For Food Technology, Horticulture, Environment
As high concentrations of CO2 are clearly hazardous, most countries
have set exposure limits in the workplace. Applications where carbon dioxide can rise to dangerous levels include the brewing and carbonated drinks industries, food freezing using dry ice, cold storage, cargo ships, and, of course, plants where CO2 or dry ice is produced or handled.

Vaisala's GMT220 series are the first CARBOCAP® transmitters available
for a wide range of industrial CO2 applications including
greenhouses, fruit storage, safety alerts and demand-controlled ventilation
in mushroom farms, livestock husbandry and parking garages.
The GMT220 series transmitters are designed to measure CO2 in harsh and humid
environments.
The housing is dust and water proof to IP65/NEMA4. The materials have
been chosen for extended corrosion resistance
The transmitter is easy-to-use and easy to install.
The GMT220 series transmitters have a modular structure, which includes a separate
mounting plate that eases the installation.
Since the probes of the transmitter are truly interchangeable, they
facilitate the field maintenance.
The probes can either be replaced by newly calibrated probes or separate ones
that can be used as reference probes for calibration checking.
This minimizes the downtime and eliminates the need for expensive calibration
equipment.

Technical specifications
Measurement range: 0...2000 ppm (nominal, can be calibrated for other ranges)
Accuracy: ± 30 ppm + 2 % of reading
Operating temperature: -5...+45 °C
NDIR = Non-Dispersive Infra Red (makes the sensor highly gas specific).
The individual sensor types have a 3rd letter in the part no, e.g. GMD... (duct mount) or GMW... (wall mount)
The GMW20 series transmitters can be used independently or they can be incorporated
into building energy management systems.
The wall mount GMW series transmitters are available in two sizes (GMW21
and GMW22).
The GMD20 is a duct mountable transmitter.
Optional LonMark® approved interface modules are available for digital communication between the transmitters and a LonWorks network.
An analogue temperature option is available for the GMW21.
The GMA20T offers active temperature measurement using a semiconductor sensor IC.
The measurement module has a voltage output of 0...10 V, corresponding to a measurement range of 0...50 ºC.
The accuracy of the module is 0.5 ºC.
Nominal range of the CO2 sensors is 0..2000ppm.
They can be calibrated for other ranges: 0...5000ppm, 0...10,000ppm,
0...20,000ppm

The GMW21D is an ideal CO2 sensor for controlling ventilation in buildings
to control indoor CO2 and air quality levels. It has a relay output which
can be used to switch on a ventilation fan when the CO2 level becomes too high
(e.g. due to a large number of people being in the room for a long time).
The GMW21D is shipped with a pre-set threshold of 1000ppm, which is the CO2
level recommended for optimum indoor air quality and comfort by ASHRAE (American
Society of Heating Refrigeration and Air Conditioning Engineers). However if
this threshold is not suitable for an application, the CO2 threshold can be
adjusted by connecting the sensor to a PC and running the Vaisala PC software.
Note that for controlling ventilation in rooms, the GMW21D should typically
be wall-mounted at head height, away from any air conditioning or ventilation
ducts. See the link above for full data.
Note: the relay output rating on the GMW21D is 50V / 0.5A, so in most cases
it is necessary to connect it via another power relay for switching a mains
powered ventilation fan.
