Schabus GX-D500 Carbon dioxide detector incl external sensor mains-powered detects Carbon dioxide
The CO2 warning detector GX-D500 is a prof. Warning device with fixed alarm thresholds at 1.5% CO2 for pre-alarm and 3.0% CO2 for main alarm. The application is versatile, whether it is the monitoring of large CO2 bottles for water carbonators, the occupational safety during the processing and storage of dry ice or the reporting of increased carbon dioxide concentrations in small to medium-sized breweries or wine and fermentation cellars.The threshold value for the alarm, which is clearly visible both acoustically and optically, was deliberately chosen so high that poor ambient air through exhaled CO2 does not lead to false alarms by humans, but defects in technical equipment are detected immediately and safely. The exact alarm thresholds and the degree of protection are based on the specifications of the technical guidelines for beverage dispensing systems in the catering industry.The external sensor with IP54 degree of protection for spray water is pre-assembled with a 4 meter long 3-wire cable. With a 3x 1.5 mm² cable, the sensor cable can be extended to up to 100 meters.In the event of an alarm, a potential-free changeover relay (230 V~ / 5 A) switches over, for example Force vents or close solenoid shut-off valves. Another potential-free changeover relay (60 V= / 5 A) switches over in the event of technical faults detected by the device itself and thus informs, for example, the building control system. In monitoring mode, both relays are activated and fail in the event of an alarm/fault.A large illuminated 2 x 16 character display constantly informs about the currently measured CO2 value in percent and when scrolling through the display with THE SERVICE key about further status messages of the device. The temperatures inside the device are monitored, the alarms are counted, an error code is displayed in the event of technical faults, or the CO2 concentration is also recorded in percent at the last alarm.A special feature of this CO2 detector is that the user can calibrate the sensor itself to a zero point. Like any other sensor, the sensor is subject to natural drift, which makes it less sensitive over time. Especially in applications where the sensor is exposed to a constantly increased CO2 concentration and does not regularly, at least weekly, get real fresh air, an auto-calibration could show completely wrong values over time. For this reason, we have switched off the usual auto-calibration with this type. The software-defined spread of the alarm thresholds remains fully maintained.For calibration, the sensor is operated for at least 30 minutes in real fresh air (approx. 0.04% CO2) and then the calibration button is pressed. This new sensor no longer has to be sent to Schabus for zero point calibration as before. On request, however, we continue to offer this service as usual.Possible applicationsSmall to medium-sized breweries, wine and guest cellarsCatering (beverage dispensing systems)Dry ice storage and processing (vaccination centers, street food trucks, â¦)All systems with CO2 from pressure cylinders (laboratories, warehouses, â¦)And all systems in which a GX-A1 with GX-CO2-30 sensor was previously used.This text is machine translated.
