· Maintenance-free CO

sensing element (depending on the type) based on opti-

cal infrared absorption measurement (NDIR

)

· Or with VOC

sensing element, based on a heated tin dioxide semiconductor

· CO

temperature (active or passive) and CO

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 or 4...20 mA adjustable

· Selectable passive temperature sensing element

1) NDIR = Non dispersive infrared

2) VOC = volatile organic compounds (also called mixed gas)

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:

· CO

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 CO

and VOC concentrations:

In party rooms, lounges, fair pavillions and exhibition halls, restaurants, canteens,

shopping malls, sports gymnasiums, sales rooms, and conference rooms

Mode of operation CO2 concentrations The SymaroTM air quality sensors acquire the CO2 concentration by infrared absorption measurement (NDIR). The resulting output signal of DC 0...10 V or DC 0...5 V or 4...20 mA is proportional to the CO2 content of the ambient air.
