GfG Controller for up to 8 or 16
sensors
Gases are used in
many areas as technical production or working materials. They are stored,
transported, or occur as waste. These gases are often toxic and thus present
handling problems.
Most toxic gases are not perceptible to human senses. However, even minimal
concentrations can cause acute poisoning or long-term damage. |

Remote sensors are installed where toxic gases can occur and
endanger human beings. Even minimal gas concentrations are
detected by the remote sensor and transmitted to a monitoring
and analysis unit in the form of current and voltage signals.
The three measuring processes (chemosorption, carrier injection,
electrochemical and infrared sensors) enable a wide variety of
measuring requirements in respect of toxic gases to be met.
Here is a small extract from more than 100 different toxic gas
hazards:
ammonia, chlorine, carbon monoxide, sulphur dioxide, hydrogen
sulphide, nitrogen oxide, FCs and CFCs (Freons), as well as
carbon dioxide, etc.

State-of-the-art Monitoring of
Toxic and Combustible Gases
ATEX certified
|
Advanced technology
Wherever hazards are induced by combustible gases or vapours,
the transmitter CC28 and GfG's proven controllers are the best
solution for reliable surveillance. The ATEX-certified design (`
II 2 G EEx dem [ib] IIC T4), a built-in, Ex-proof buzzer and
bright alarm LEDs provide safe operation including visual and
audible warning even in hazardous areas. Thus the gas alarm does
not only alert the man in the control room but also the person
at site. |

Smart sensors
The Smart Sensor Technology makes installation or sensor
replacement a matter of seconds - just plug the sensor into the
transmitter. Adjustments are done with touch keys directly at
the transmitter or by means of the remote control (one man
calibration).
Remote Control RC2
Several combustible gases are lighter than air. With the
transmitter installed close to the ceiling, the remote control
allows to do all adjustments without having to climb up a ladder.
A helix cable connects the remote control to the transmitter.
The display of the remote control always shows the same reading
as the transmitter. The remote control facilitates inspection,
service and calibration considerably. Additionally the
indication of the present gas concentration allows to use the
remote control as an external display.

Toxic Gases
Reliable detection,
minimized cost of ownership, increased safety
The sensor and the integrated temperature compensation provide
highest measurement accuracy. Low maintenance requirements and
long sensor life reduce your cost of ownership. Just sign a
service contract and don't worry about any problems. We will
service your system in regular intervals.
Integrated alarm - No
cost for Ex-buzzer, Ex-light and wiring!
With model CC28 D the present gas concentration can be read at
site from the display of the transmitter - and from the GMA
controller.
Model CC28 DA provides additional warning by means of bright
alarm LEDs and buzzer - thus avoiding additional expenses for
Ex-proof buzzers and lights and for the wiring from controller
to alarm devices. In combination with GfG's most flexible
control monitors the CC28 provides extraordinary solutions for
favourable and reliable monitoring of combustible gases.
Advantages at a
glance
- Display of gas concentration at display or at
remote control
- ATEX `

- Ex-proof visual and audible alarm
- No need of expensive Ex-buzzer, considerably
less wiring
- Smart Sensor System - easy sensor replacement by
plug-in sensors
- Long sensor life
- Low service requirement
- Permanent status display (operation/fault/service)
at transmitter
- Adjustments with touch keys or remote control,
without opening the casing
- Easy handling even in hardly accessible
transmitter position (e.g. below ceiling

Oxygen sensor O2
Oxygen is an
essential gas for all living things. In fresh air the oxygen concentration is
approx. 20.9 vol.%. Fluctuations in the oxygen concentration in fresh air are
extremely small. Our organism reacts all the more sensitively to any change in
the concentration in the air we breathe.
For areas in which only a small residual oxygen content is permissible, the low
concentration is monitored with a remote sensor for small measuring ranges.

without saying that the body (controller) should also be as good and

GMA
160.pdf
If you look to the
future, you'll opt for the state-of-the-art, microprocessor-controlled GMA
160 monitoring and control device. The practical, space-saving multiplexer
structure has many advantages. For one, it is compact and is very easy to
install without using a rack; for another, 8 sensors can be connected at once to
the GMA 160. As you can see, the price/performance ratio of the GMA 140 is
right.
Special edition for CO (Cabonmonoxid) used in detection of CO in garages with a
possibility of connection till 8 or 16 sensors.
You'll see it - we are one step before and if you want you too.

GMA 011Controller for one
measuring point

GMA011engl.pdf
All sensors for air quality monitoring and also the measuring
signals from water measurement technology (MiniCal II) can be connected to the
modern GMA 011 controllers. The unit displays the physical unit of measurement
and measuring range as well as continuously indicating the measured value. Limit
values, 3 relays for limit values I, II and technical malfunction can be used
for switching/signalling via the microprocessor with 2-key operation. The
easy-to-install snap rail attachment enables the units to be mounted quickly,
without using a rack. Further advantages are 230 VAC or 24 VDC power supply, mA
output, external acknowledgment, etc., etc.
These units are ideally suitable for combination when
measuring different gases and for water measurement technology. Further
advantages are display and evaluation for each sensor.
