The GMW86P and GMW86PT transmitters.
The Vaisala CARBOCAP® Carbon
Dioxide and Temperature Transmitter
Series GMW80 is based on a
second-generation technology for
improved reliability and stability. The
transmitters are designed to fulfill
the needs for CO2 measurements
in standard demand-controlled
ventilation applications. Temperature
measurement is always included
in the GMW80 series transmitters.
The optional temperature set-point
potentiometer gives you the flexibility
needed for a variety of projects.
The CARBOCAP® sensors measure CO2
accurately immediately when powered
on. As they have a built-in reference
measurement they do not need a
lengthy learning phase before the
measured values are correct. Proper
operation can be verified immediately
after snapping on the device cover.
Easy Installation
Reliable Operation
With modern buildings often having
hundreds of sensors, the installation
time per unit can be a significant
cost factor. Returning to the building
site to check sensor operation adds
further costs.
The GMW80 series transmitters are
optimized for low maintenance. The
second-generation, low-power
CARBOCAP® technology enables
a longer lifetime and superior
stability than ever before. As the
power consumption is low, the heat
generated by the electronics does
not distort the temperature inside
the sensor. The internal reference
in the CO2 sensor guarantees the
best stability and operation even
in constantly occupied buildings
without frequent readjustments.
The GMW80 series transmitters
include a number of subtle design
features that have been introduced to
make installation and commissioning
quick and easy. The pull-out tab
makes opening the transmitter faster
than before, while also doubling as a
quality check slip and holder for the
anti-tamper screw. The backplate can
be twisted onto pre-mounted screws,
and the wiring can be done easily on
the clearly marked backplate. The
electronics can be snapped on later
when the building automation system
is commissioned.
The reliable operation and accurate
measurement values of the GMW80
series transmitters contribute to the
significant cost savings brought by
demand-controlled ventilation.
