Description
The level electrode NRG 16-11 S is used in conjunction with
level switch NRS 1-50 (de-energizing delay: 15 seconds)
as water-level limiter for steam boilers and (pressurized)
hot-water installations on board of seagoing vessels, mobile
offshore platforms or river boats. Water level limiters switch
off the heating when the water level falls below the set
minimum level (low water).
