NRG16-50 Level Probe 1500mm
Gestra NRG16-50 Level Probe 1500mm
The level electrodes NRG 16-50 are used 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 water falls below the low level, the level electrode is exposed, activating a low-level alarm in the level switch NRS 1-50. This switch point, “Low water level (LW)”, is determined by the length of the electrode tip. The electrode operates on the conductive measuring principle using the electrical conductivity of the water for signalling water level.
The self-monitoring function triggers an alarm if the electrode insulation is contaminated, develops a leak and/or if there is a malfunction in the electrical connection.
When installing the level electrode inside steam boilers, vessels, or the inlet lines of hot-water systems, a protection tube provided on-site ensures the function.
One level electrode NRS 1...-50 can be installed alongside one Gestra level electrode, one level switch or transmitter for water level control and a high-level alarm in one single protection tube or level pot.
If the level electrode is installed in a level pot outside the boiler, ensure the connecting lines are cleaned and rinsed regularly. In addition, the logic unit SRL is a requirement to monitor the purging times and the purging sequence.
If the connecting lines for steam ≥ 40mm and water ≥ 100mm, the installation is classed as “inside”, so the purging process does not require monitoring.
