Product Description

GESTRA LRR 1-5 Level Electrode

The GESTRA LRR 1-5 is a conductive level electrode designed for monitoring liquid levels in steam boilers and tanks containing conductive fluids. It operates in conjunction with GESTRA level controllers (LRS 1 series) or level limiters (LRS 2 series) to detect minimum or maximum liquid levels reliably. The electrode measures the electrical resistance between the electrode rod(s) and the boiler shell or reference electrode. When the electrode tip is immersed in water, the resistance decreases, triggering the connected controller or limiter. It is suitable for various pressure and temperature ranges depending on the specific model configuration.
