GESTRA NRS1 559B3B 230V 5VA NRS1-B LEVEL SWITCH PCB

GESTRA NRS1-B is a conductive level control PCB card for Gestra boiler/steam system water level monitoring, rated 230V AC, power consumption 5VA. This level control PCB works with conductive level probes, detects boiler water high/low liquid level and executes safety interlock and alarm logic. This level control PCB monitors probe resistance variation to judge water level, provides relay output for feedwater valve control and boiler emergency shutdown protection. This level control PCB is widely used for steam boiler, marine boiler and industrial steam plant level protection.

This unit is a vital boiler automation spare part for industrial and marine boiler control cabinet overhaul. The boiler automation spare part receives signal from conductive level electrode probes. The boiler automation spare part triggers alarms or safety cut-off when water level exceeds upper/lower safe limits. The boiler automation spare part can replace faulty PCB to restore boiler water level monitoring and safety protection.

It delivers reliable conductive liquid level signal processing for boiler safety systems. The conductive liquid level signal processing processing detects water level via electrode resistance measurement. The conductive liquid level signal processing processing executes mandatory boiler safety protection required by classification and boiler codes. The conductive liquid level signal processing processing prevents dry-running and overfill hazards for steam boiler.

GESTRA NRS1-B PCB is mounted inside boiler control cabinet. It is original Gestra spare part for boiler conductive level monitoring system.
