The Gestra ERL 16-1 is a robust level electrode designed for reliable level detection in conductive liquids. It is primarily used to provide high or low-level alarms in steam boilers, condensate tanks, and feedwater tanks, ensuring operational safety and preventing damage from extreme water levels. Built for demanding industrial environments, the ERL 16-1 operates effectively under high pressure and temperature conditions. This electrode functions based on the conductive principle and is used in conjunction with Gestra level controllers (such as NRS 1-50, NRS 1-51) to create a complete and certified safety alarm system.
