Explanatory Notes

System description

The capacitance level probe NRG 211-1 serves as sensor for the level switch

NRS 2-4 (high level) / NRS 2-5 (low level) and can be used as part of a controlled

draining system in power stations or for low level detection in tanks.

Function

The electrode is designed as a rod-type capacitor, the capacitance of which is

electronically compared with a reference capacitance. The result is a level-

proportional measuring voltage. The fluid temperature is measured by an integral

resistance thermometer and electronically compared with a fixed limit. When the

two values are equal in magnitude the level-proportional measuring voltage will

be limited to 4 V.

Design

NRG 211-1

Design with welding standpipe for installation in vertical pipes.
