Compact System for Level Monitoring
NRGS 11-2
NRGS 16-2
Description
The NRGS 11-2, NRGS 16-2 is a compact-type system
consisting of a level electrode with four tips and an integrated
level switching controller.
The compact system is used as water level controller / limiter,
for instance in steam boilers, (pressurized) hot-water installations as well as condensate and feedwater collecting tanks. Function
For the correct functioning of the equipment the water must
have a minimum conductivity of > 0.5 µS/cm at 25 °C.
The length of the individual electrode tips determines the
switchpoints for water level control and MIN level.
The equipment monitors the water level by sensing whether
the electrode tips are exposed or immersed and – by energizing or de-energizing the controller output contact – switches
the feedwater pump on or off. The LED for pump is illuminated
when the feedwater pump is switched on by the equipment.
When the water level falls below the low level, the two MIN
electrode tips are exposed and the equipment energises
the MIN output contacts after the de-energizing delay has
elapsed. The safety circuit for the heating will be opened and
the two MIN LED are illuminated.
A MIN alarm can be simulated by pressing the test button.
The heating will be switched off and interlocked. To reset the
interlock the MIN electrode tips must enter the water again
and the button “Reset” must be pushed.
