Detaylı Bilgi - Gestra NRG19-51 level electrodes NRG 19-51
The level electrodes NRG 1...-51 are used in conjunction withlevel switch NRS 1-51 as high level alarm for steam boilerplants and (pressurized) hot water installations.A high level alarm prevents the water level from exceeding thepreset max. water level (HW) and for this purpose switchesoff e. g. the feedwater supply.
When the level exceeds the max. water level, the level electrode enters the liquid and an alarm is triggered in the levelswitch NRS 1-51. The switchpoint \"High level (HW) exceeded\"is dictated by the length of the electrode rod.The electrode operation is based on the conductive measuring principle using the electrical conductivity of the water forsignalling water level. The self-monitoring function ensuresthat an alarm will also be triggered if the electrode insulation is contaminated or has developed a leak or if there is amalfunction in the electrical connection.The level electrode is installed inside steam boilers, vessels orinlet lines of hot-water systems. The protection tube providedon site ensures the correct functioning.One level electrode NRG 1...-51 can be installed togetherwith one GESTRA water level limiting electrode in a singleprotection tube or external level pot.If the level electrode is installed in a level pot outside the boiler,make sure that the connecting lines are rinsed regularly. Inaddition, the logic unit SRL is required to monitor the purgingtimes and the purging sequence.If the connecting lines for steam ? 40 mm and water ? 100mm, the installation is considered to be internal. In this casethe rinsing processes do not have to be monitored.
