Water level alarm NRG 16-51, NRS 1-51

for overflow detection

Targeted reduction of boiler damage With the water level limiters of the SPECTOR family, GESTRA is now offering the fifth generation of these safety components. The new products provide solutions that conform to the technical literature, increase safety in operation and keep costs down. In accordance with EU boiler standards EN 12952 and EN 12953, in future a risk analysis must be performed for each limiter function, and appropriate Safety Integrity Levels (SIL) established. The boiler protection system must conform at least to SIL 2. FOR THE HIGH LEVEL ALARM: NRG 16-51 AND NRS 1-51 These units are not determined by the technical literature, but by the downstream steam consumers. They assess danger provoked by overfilling or by water carried into downstream parts of the plant. If the potential risk is high, "High Integrity" units are employed. If no immediate damage is expected, "conventional design" units are sufficient.
