The Senseca PMsenseCR is a high-precision particulate matter transmitter with an optional integrated CO₂ sensor, designed for environments where strict contamination control is essential, including pharmaceutical and high-tech cleanrooms.

The instrument uses laser scattering technology to detect and classify airborne particles according to their size. Its measuring concept is suitable for applications related to cleanroom contamination monitoring in accordance with ISO 14644 requirements.

PMsenseCR provides five particle-size measurement channels: Ch.1: >0.3 µm, Ch.2: >0.5 µm, Ch.3: >1.0 µm, Ch.4: >2.5 µm, and Ch.5: >5.0 µm.

The transmitter is designed for long-term stability, fast response, high sensitivity, and extended operating life, with no routine maintenance required.

An optional CO₂ sensor can be integrated on request, allowing simultaneous monitoring of airborne particles and carbon dioxide concentration in indoor environments.

The instrument can operate in either continuous or cyclic measurement mode. Cyclic operation helps extend sensor life, while continuous mode provides uninterrupted contamination monitoring.

For integration into automation and monitoring systems, the PMsenseCR supports an RS485 interface with MODBUS-RTU or proprietary ASCII protocol, as well as 4–20 mA analog outputs.

The Senseca PMsenseCR is suitable for cleanrooms, pharmaceutical manufacturing, high-tech production environments, laboratories, and other controlled areas where reliable monitoring of airborne particle concentration and particle size is required.
