QPM11… QPM21… Duct Air Quality Sensors

•maintenance-free CO2 sensing element (depending on the type) based on opti-cal infrared absorption measurement (NDIR1)

•or with VOC2) sensing element, based on a heated tin dioxide semiconductor

•CO2 temperature (active or passive) and CO2 humidity-temperature multisensor • No recalibrations required

•Operating voltage AC 24 V or DC 15…35 V

•Signal outputs DC 0...10 V or DC 0...5 V adjustable

•Selectable passive temperature sensing element

USE

In air ducts of ventilation and air conditioning plant to enhance room comfort and to optimize energy consumption by providing demand-controlled ventilation. The sensor acquires:

•CO2 concentrations

•VOC concentrations as an indication of odors in the duct air, such as tobacco smoke,

body odor, or material fumes

•The relative humidity of the duct air

•The duct air temperature

Sensors QPM1100 and QPM21… can be used as a:

•Control sensor in the supply or extract air duct

•Transmitter for building automation and control systems and / or display units

(QPM21…D only).

Typical use:

•Acquisition of CO2 and VOC concentrations:

In party rooms, lounges, fair pavillions and exhibition halls, restaurants, canteens, shopping malls, sports gymnasiums, sales rooms, and conference rooms

•Acquisition of CO2 concentrations:

In ventilation plant of rooms with varying occupancy levels where smoking is prohibit-

ed, such as museums, theatres, movie theatres, auditoriums, office spaces and school rooms

•The QPM21… sensors are not suited for use as safety devices, such as gas or smoke warning devices!

•The sensors must not be used outdoors!

Sensors are widely used in various fields of social development and human life, such as industrial automation, agricultural modernization, space technology, military engineering, robotics, resource development, marine exploration, environmental monitoring, security, medical diagnosis, transportation, household appliances, etc.

The characteristics of the sensor include: miniaturization, digitization, intelligence, multi-functionalization, systematization and networking. It not only promotes the transformation and upgrading of traditional industries, but also establishes a new industry and thus becomes a new economic growth in the 21st century point. Miniaturization is based on microelectromechanical system (MEMS) technology, has been successfully applied to silicon devices made of silicon pressure sensors.
