Page 9: Mounting
Fig. 2: Measures against moisture penetration Transport Do not hold EL 4 on its electrode rods. Particularly with long rod versions, the sensor can be damaged by the weight of the instrument. Pressure/Vacuum The process fitting must be sealed if there is gauge or low pressure in the vessel. - Page 10 Inflowing medium If EL 4 is mounted in the filling stream, unwanted false measurement signals can be generated. For this reason, mount EL 4 at a position in the vessel where no disturbances, e.g. from filling openings, agitators, etc., can occur.
- Page 11 Use conductive seals, such as those made of copper or lead, etc. Insulating measures, such as covering the thread with Teflon tape, can interrupt the necessary electrical connection with metal vessels. For this reason, ground the probe on the vessel or use a conductive seal material. Conductive probe EL 4...
