2. Product Description
2.1. Description of the System
Application The AMU Oxytrace is used to measure low levels of oxygen in
high-purity water. Especially in power plant water cycles (e.g. feed-
water), a very low level of oxygen is needed to prevent corrosion.
Measuring
principle
Clark principle:
The sensor consists of one noble metal electrode (e.g. platinum or
gold), a reference electrode (mostly Ag/AgCl) and optionally a met-
al guard electrode.
The Clark-type electrode is the most widely used oxygen sensor for
measuring oxygen dissolved in a liquid. The basic principle is that
there is a cathode and an anode submersed in an electrolyte and a
voltage is applied between the two parts. Oxygen enters the sensor
through a permeable membrane by diffusion, and is reduced at the
cathode according to
O2 + 4e- + 2 H2O --> 4 OH-
This reaction creates a measurable current. There is a linear cor-
relation between the oxygen concentration and the electrical cur-
rent.
The guard electrode is on the same voltage level as the cathode
but there is no current measurement. Oxygen which diffuses from
the electrolyte to the cathode is consumed by the guard electrode.
As a consequence, residual oxygen in the electrolyte will no more
disturb the measurement signal and the response time to low oxy-
gen levels will be shorter.
Temperature
compensa-
tion
The measuring signal depends on temperature, but is automatically
compensated to 25 °C. The sample temperature is determined con-
tinuously by a temperature sensor inside the oxygen electrode.
Signal
Outputs
Two signal outputs programmable for measured values (freely
scaleable, linear or bilinear) or as continuous control output (control
parameters programmable).
Current loop: 0/4–20 mA
Maximal burden: 510 Ω

AMU Oxytrace
Product Description
Relay 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
Alarm Relay One potential free contact. Summary alarm indication for program-
mable alarm values and Instrument faults.
Available in two configurations:
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 (hold function or re-
mote-off).
Safety
Features
