by way of the tracking optical system (19) of a target tracking system (20) on to the approaching guided missile (12) whose homing head (13) is already locked on to heat sources such as for example the engines of the craft (11) to be protected.
