Page 3: Specific Application
AFH-G 3. Specific Application The AFH-G is to be installed only in the specified applications. Every usage which exceeds the specifications is considered to be non-specified. Any dam- ages resulting thereform are not the responsibility of the manufacturer. The user assumes all risk for such usage. - Page 4 Thus, for one individual fibre with a diameter of 3 µm, a short saturation time (several seconds) can be measured. Empirical investigations show that bundled or woven fibres, as are used here in the Kobold sensor, give rise to a longer period prior to saturation. This is because the individual fibres impede each other during water absorption and/or water loss, and the ensuing humidity does not register until later.

In case of damage, please inform your parcel service/ forwarding agent immediately, since they are responsible for damages during transit. Scope of delivery: · Measuring Unit Model “AFH-G” · Operating Instructions 6. Mechanical connection Unavoidable sources of interference should be kept at a good distance from the control systems. - Page 6 The installation position should be chosen so as to prevent condensed water from entering the housing. The preferred installation position is "sensor vertically pointing downwards" or "sensor horizontal". A grommet in the probe prevents penetration of water in the installation positions described above. Wall mounting set Seite 6 AFH-G 07/02...

(this applies to all humidity sensors with hygroscopic measuring elements). Such substances are resin aerosols, lacquer aerosols, smoke depos- its etc. The water-resistant property of the Kobold sensors allows for cleaning using water. Solvents cannot be used for this purpose. A light-duty detergent is recommended. -
