Gestra NRG16-52 Level Electrode 4 Tips 1000mm
The Gestra level electrode NRG 16-52 used in conjunction with level switch NRS 1-.. is designed for signalling up to four different water levels and used (for instance) in steam boiler plants and (pressurised) hot-water installations or in condensate and feedwater tanks, e. g. as water level limiter with MIN/MAX alarm.

The level electrode operates in combination with the following level switches: NRS 1-52, NRS 1-53, NRS 1-54 and NRS 1-55 or NRS 1-1, NRS 1-2, NRS 1-3 and NRS 1-5.

The electrode operates on the conductive measuring principle using the electrical conductivity of the water for signalling water level.
The length of the individual electrode rods determines the switch points for the respective water levels.

The level electrode is for installation inside steam boilers, vessels, or within an external level pot. If the Electrodes installation is inside the Boiler or Vessel, a protection tube provided on the side ensures correct functioning.

The Level Electrode NRG 16-52 can operate with one Gestra level electrode for water level limiting or with a high-level alarm in a single protection tube or an external level pot.
