General

The PMRMC Particulate Matter Sensor uses an optical sensor based on laser scattering principles and features innovative contamination resistance technology to perform highly accurate and reliable PM measurements. With a continuous-operation lifetime of more than 8 years, the sensor will provide long-term reliability and high resolution particle size binning for the detection of environmental dust and other particles.

The sensor is housed within an attractive, low-profile enclosure to monitor ambient PM levels for room applications. The sensor achieves excellent performance characteristics, including high accuracy and low power consumption to ensure stable long term operation. The PMRMC features both 4-20 mA and voltage outputs (0-5 / 0-10 Vdc) for simple integration into any building automation system to assure good indoor air quality. The device is also available with an RS-485 MS/TP network connection including either ModBus or BACnet protocol.
