Aerosolsensor welas® 1000

Aerosol sensor welas® 1200 HP

Aerosol sensor pressure-resistant up to 10 bar overpressure and heatable up to 120°C

Description

Depending on the composition of the aerosol 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 welas® aerosol sensors welas® 1100 HP and welas® 1200 HP are equipped with a pressure-resistant and heatable cuvette to ensure isobaric and isothermal sampling down to the sensor's measurement volume.

The cuvettes are made of anodised aluminium (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.
