Gestra NRG16-36
BRAND : Gestra
Description
The level electrode NRG 16-36 is used in conjunction with level switch NRS 1-50 as water level limiter for steam boilers and (pressurized) hot-water installations and in conjunction with level switches NRS 1-52 / NRS 1-54 or NRS 1-2 / NRS 1-5 as water level controller. Water level limiters switch off the heating when the water level falls below the set minimum level (low water).
Function
The NRG 16-36 is a combination level electrode consisting of 1 electrode tip for low level alarm (LW) and 3 electrode tips for water level control with high level alarm (MAX). The electrode operation is based on the conductive measuring principle using the electrical conductivity of the water for signalling water level. The high integrity self-monitoring function in the level limiter ensures that an alarm will also be triggered if the electrode insulation is contaminated or has developed a leak and/or if there is a malfunction in the electrical connection. The length of the individual electrode rods determines the switchpoints for the respective water levels. The level electrode is installed inside steam boilers, vessels or in an external level pot. If the electrode is installed inside the boiler or vessel, a protection tube provided on side ensures correct functioning. If the level electrode is installed in an isolatable level pot outside the boiler, make sure that the connecting lines are rinsed regularly. In addition, the logic...

The level electrode NRG 16-36 is used in conjunction with level switch NRS 1-50 as water level limiter for steam boilers and (pressurized) hot-water installations and in conjunction with level switches NRS 1-52 / NRS 1-54 or NRS 1-2 / NRS 1-5 as water level controller. Water level limiters switch off the heating when the water level falls below the set minimum level (low water).
Function
The NRG 16-36 is a combination level electrode consisting of
1 electrode tip for low level alarm (LW) and 3 electrode tips
for water level control with high level alarm (MAX).
The electrode operation is based on the conductive measuring principle using the electrical conductivity of the water
for signalling water level. The high integrity self-monitoring
function in the level limiter ensures that an alarm will also
be triggered if the electrode insulation is contaminated or
has developed a leak and/or if there is a malfunction in the
electrical connection.
The length of the individual electrode rods determines the
switchpoints for the respective water levels.
The level electrode is installed inside steam boilers, vessels or
in an external level pot. If the electrode is installed inside the
boiler or vessel, a protection tube provided on side ensures
correct functioning.
If the level electrode is installed in an isolatable level pot
outside the boiler, make sure that the connecting lines are
rinsed regularly. In addition, the logic unit SRL is required to
monitor the purging times and the purging sequence.
If the connecting lines for steam ? 40 mm and water ? 100
mm, the installation is considered to be internal. In this case
the rinsing processes do not have to be monitored.
