Prosonic S FMU90
8 Endress + Hauser
Input
Sensor inputs Depending on the instrument version, 1 or 2 of the sensors FDU91, FDU91F, FDU92, FDU93, FDU95 and
FDU96 can be connected. The Prosonic S identifies these sensors automatically.
In order to support existing installations, the sensors of the former series FDU8x can be connected as well. The
type of sensor must be entered manually.
#
Warning!
The sensors FDU83, FDU84, FDU85 and FDU86 with an ATEX, FM or CSA certificate are not certified for
connection to the transmitter FMU90.
External limit switches
(option)
Optionally, the Prosonic S FMU90 has four inputs for external limit switches (FMU90-********B***).
Switching options
• external passive limit switch (NC/NO switch)
• 0: < 8 V; 1: > 16 V
Usage (examples)
• pump feedback (for FMU90-*3******B***) and FMU90-*4******B***)
• pump tariff control (for FMU90-*3******B***) and FMU90-*4******B***)
• start/stop/reset of daily counters (for flow measurements)
(for FMU90-*2******B*** and FMU90-*4******B***)
• min/max level detection, e.g. by Liquiphant
External temperature sensor Optionally, the Prosonic S FMU90 has an input for an external temperature sensor (FMU90-********B***).
Connectable sensors
• Pt100 (3-wire or 4-wire connection)
A Pt100 with 2-wire connection may not be used due to its insufficient accuracy.
• FMT131(from Endress+Hauser, see chapter "Accessories")
Usage (example)
• Time-of-flight correction for a heated sensor (FDU91-***B*).
