Description
Water-level limiter with one level electrode, level monitoring with one level
electrode type NRG 16-38 S
The controller NRS 1-7 is to be used in conjunction with one level electrode
NRG 16 -11 and designed as a self-monitoring water-level limiter featuring
periodic self-checking (SMART) and automatic monitoring of the output relay
contacts. The controller has the following function:
■ Low-level alarm with one switchpoint
The equipment combination detects the min. admissible liquid level (low-level
limiter).
Application in marine steam boilers and (pressurized) hot water installations.
The level transmitter integrated in the level electrode NRGT 26 -1 enables
continuous level monitoring.
Water-level limiter with two level electrodes, level monitoring with one level
