Aerosol sensor welas® 2500 P

Aerosolsensor welas® 2100
Aerosol sensor pressure-resistant up to 10 bar overpressure

Depending on the aerosol composition to be measured, i.e., the carrier gas component and the particle material, pressure changes in the carrier gas can significantly influence the particle size distribution, e.g., due to condensation or evaporation.

For this reason, the aerosol sensors welas® 2070 P through to welas® 2500 P are equipped with a heatable cuvette to ensure isobaric and isothermal sampling down to the sensor's measurement volume.

The cuvettes are made of relaxed aluminum (black) by default. If the sensor is used in aggressive and corrosive aerosols, the cuvette can be made of stainless steel or other special materials, such as Hastelloy.

Sealed additional disks prevent aerosol from the cuvette from escaping into the surroundings. This even offers an advantage in measuring toxic substances under ambient pressure.

The additional disks are easy to clean and replace by the operator.
