Level device NVG 200
1. General
1.1 Description measuring principle
The NVG 200 level device is used for conductive level monitoring in electrically con-
ductive liquids. A simple level control can be implemented on channel 1 using a min.
and max. electrode. A pump or valve can be controlled directly via a potential-free
changeover contact. A switching time delay of 0.5 to 10 seconds can be set. Chan-
nel 2 works independently of the first and can be used either as an additional full or
empty detector. For example, overfill protection or dry-running protection can be
implemented.
- Compact design (top-hat rail mounting, 22.5mm width)
- 2 separate functional channels
- 2 potential-free changers
- Adjustable sensitivity range (1...100 k)
- Adjustable switching time delay (0.5...10 sec)
- Direct voltage-free electrode voltage
