Fields of application
The dust concentration measuring device PFM 97 is used for the continuous measurement of dust contents, especially for the emission measurement according to TI Air, 13th and 27th BImSchV as well as for the dust concentration measurement in process monitoring. Parallel to the dust measurement flow and temperature of the smoke gas are registered.

Function principle
The special probe of the PFM 97 consists of 2 tribo probes and a dynamic pressure probe: The tribo probes register redundantly the raw signal of the dust concentration. In order to correct the velocity influence at the triboelectric measurement the gas velocity is measured by means of a dynamic pressure probe. The synchronous determination of the gas temperature allows the calculation of the dust concentration in norm state.In case of high dust contents the dynamic pressure probe of the PFM 97 can be cleaned with the PCS 03.

Application and function
For the operation of a facility with streaming gases (e.g. hall exhaust air, exhaust gases etc.) the continuous registration of the exhaust gas velocity respectively the flow as well as the temperature are often of substantial importance. In case of continuous emission measurements the mass of pollutants has to be disclosed additionally (mass flow [kg/h]).
The flow measuring device FMD 99 is a measuring device for the continuous registration of gas velocity and temperature of gas flows in pipelines. Moreover it is possible to display respectively provide the flow in operational or norm state. The use of the dynamic pressure and Pt100-measuring principle guarantees a device simply to install and handle as well as a timely monitoring of the measuring parameters.
The dynamic pressure probe FMD 99 can be cleaned with the probe cleaning system PCS 03 in case of high dust contents.

Fields of application
By means of the gas analyser MGA 23 up to 4 gas components can be measured at the same time: maximum 3 infrared-active gases as e.g. CO, CO2, NO, SO2, CH4 as well as O2 with an electrochemical measuring cell.

Basic versions of the MGA 23 for:

• 1 Infrared-gas component with/without oxygen measurement
• 2 Infrared-gas components with/without oxygen measurement
• 3 Infrared-gas components with/without oxygen measurement

The gas analyser MGA 23 can be used in emission measuring facilities as well as in systems of process and analysis measuring technology.

For measurements of CO, NO, SO2 and O2 according to 13th respectively 27th BlmSchV and TI Air TÜV-approved versions of the MGA 23 are available.

Smallest TÜV-approved and permitted measuring ranges:

• 1- and 2-component-analyser
  • CO2: 0 to 150 mg/m³
  • NO2: 0 to 250 mg/m³
  • SO2: 0 to 400 mg/m³
• 3-component-analyser
  • CO2: 0 to 250 mg/m³
  • NO2: 0 to 400 mg/m³
  • SO2: 0 to 400 mg/m³

All higher measuring ranges are also allowed.

For use in non-potentially explosive atmospheres.

Special configurations:
The MGA 23 with 2 IR-components without pump and with or without oxygen is also available with 2 separate gas ways. This allows the measurement of 2 measuring points or e.g. at the NOx-measurement the state before and after converter.

Tasks
Due to the increasing sensitiveness of the people odour nuisances from industry, agriculture and waste recycling are tolerated less and less. By means of the odour measuring device OMD 98 the possibility is given to record odour concentrations under industrial conditions continuously. Between the output signals of the sensors and the odour concentrations a functional correlation can be determined by olfactory calibration. As result a continuous statement of the odour concentration as well as a statement of the kind of odour is possible.
The OMD 98 consists of single modules constructed as 19''-rack and allows on this way the adjustment to different applications. The basic modul consists of 2 sensor chambers, the control unit and an automatic pre-dilution. As output a serial interface as well as 2 standardised and freely programmable analogue outputs are available. In addition digital inputs and outputs are offered. The recording of measuring signals can be done on PC with a special software (including automatic pattern identification) as well as with any kind of measuring value recording or a process control system.
