Gettorf – Sensor expert EGE extends the SDN 552 series of flow
controllers for various media, adding a new model with a wide application range
which features a digital display. Just like in predecessor models,
characteristics for water-glycol mixtures are pre-programmed in the new sensor.
Additionally, characteristics for other media, such as emulsions, cooling
liquids or lubricants can be freely programmed. Since programmed values can be
read out and transferred to other sensors, only one programming process is
required for multiple units. In addition to the flow rate, the medium
temperature can be detected: an analog output delivers the corresponding signal.
The sensors come with an integrated digital display which shows the current
flow rate. They operate according to the thermodynamic principle and have no
moving parts which protrude into the medium.
The devices are fitted directly
into pipes via tube fittings. They are available with flow rates ranging between
1 and 40 l/min. Within those limits, two switching points may be programmed as
NC and NO contacts. Hysteresis and time delay can also be set to match the
application. Sensors with a switching point and an additional linear 4..20 mA
current output are available for control purposes and logging.
