The Transmitter AMS 3220 is the control, evaluation- and supply unit for all AMS Flue gas probes. In combination with the Transmitter AMS 3220 the AMS Flue gas probes are certified by the German TÜV according European and German environmental regulations and fulfils the requirements for QAL 1 according EN 14181 and EN ISO 14956.

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 3220 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 3220 monitors continuously the Zircon dioxide sensor in the AMS flue gas probes for accuracy and plausibility.

Typically the Transmitter AMS 3220 is mounted into the GRP housing of the pneumatic unit. The Transmitter AMS 3220 is mounted into a wall mounting housing with protection class IP 65 for General applications. For installations in Ex-Zone 1/2 classified areas the Transmitter AMS 3220 is also available in an Ex-d certified housing.

The Transmitter AMS 3220 could be mounted in an optional pneumatic unit. Due to a 6-wire protected cable the Transmitter AMS 3220 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 3220 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 3220. 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 3220 is available as Twin-Version and provides separate measuring signals for the components O2 and Coe.
