SMA 2000 is especially developed with two independent power sources, main source for 115/230 VAC, and back-up source for 24 VDC as described in rules and regulations.
The system consists of the sensors, magnetic floats with reed switch, and electric cabinet with alarm display unit.
Basic Principle:
Scanjet Independent High Level and Overfill Alarm System is based on magnetic floats moving upward with rising fluid level. The hermetically sealed reed switch is activated by the magnetic float. This signal is connected to an alarm display unit via IS barrier.
