Gestra NRG19-50 L=100mm G3/4 PN160 Conductive Level Electrode (NRG19 Series)

• Manufacturer: GESTRA
• Model / MPN: NRG19-50
• Electrode Length (L): 100 mm (determines the low-water switchpoint)
• Mechanical Connection: G ¾ A threaded connection (ISO 228-1)
• Pressure Rating: PN 160 (Nominal pressure capability)
• Max Service Pressure: 100 bar at a temperature of 311 °C
• Measuring Principle: Conductive (utilizes the electrical conductivity of water)
• Body Material: High-grade stainless steel
• Boiler Protection: When the water level drops below the tip of the 100mm electrode, it triggers an instant low-water alarm (LW), cutting power to the boiler heating elements to prevent catastrophic dry-firing damage.
• Self-Monitoring Safety: The system features advanced internal diagnostics. It triggers a safety alarm automatically if the electrode insulation degrades, develops a leak, or suffers an electrical connection failure.
• Installation Requirements: It can be mounted inside a boiler vessel or within an external level pot/standpipe. Per GESTRA Installation Manuals, you cannot install two NRG19-50 limiters inside the same single standpipe.
