The GMA 011 RC Gas Controller is an alternative to
conventional arrangements with separate sensor and analyzing unit.
The usual principle in gas measuring technology is "head and board",
by which the gas measurement specialist means a sensor connected to a
plug-in unit or a controller. In this case the limit contacts and other
settings are performed on the decentralized controller/plug-in unit.
The GMA 011 RC (relay contacts) offers a very different approach.
In the stand-alone version both components are combined in a housing –
with many advantages.
- controller/sensor in a single unit
- integrated relay contacts
- clear display of the measured value large LED display operating contact display
- programming mode display
- test and acknowledgment key
- 4 floating relay outputs
- programming via membrane keyboard of:
Range: 0..300/500/1000 ppm NH3
- operating temperature -30..40°C
24 VAC or DC
output signal 4..20 mA
Relais contacts pre-alarm, alarm and function control

The Multifunctional Gascontroller
Air – the
source of human life – monitored by the latest gas measuring technology for
toxic and explosive gases – for example,
CO in
garages, natural gas in central heating plants Freon, NH3 in refrigeration
plants chlorine, ozone in swimming pools
GMA 160 for CO and NO - Environmentaloriented,
compactly, reliably
The new measuring instrument
consists of a sensor, which measures both relevant exhaust concentrations CO
(Carbon monoxide) and NO (nitrogen monoxide) with two sensors integrated in
the Feeler housing. The signals are passed on at the new gas CONTROLLER
GMA160.CO/NO and these switch into dependence of the different limit values
for CO and NO the ventilation stages and if necessarily the alarm
signalling. The concentrations are shown separately over two announcements
integrated in the CONTROLLER.
Sensors with (CO and NO) with two
integrated cell for Diesel and Benzine in Garages and Tunnels.
