FMD 02 – CEMS

FMD 02 – CEMS

The continuous measurement of velocity and temperature of gas flows is much important at operation of a system with flowing gases (e.g. hall outlet air, exhaust etc.).

At emission measurements the current concentrations are determined.

For the translation to absolute emitted masses the volume is necessary; this is calculated through the gas velocity.

With the dynamic pressure probe the gas is measured in the exhaust flow. Thereby the differential pressure is continuously measured.

The signal which results from the differential pressure is a degree for the velocity of the exhaust. The microcontroller integrated in the device generates a proportional signal and evaluates the volume flow.

The use of the measuring principle of dynamic pressure and PT100 assures a device which is easy in design and operating as well as the real-time monitoring of the measuring parameters.

The operating and display unit is integrated in the probe head. On the high-quality display all measuring values, status information and parameters are displayed. Furthermore, a real-time display as line diagram is possible.
