Schadstoffe in der Raumluft – Raumluftmessung mit VOC-Sensoren

VOC-Sensoren erkennen Veränderungen der VOC-Konzentration in der Raumluft. Sie reagieren dabei nicht spezifisch auf einzelne Stoffe, sondern auf VOCs im Allgemeinen und auf Gase wie zum Beispiel Wasserstoff und Methan. Die Informationen von VOC-Gassensoren können genutzt werden, um den Betrieb von Luftreinigungs- oder Lüftungsanlagen zu regeln. Steigt der VOC-Gehalt in der Raumluft, …

Cylinder sensors - ifm electronic

Cylinder sensors. Cylinder sensors are used for position detection of pistons in pneumatic cylinders. They are directly mounted onto the cylinder. The ring magnet attached to the piston is sensed through the housing wall of non-magnetisable material ( aluminium, brass or stainless steel). They can be fixed to almost any T-slot, C-slot, clean-line, tie rod, integrated profile or trapezoidal ...

CO2 Monitoring for LEED Credit |

In addition, both LEED versions require CO2 sensors to be re-calibrated every 5 years, and for the sensors to be accurate to within 75ppm or 5% of the actual CO2 level, whichever is greater. What is different between LEED v3 and v4? The most current LEED certification is v4 and before gaining IEQ points in LEED v4, a “green cleaning” prerequisite has been added for commercial buildings ...
