5.6 0/4-20 mA monitoring
Description
With the aid of an analog module, SIMOCODE pro is capable of measuring
and monitoring further process variables as desired.
For example, the fill level can be monitored to protect a pump against dry
operation, or a differential pressure transducer can be used to monitor the
degree of pollution in a filter. If the fill level undershoots a specified level,
the pump can be switched off and, if a specific differential pressure value is
exceeded, the filter must be cleaned.
