Photoacoustic gas sensor from smartGAS
The PAS sensor is based on the measurement principle of photoacoustic spectroscopy (PAS), one of the most sensitive measurement methods for detecting gases. By spectrally tuning to the respective target gas, the PAS sensor achieves very high selectivity and delivers highly precise measurement results even at the lowest gas concentrations.
The sensor module can be operated via a downstream controller, but can also control a variety of processes and peripheral components itself. The PAS sensor is characterized by a very low zero drift and a very low influence by water vapor cross sensitivities.
Physical measuring principle – low drift, high accuracy
The new sensor now gives you even more assurance when using it in process measurement or gas analyzing applications. The physical measuring principle allows a low-drift measurement with high accuracy and high resolution over a long period of time. As the module is designed for continuous operation, it has an optional adjustable automatic zerocalibration function, alternatively this can be externally triggered.
