Detail
VIRA D-SK 2000 is a new-generation on-off level control and alarm system for steam boilers. The system controls the feedwater pump according to boiler-water level and provides high and low level alarm functions for reliable boiler operation.
Conductivity-Type Level Measurement
The system uses the SD 2400 conductivity-type level probe to detect defined boiler-water levels. The controller starts the feedwater pump at the low level and stops it when the required high level is reached, supporting controlled boiler-water management.
Modern Controller Design
The D-SK 2400 controller operates with a 24VDC supply and is available in DIN-rail and panel-mount versions. Its modern design supports flexible integration into boiler control panels and new equipment designs.
Clear Indication and Operator Functions
A 7-segment display provides clear local status indication. Dedicated test and reset buttons support operator checks and controlled intervention, while the automatic latching function supports the required alarm response during operation.
Integrated Control and Alarm Functions
D-SK 2000 combines on-off feedwater pump control with high and low water-level alarm functions in one system. This approach supports practical installation, monitoring and operation in steam boiler applications.
