Compact flow controllers for pressurized micro flows
Gettorf - Sensor expert EGE expands its range of inline flow controllers by two new models featuring robust process connections.
Gettorf – Sensor expert EGE expands its range of inline flow
controllers by two new models featuring robust process connections. Both new
types are highly resistant to aggressive media and provide fast reaction times.
The SDN 503 model detects flows between 1 and 200 ml/min and withstands pressure
up to 10 bar. The SDN 504 DYN model is suitable for micro flow pulses from
0.02 ml/min onwards and pressures up to 20 bar. The sensor ensures e.g. the
accurate lubrication of metal sheets before stamping or the minimal lubrication
of bearings. Measured values are continuously monitored by internal electronics
which also generate a switching signal should the flow pulses discontinue. The
dwell time can be adjusted in a 0.5...10 s range. Moreover, an integrated LED
display shows the current flow status.
Both units are fitted into pipes via a
tube fitting or a G¼ thread. Due to their compact design, the sensors require
little space: for parallel monitoring, several flow controllers can easily be
mounted alongside each other. Based on the thermodynamic principle, they ensure
wear-free and reliable operation.
