The LED Tank Display EA01 is de-veloped especially to fit into heavy duty applications in tire engines. It serves as an exact level teleindicator of water and foam tanks.
Principles of Operation
Filling level is indicated by a tricoloured scale of 10 extremely bright LEDs (red/ yellow/green). Intermediate steps are indicated by changements of the resp. highest LED’s brightness. For observers it looks like a nearly continuously lit light-bar.
The LEDs’ brightness is controlled by a photo sensor. It is readable well in bright sunshine and darkness.
This indicator in rugged design is con-structed very compact, water- and dust-proof and résistant to vibration. It fits into indicator panels. The EA01 is designed for operating voltages 12 V to 24 V DC. It is adjusted ex factory as a unitized measuring signal of 0-5 V, 0-10 V or 4-20 mA.

The instrument is protected against voltage reversai and overvoltage.
Controlling of tanks at various places is done easily by connecting the desired amount of EA01 in parallel (only for voltage input).
