#NSA-ASENSE-R-LCD-REL, NSA-ASENSE-R-LCD – 11/14/2019
Overview
The ASENSE Room Sensor series monitors the carbon dioxide (CO2) levels in commercial, school,
and office type environments. The concentration of CO2 is a strong indication of the overall indoor
air quality. The ASENSE Series is based on a single beam non-dispersive infrared technology and
is a cost-optimized solution for the climate control of buildings and other processes. In addition, ABC
software eliminates the need for manual calibration. The ASENSE Series measures the CO2
concentration in the ambient air up to 2,000 ppm and converts the data into an analog output. This
data can be used in conjunction with a Building Automation or Demand Control Ventilation System
to create a healthier indoor climate. This series features an analog temperature output (32 to 122°F)
and come with combined output options of 0-10 VDC and 0 to 20 mA (4 to 20 mA and 2-10 VDC are
field selectable via an onboard jumper) or 0-5 VDC for "-5" versions. A relay option is available for
this series as well. The UIP5 software and programming cable offer a configuration/test utility and
provide access to the main features of the ASENSE series.
Applications: Commercial Office Buildings, Gymnasiums, Shopping Malls, Auditoriums, Theaters, Hospitals & Schools
