Description

Depending on the composition of the aerosol to be measured, i.e. the carrier gas component and the particle material, pressure and temperature 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 cuvette heatable up to 120 °C and pressure-tight up to 10 barg to ensure isobaric and isothermal sampling into the sensor’s measurement volume.

The welas® digital is usually calibrated for the operating volume flow. As the operating volume flow changes with pressure and temperature, it is advantageous for the user if automatic volume flow regulation for the sampling volume flow is provided for in the device.

In the Promo® 1000 HP the pressure and temperature of the carrier gas are measured and the required operating volume flow is automatically set to 5 l/min.

Includes:
•    Mass flow controller for volume flow regulation
•    Heating regulator up to 120 °C
•    Temperature sensor
•    Absolute pressure capsule
•    Filter unit
