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.

NDIR = Non-Dispersive Infra Red (makes the sensor highly gas specific).
CarboCap
NDIR Transmitters (Infra Red) These CO2 transmitters use the
new silicon based CARBOCAP® sensor.
The simple structure and reference
measurement capabilities make this
Single-Beam Dual-Wavelength
NDIR sensor extremely stable and reliable.
The measurement accuracy of the
sensor is not affected by dust, water vapor or most chemicals.
The Vaisala
GMD20 / GMW20 transmitters are easy to install and require almost no maintenance
(the recommended calibration interval is five years).
They are specially
designed for Demand Controlled Ventilation and related applications.
The
use of these transmitters results in considerable savings in installation, operation,
maintenance and recalibration costs
as well as ensures the best possible control
of air quality.

New product:
Carbon
dioxide & temperature transmitter for HVAC applications
The new Vaisala CARBOCAP® Carbon Dioxide and Temperature Transmitter GMW116 is a wall-mounted sensor designed for HVAC applications.
It has all the benefits familiar to the GMW115 CO2 transmitter with its proven track record:
• Ideal
for ventilation control in all types of occupied spaces including those with round-the-clock
occupancy
• Advanced single-beam dual wavelength measurement with no moving
parts
• Excellent long-term stability
• Warranty time 2 years
The GMW116 has two 0 ... 10 V outputs scaled 0 ... 2000 ppm CO2 and 0 ...
50 °C.
As the GMW116 measures the temperature it can naturally compensate
for the ideal gas temperature dependence causing most of the temperature dependence
in CO2 transmitters.
It offers these additional benefits:
• No need
for temperature compensation
• Compact dual-parameter transmitter; measures
both CO2 and T

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.

The GMT222 is very well suited
to monitoring CO2 levels in car parks for demand controlled ventilation,
as it is protected against the harsh dust, water and exhaust fumes that often
exist in car parks. Its built-in dual alarm relays can be factory pre-set to switch
on at a given CO2 concentration, making the GMT222 a simple solution for the task.
Typically for car parks these sensors are configured for a measurement range of
0-5000ppm, and the alarm set point can be configured as per council requirements
(usually 1000ppm or higher).

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.
The GMW21 is only recommended
for use indoors, as its electronic circuit board is exposed to the air.
For
use in locations such as car parks, the GMD20D is better suited, as its electronic
circuit board is fully enclosed so it will not be affected by the harsh dust,
exhaust fumes and occasional water droplets that can occur in car parks. However
for maximum reliability in environments such as car parks, it is recommended
to use the GMT222 (above) which is designed for use in harsh environments.
