Particulate Matter / CO2 Transmitter for Indoor Air
Whether in the pharmaceutical or high-tech sectors, cleanrooms are environments where attention to contamination must be paramount.
They must be closely monitored at all times to ensure that the required standards are met.
PMsenseCR is a particle counter transmitter suitable exactly for these applications.
PMsenseCR is a Particulate Matter (PM) and optionally CO2transmitter, ideal for pharmaceutical and high-tech cleanrooms where contamination control is critical.
Particularly suitable for controlled environments
The measuring principle is based on the laser scattering method: it counts and classifies particles according to their size in order to monitor a cleanroom
environment as described in the ISO 14644 standards.
Excellent long term performance
The transmitter is maintenance-free and has fast response, high sensitivity, excellent stability and long operating life.
Reliable & Maintenance-Free
Built for long-term stability, PMsenseCR offers fast response, high sensitivity, and extended operating life - no routine maintenance required.
Optional CO₂ Sensing
Add an integrated CO₂ sensor for comprehensive indoor monitoring.
Measuring cycle interval user configurable
The measuring circuit of the transmitter can be operated in continuous mode (default operating mode) or, in order to extend the PM sensor lifetime, at cyclic
intervals.
Output flexibility
Digital RS485 output with MODBUS-RTU or ASCII proprietary protocol or version with two additional 4…20 mA outputs. The two analog outputs can be
independently associated with any of the measured parameters.
Very flexible with regards to the choice of outputs and fully equipped with 5 channels:
- Ch.1: >0.3μm
- Ch.2: >0.5μm
- Ch.3: >1.0μm
- Ch.4: >2.5μm
- Ch.5: >5.0μm
The PMsenseCR is available in four variants (please select when ordering):
PMsenseCR-M PM transmitter with RS485 MODBUS-RTU output
PMsenseCR-A PM transmitter with RS485 MODBUS-RTU output + two 4...20mA outputs
PMBsenseCR-M PM & CO2 transmitter with RS485 MODBUS-RTU output
PMBsenseCR-A PM & CO2 transmitter with RS485 MODBUS-RTU output + two 4...20mA outputs
