SPECIFICATION DATA & INSTALLATION INSTRUCTIONS

GENERAL

The C7110A Room Air Quality Sensor is suitable for

measuring air quality in rooms, offices, and production bays.

This mixed gas sensor can be used to control ventilation
plants. It detects unpleasant odors, tobacco smoke, and

vapors emitted by such materials as furniture, carpets, paint,

glue, etc. As proven in practice, this device detects those
substances typically present in air having a poor quality,

some of which may otherwise go undetected by room

occupants, themselves. This sensor has proven itself in
numerous applications over many years.

FUNCTION

The electrical conductivity of a heated tin-dioxide semi-
conductor sensor varies in proportion to the number of mole-

cules of the reducing agents. This leads to a voltage at the

measuring element which is amplified to an output voltage of
0V to 10Vdc.

The following particles and gases can be detected: cigarette
smoke, hydrogen, carbon monoxide, ethanol, ammonia, etc.

In contrast to CO

sensors, which selectively measure the

concentration of only one type of gas, a mixed gas sensor is a

broadband detector, i.e. the sensor signal does not indicate
the type of gas or its concentration in ppm (parts per million).

The complex and constantly changing composition of room

air makes it necessary to perform broadband air quality
measurement.
