The VEGASEL 643 is a signal conditioning instrument for level detection and min./max. control for simple control tasks. Typical applications are two-point controls, e.g. pump controls and monitoring functions such as overfill protection and dry run protection.
Advantages
- Simple adjustment of the switching point
- Economical power supply unit and signal conditioning instrument for a 4 … 20 mA sensor
