Description
The level electrode NRG 211-1 is designed for measuring
the water level in condensate lines. In conjunction with level
switch NRS 2-4 the electrode can be used as max. limit
switch with high level alarm.
Function
The level electrode together with the electronic module NRV
2-30 works according to the capacitance measurement
principle, translating the level changes into level-dependent
current signals.
The electrode is self-monitoring, i. e. a fault in the insulating
seal will cause a malfunction alarm. In addition, a defined
switching signal is given when the fluid reaches 395 °C
because for physical reasons the level cannot be determined
exactly in this temperature range.
The level electrode works with the level switch NRS 2-4
to detect the max. limit and raise a high level alarm. This
equipment combination can be used as part of a controlled
draining system in power plants.
The electrode with welding standpipe is installed in vertical
pipes.
