NextPM Advanced
Controlled-sampling PM sensor for remote, duct and high-concentration monitoring
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.
- External pump architecture
- Controlled sampling flow
- Up to 10,000 µg/m³
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.
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.
Adapt the airflow to the sampling line and pressure conditions of the final system.
Install the sampling inlet at the relevant measurement point while locating the sensor elsewhere.
Monitor higher concentrations under the specified sampling and calibration conditions.

Resources for integrating NextPM Advanced
NextPM Advanced is supplied with the technical resources required for mechanical, electronic and software integration.
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.

FAQ
NextPM includes an integrated airflow architecture for compact ambient-air and distributed OEM monitoring. NextPM Advanced is designed to operate with an external pump when controlled airflow, remote sampling or higher particle concentrations are required.
Yes. NextPM Advanced uses an external pump to generate the sampling flow. The pump and its operating parameters must be selected according to the sampling line and final application.
The pump can be supplied or specified as part of the project configuration. Contact TERA Sensor to define whether the standard compatible pump or an application-specific solution is required.
Yes, it can be integrated into a duct-sampling architecture. Pressure, airflow, tubing, inlet location and particle transport must be considered when designing the final system.
NextPM Advanced is designed for concentrations up to 10,000 µg/m³ under the specified test, sampling and calibration conditions. Actual performance depends on the aerosol and final measurement architecture.
Tubing length, diameter, material, bends and airflow can cause particle losses or change response time. These effects are particularly important for larger particles and must be considered during system design.
Yes. TERA Sensor can support sensor and pump selection, airflow and tubing design, electronics, communication, calibration and prototype validation. TERA Tronics can then support industrialization and series manufacturing.
