Sample Gas Probes

                         

 

Either in environmental related gas analysis like  stack testing, continuous emission monitoring (CEM), vehicle emission testing or LEL warning indication and in process applications like combustion efficiency monitoring, boiler trim, ethylene plants or petro chemistry, sample gas needs to be extracted from the gas stream.

It is obvious, that for a reliable analysis the sample gas must be extracted free of ambient gas leaking into the system and at the same time the dew point of the sample must remain stable.

 

This explains why the sample gas probe is the important interface between the process and the analyser system.

Quality, reliability and low operation cost have been the main targets for the development of this programme. The results are outstanding: the modular design allows application specific combinations in a very price effective manner.

The GAS 222 series of sample probes provides "down to earth" solutions based on advanced modular designs.Depending on the application, a variaty of heated or unheated basis units can be combined with in-situ or downstream filters. The filter material can be chosen from sintered ceramic to sintered stainless steel or even pleated stainless steel. Filters with large surfaces provide long life time. For the in-situ filters a highly efficient blowback system is available at reasonable cost.

The ECO series covers a broad range of applications with high dust loads but do not require heating. The directly attached blowback devices plus a variaty of filter elements with large surface areas are the features of these probes.

The APO series provides professional material for simple applications.

 

Bühler sample gas probes are the best solutions if cost effective installation and low operational cost are a concern!

 

 

How to use the probe finder

Use application parameters like process temperature, dust load and ambient conditions for orientation and follow with cursor on a potential version of probe. By hitting a type no. a window will open showing scheme and brief facts. The respective data sheet will open upon mouseclick.
