AMU Rescon
Product Description
Input
One input for potential-free contact to freeze the measuring value
or to interrupt control in automated installations (hold function or re
-
mote-off).
Communica
-
tion interface
(optional)
RS232 for logger download with HyperTerminal
RS485 with Fieldbus protocol Modbus or Profibus DP (optional)
Safety
Features
No data loss after power failure. All data is saved in non-volatile
memory.
Over voltage protection of in- and outputs.
Galvanic separation of measuring inputs and signal outputs.
USP
Operating
Mode
The USP Operating Mode implemented in the firmware of the AMU
Rescon transmitter allows the measurement of pharmaceutical wa
-
ter according to the USP <645>.
If the USP Operating Mode is set to <off>, conductivity or resistivity
standard measurement with automatic temperature compensation
is performed.
If the USP Operating Mode ils set to <on>, the temperature com
-
pensation function is disabled. The uncompensated measuring val
-
ues are compared with the values of an implemented table defined
by USP (see table below). If the deviation of the measured values
is too high, the Error 15 (USP Error) is issued.
Conductivity
QC-Kit Test
Plug
The implemented Transmitter Test together with Conductivity QC-
Kit Test Plug containing a traceable high precision resistor allows to
perform a verification of the measuring electronics at any time.
Fluidics
The flow cell QV-Hflow consists of the flow cell block [D], the flow
sensor [B] and the flow regulating valve [E].
