Application:
The Transmitter AMS 5200 is the control, evaluation- and supply unit for all AMS Flue gas probes. The
transmitter AMS 5200 is in preparation for QAL 1 - certification according European and German
Environmental Regulations.
Measuring principle:
The AMS Flue gas probes are equipped with Zircon dioxide sensors with Platinum electrodes which
are known for their long life expectancy. The Transmitter AMS 5200 supplies the current for the heater
of the Zircon dioxide sensor. To increase the stability of the measuring values AMS regulates the
temperature of the Zircon dioxide sensor within tight limits. The Transmitter AMS 5200 monitors
continuously the Zircon dioxide sensor in the AMS flue gas probes for accuracy and plausibility.
Measuring system:
Typically the Transmitter AMS 5200 is mounted into the GRP housing of the pneumatic unit. The
Transmitter AMS 5200 is mounted into a wall mounting housing with protection class IP 65 for General
applications. For installations in Ex Zone 1 classified areas the Transmitter AMS 5200 is also available
in an Ex-d certified housing.
The Transmitter AMS 5200 could be mounted in an optional pneumatic unit. Due to a 5-wire protected
cable the Transmitter AMS 5200 is connected to the flue gas probe.Via the cable the probe is supplied
with current for the heater of the Zircon dioxide sensor. Another wire transfers the measuring signals
of the probe to the Transmitter AMS 5200 for evaluation. The display of the Transmitter shows the
actual measuring values, the status signals and other important values such as heater current, offset
and possible errors. The oxygen value is provided for further transmission via the potential free
analogue signal port and via the digital RS 232 interface. The other values are available via potential
free contacts. The calibration of the Zircon dioxide sensor in the flue gas probe can be accessed in the
main menu of the Transmitter AMS 5200. During a calibration the analogue signal is “frozen” to the
last valid measuring value. The status signal indicates “maintenance”. For use with the O2 / COe-Flue
gas probe the Transmitter AMS 5200 is available as Twin-Version and provides separate measuring
signals for the components O2 and COe.
