Ethylene (C2H4) is used in fruit cool rooms to ripen the fruits. During ripening process fruits also generate ethylene which accelerates the ripening process. If fruits are over-ripped they start rotting giving out ethanol.
In order to control the right ripening of fruits users can use the Gas Alarm Systems ethylene gas detection system. The sensor works on dual beam infra-red sensing technology and has a range of 0 to 3% Vol (0-30,000 ppm ethylene). The transmitter gives out 4 to 20mA (24VDC, 3 wire) analogue signal output which can be connected to any PLC, SCADA or fruit cool room controllers.
The ethylene gas detection system/transmitter can also be supplied for on-line application for continuous on-line sampling of the ethylene dosing system. It comes with sample in-let and out-let ports.
Alternatively, the 4 to 20mA analogue output can be connected to Gas Alarm Systems’ range of MGC gas controllers for alarm generation, display of concentration and control of ventilation system or dosing of ethylene. The transmitter housing is made of ABS material (impact resistant, flame retardant), IP 65 and comes with splash guards for protection against water and dust. The ethylene gas detection system can be used in applications in fruit cool rooms, super markets, containers carrying fruits.
