NRG16-51 Level Probe 1500mm
Gestra NRG16-51 Level Probe 1500mm
The level electrodes NRG 16-51 are used in conjunction with level switch NRS 1-51 as high water level alarms for steam boiler plants and (pressurized) hot water installations. A high-level Alarm prevents the water level from exceeding the preset maximum water level (HW) and switches off (for example) the feedwater supply.
When the water level exceeds the maximum, the level electrode enters the liquid and triggers an alarm in the level switch NRS 1-51. The switchpoint “High level (HW) exceeded” is dictated by the length of the electrode rod.
The electrode operates on a 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, develops a leak, or if there is a malfunction in the electrical connection.
The level electrode is for installation inside steam boilers, vessels or inlet lines of hot-water systems. The protective tube mounted on-site will ensure correct functioning. One level electrode NRG 1...-51 can be installed with one Gestra water level limiting electrode in a single protection tube or an external 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.
When the connecting lines for steam are ≥ 40mm, and water is ≥ 100mm the Level Probe installation is considered internal. The rinsing processes do not require monitoring if this is the case.
