GMW116 Carbon Dioxide and Temperature
Transmitter for Ventilation Control
The Vaisala CARBOCAP
®
Carbon Dioxide and Temperature Transmitter GMW116.
The Vaisala CARBOCAP
®
Carbon
Dioxide and Temperature Transmitter
GMW116 is the compact-size
transmitter that measures both
carbon dioxide and temperature. The
sensor is accurate and durable and it
has an excellent long-term stability,
which decreases maintenance.
The excellent performance of the
Vaisala CARBOCAP
®
sensors results
largely from the stable reference
provided by the electrically tunable
Fabry-Perot Interferometer (FPI).
In buildings with around-the-
clock occupancy (e.g. hospitals,
work-places, residential buildings,
retirement homes), the assumed
Features/Benefi ts
▪
Compact dual-parameter
transmitter: measures both
CO
2
and T
▪
Incorporates Vaisala
CARBOCAP®, the silicon based
NDIR sensor with unique
internal referencing
▪
Advanced, single-beam, dual
wavelength measurement with
no moving parts
▪
Excellent long-term stability
▪
Ideal for ventilation control in
all types of occupied spaces
including those with around-
the-clock occupancy
▪
No need for temperature
compensation
background CO

level reference
is simply not applicable. The true
internal reference measurement of
Vaisala CARBOCAP

transmitters
provides years of stable CO
2
measurements.
The GMW116 Transmitter is designed
especially for demand controlled
ventilation applications with CO
2
measurement range of
0 … 2000 ppm and temperature range
of 0 ... +50 °C.
With GMW116 there is no need for
temperature compensation. The ideal
gas temperature behaviour is taken
into account automatically.
