Sample Probes by Bühler Technologies
Sample gas probes form a critical point between process and analysis system. They extract sample gas from the process stream and supply it to the analysis system. They should already remove undesirable particulates at the sampling point and avoid cold spots thus preventing false measurements. Our probes are easy to maintain without requiring a lot of tools. Their designs are suitable for critical ambient conditions such as explosive areas and provide weather protection.

In many applications gas analysis is key for safe and efficient control of process flows, environmental protection and quality assurance. In extractive gas analysis the location of the gas sampling point is crucial for the reproducibility and accuracy of the analysis results.
The specific filter capacity, corrosion resistance and functional equipment requirements for the probe arise from the composition of the sample gas. However, operating costs are also an important criterion in the selection, as the sampling points are frequently located at hard to access points in the system. Effective particle filter backwashing options and low maintenance characterize the extensive GAS probe series.
