Technical Details for the different GasDec Sensors are
available.
GasDec Sensor with LED Indicators (red/green) for Error
Basic Standard GasDec Sensor has no LED displays
GasDec Sensor with LED Indicators as above AND Digital Display of the Gas
Concentration Values.
Some Customers want to install our GasDec Sensors themselves in their
monitoring/control system. This can be accomplished quite easily.
Description of above Wiring Connector Positions:
Left Column:
24 V DC Power Supply and 4 - 20 mA Output Signal
Middle Column:
A1 to A3 are three different alarm output connectors. At certain
pre-programmed gas concentration values, the signal on A1 to A3 changes from 0 V
DC to 24 V DC. This output can be sent to an indicator light/horn or to a relay
to control the power supply for a ventilation fan (for example).
Right Column:
F1 is a 24 V DC Input terminal, F2 is normally 24 V DC, when an Error is
detected the value drops to 0 V DC.
The individual GasDec Sensors can also be connected to a GasProtector. Each
GasProtector can connect to 6 GasDec Sensors and up to 6 GasProtectors can be
interlinked. The GasProtector has a digital display of the gas concentration but
also output terminals for alarm/control.
GasProtector
 CO-GasDec
RT Remote Measuring Head with Wireless Data Transfer
 For monitoring and alarm of high CO values in car parks, tunnels, engine test
and repair facilities etc. It is being used for automatic control of the
ventilation. It works with an electrochemic Sensor according to the
amperomectric principle. The data are transferred wireless. The power supply is
via battery with a typical life span of 3 years.
Key Benefits
- Professional Sensors from Swiss Manufacturer
- You can buy just components for your own system configuration or you can
buy a complete setup.
- Full backup and support by Roteq
