Description

MAIN FEATURES

SAir sensors allow to get the measurement of some pollutant gas present in the air; SAir are provided of a sensible transducer which can get accurate measurements in industrial and external environments. Every sensor is electrochemical cell type, selective for the specific pollutant gas to detect.

The measurement provided by the cell is then linearized and amplified in the output as a 4…20mA analog electrical signal which can be interfaced with the most common dataloggers and PLCs available in the market.

SAir sensors are made of stainless materials so are suitable to work outdoor also in critical environmental conditions. Furthermore, thanks to a special filter and a protection shield, you get a better transducer response because the negative effect of atmospheric agents and dust is minimized; at the same time a natural air circulation is ensured to have always an updated fresh sample to detect.

The sensor mounting is very simple thanks to a supplied bracket that allows to fix it on horizontal or vertical ø25…43mm poles or on a wall.

 

 

ADVANTAGES 

  • Versatility of use
  • Good resolution (for high concentrations)
  • Calibration possibility for different measurement range
