1. Product Description
1.1. Description of the System
This instrument is applicable for the measurement of conductivity in
high purity water applications.
The AMU Powercon measures the specific (total) conductivity or
the acid (cation) conductivity of a sample. For the measurement of
the acid conductivity a cation exchanger bottle is necessary. The
transmitter can be used with a two-electrode conductivity sensor
with an integrated Pt1000 temperature sensor, e.g. Swansensor
UP-Con1000.
Application
Range
The conductivity is a parameter for the total quantity of ions present
in the solution. It can be used for the controlling of:
the condition of waters
water purification
water hardness
completeness of ion analysis
Special
Features
Many temperature compensation curves for specific conductivity
measurement:
none
Coefficient
Neutral salts
High-purity water
Strong acids
Strong bases
Ammonia, Eth. am.
Morpholine
Signal
Outputs
Two signal outputs programmable for measured values (freely scal-
able, linear, bilinear, log) or as continuous control output (control
parameters programmable).
Current loop: 0/4–20 mA
Maximal burden: 510 Ω
Relays Two potential-free contacts programmable as limit switches for
measuring values, controllers or timer for system cleaning with au-
tomatic hold function.
Maximum load: 100 mA/50 V

Product Description
Alarm Relay One potential free contact. Summary alarm indication for program-
mable alarm values and Instrument faults.

Normally open*: Closed during normal operation, open in case of
error or power loss.
Normally closed: Open during normal operation, closed in case
of error or power loss
*Standard configuration. To order the version with normally closed
alarm relay, contact your dealer in advance.
Maximum load: 100 mA/50 V
Input One input for potential-free contact to freeze the measuring value
or to interrupt control in automated installations. Programmable as
HOLD or OFF function.
Communica-
tion interface
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.
Measuring
principle
When a voltage is set between two electrodes in an electrolyte
solution, the result is an electric field which exerts force on the
charged ions: the positively charged cations move towards the neg-
ative electrode (cathode) and the negatively charged anions to-
wards the positive electrode (anode). The ions, by way of capture
or release of electrons at the electrodes, are discharged and so a
current I flows through this cycle and the Ohms law V = I×R ap-
plies. From the total resistance R of the current loop, only the resis-
tance of the electrolyte solution, respectively its conductivity 1/R, is
of interest.
The cell constant of the sensor is determined by the manufacturer
and is printed on the sensor label. If the cell constant has been pro-
grammed in the transmitter, the instrument measures correctly.
Measuring unit is S/cm or S/m.
Specific
Conductivity
Conductivity from all ions in the sample, mainly the alkalization
agent. The contribution of impurities is masked by the alkalization
agent.
Cation Con-
ductivity (Acid
Conductivity):
The alkalization agent is removed in the cation column. All cationic
ions are exchanged with H+, all anionic impurities (ions with nega-
tive charge) pass through the column unchanged.

AMU Powercon
Product Description
A-96.250.331 / 230320 5
Temperature
compensation
The mobility of ions in water increases with higher temperature,
which enlarges the conductivity. Therefore, the temperature is mea-
sured simultaneously by an integrated Pt1000 temperature sensor
and the conductivity is compensated to 25 °C. Several temperature
compensation curves, designed for different water compositions,
can be chosen.
After cation exchanger (cation conductivity), the temperature com-
pensation curve strong acids has to be set.
For more information see: Wagner, Heinz: Influence of Tempera-
ture on Electrical Conductivity of Diluted Aqueous Solutions,
PowerPlant Chemistry 2012, 14(7), 455-469.
Standard
Temperature
The displayed conductivity value is compensated to 25 °C standard
temperature.
