Rain and condensation water can thus drain off. Thisapplies mainly to outdoor mounting as well as installation in areaswhere high humidity is expected (e.g. through cleaning processes) oron cooled or heated vessels.Fig. 3: Measures against moisture ingressThe process fitting must be sealed if there is gauge or low pressure inthe vessel. Before use, check if the seal material is resistant againstthe measured product and the process temperature.The max. permissible pressure is specified in chapter "Technicaldata" or on the type label of the sensor.In the case of instrument housings with self-sealing NPT threads, it isnot possible to have the cable entries screwed in at the factory. Thefree openings for the cable glands are therefore covered with red dustprotection caps as transport protection.Prior to setup you have to replace these protective caps with ap-proved cable glands or close the openings with suitable blind plugs.4.2 Mounting instructionsDue to agitators, equipment vibration or similar, the level switch canbe subjected to strong lateral forces.Suitability for the processconditionsMoisturePressure/VacuumCable entries - NPTthreadAgitators
