The level electrodes NRG 1...-50 are used in conjunction with level switch NRS 1-50 as water level limiters for steam boiler plants and (pressurised) hot water installations. Water level limiters switch off the heating when the water level falls below the set minimum level (low water). When the water level falls below the low level, the level electrode is exposed and a low level alarm is triggered in the level switch NRS 1-50. This switchpoint “Low water level (LW)” is determined by the length of the electrode tip. The electrode operation is based on the conductive measuring principle using the electrical conductivity of the water for signalling water level. The self-monitoring function ensures that an alarm will also be triggered if the electrode insulation is contaminated or has developed a leak and/or if there is a malfunction in the electrical connection. The level electrode is installed inside steam boilers, vessels or inlet lines of hot-water systems. The protection tube provided on site ensures the function. One level electrode NRS 1...-50 can be installed together with one GESTRA level electrode, one level switch or transmitter for water level control and low level alarm in one single protection tube or level pot. If the level electrode is installed in a level pot outside the boiler, make sure that the connecting lines are rinsed regularly. In addition, the logic unit SRL is required to monitor the purging times and the purging sequence.

Maintenance method of refrigerator compressor without stopping
Maintenance method of refrigerator compressor without stopping The focus of non-stop compressor maintenance is on the cooling effect. If the cooling effect is normal without stopping, the fault is in the thermostat. Otherwise, it is because the system lacks fluorine and the temperature falls below the control point, which results in non-stop. When repairing,
