IFM Electronic SI5007 - 3�3 Operating Principle Temperature Monitoring

5
UK
The hysteresis changes with the flow speed and it is essentially influenced by
the set monitoring range�
It is 2���5 cm/s for the setting 5���100 cm/s (= factory setting), it increases with
higher flow speeds�
• The typical response time of the unit is 1���10 s� It can be influenced by the
switch point:
- Low switch point = quick reaction with rising flow�
- High switch point = quick reaction with falling flow�
3.3 Operating principle temperature monitoring
The unit detects the current medium temperature and switches output OUT2:
