Aerosol sensor welas® 2070 HP

Aerosolsensor welas® 2070
耐压版本,最高承受 10 bar 过压,可加热至 120 °C

Depending on the aerosol composition to be measured, i.e., the carrier gas component and the particle material, pressure or temperature 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 HP through to welas® 2500 HP are equipped with a heatable cuvette to ensure isobaric and isothermal sampling down to the sensor's measurement volume.

The cuvettes are made of anodized aluminum (black). 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.

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