Gestra NRG16-4

BRAND : Gestra

Description

The level electrode NRG 16-4 in conjunction with level switch NRS 1-.. is designed to signal a water level limit and used in steam boiler plants and (pressurized) hot-water installations or in condensate and feedwater tanks, e. g. as water level limiter with MIN/MAX alarm. The level electrode can be used 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.

Function The electrode operation is based on the conductive measuring principle using the electrical conductivity of the water for signalling water level. The length of the electrode rod determines the switchpoint for the water level limit. The level electrode is installed inside steam boilers, vessels or in an external level pot. If the electrode is installed inside the boiler or vessel, a protection tube provided on side ensures correct functioning. The level electrode can be installed together with one GESTRA level electrode for water level limiting or for high-level alarm in a single protection tube or external level pot.
