Product Description

GESTRA NRG 16-39S

The GESTRA NRG 16-39S is a compact level electrode designed for water level control and limitation in steam boilers, pressurized hot-water installations, as well as condensate and feedwater tanks. It operates based on the conductive measurement principle and is used in conjunction with GESTRA level switches (e.g., NRS 1-.. series) to provide reliable level monitoring and control for various industrial applications. Its robust construction ensures durability in demanding environments, making it suitable for detecting liquid levels in conductive fluids.
