CONTROLLED SAMPLING · HIGH CONCENTRATION

NextPM Advanced combines the optical measurement principles of NextPM with an external sampling pump. This architecture allows the airflow through the sensing element to be controlled according to the sampling line, pressure conditions and concentration range of the final application.

It provides PM1, PM2.5 and PM10 mass concentrations together with particle information across five size channels for applications requiring remote sampling, duct measurement or particle concentrations up to 10,000 µg/m³.

SAMPLING CHALLENGES

Some monitoring applications require more than an integrated sensor airflow

Compact PM sensors usually sample air directly around the sensing element. This architecture becomes limiting when the measurement point is located inside a duct, behind a sampling line or under different pressure conditions.

In these situations, airflow, pressure losses, tubing and particle transport must be considered as part of the complete measurement architecture.

Remote measurement points

The sensing element may need to sit away from the sampling location because of space or accessibility constraints.

Pressure differences

Duct pressure or enclosure conditions can influence the airflow through an integrated sensor architecture.

Sampling-line losses

Tubing length, diameter and bends can affect particle transport before the aerosol reaches the sensor.

Higher particle concentrations

Industrial environments may generate concentrations beyond the range of standard ambient-air configurations.

SOLUTION ARCHITECTURE

NextPM Advanced combines particle sensing with externally controlled airflow

NextPM Advanced retains the optical measurement principles of NextPM while replacing the integrated airflow architecture with an external pump. This allows the sampling flow to be adapted to the sampling line, pressure conditions and concentration range of the final application.

Designing a controlled particle-sampling system?

In a remote or controlled-sampling system, sensor performance depends on more than the sensing element alone. Pump selection, airflow, tubing diameter, sampling-line length, bends, inlet geometry, particle losses, electronics and calibration can all influence the final measurement.

TERA Sensor can support the definition of the measurement need, sensor and pump selection, fluidic architecture, electronics, firmware, calibration strategy and prototype validation. Through TERA Tronics, the project can then be supported through industrialization, electronic manufacturing and series production.
