1.3 Field of application
The control unit is used to control the complete FLK Gas Sampling Probe which are mainly used for measuring gas sampling
up to approx. 1800 °C with a high dust content.
Due to the high dust concentration in the process gas, dust deposits in the sampling probe and in the heated filter are
unavoidable. Therefore, automatic, cyclical cleaning has been implemented for the probe and the filter. The mechanical parts
required for this are accommodated in the valve combination. If a compressed air motor is being used for the "emergency
withdrawal" of the probe, the control valves needed for the motor are also in the valve combination.
Note:
See also the general operating manual for the FLK Probe.
