Ethylene Gas Detector and Monitor

Ethylene (C2H4) Gas Detector and Monitor

ALVI Automation (India) Pvt Ltd, a Division of ALVI Technology Pty Ltd, Australia ( Td/As Gas Alarm Systems) is pleased to introduce our world-class cutting edge Ethylene (C2H4) Gas Detector and Monitor.

We are involved with designing, engineering, implementing, calibrating in the field of Gas Detection Systems, Instrumentation, Field devices, and Automation and several automation industries in the Australasian region including now in India. Our mission is to grow consistently using the best global technologies in products and services offered to customers. We aim to serve and maintain long term relationships by providing the most cost-effective appropriate solutions.


Ethylene(C2H4) detector is a highly robust, industrial grade, flameproof, or explosion-proof gas detector for Ethylene (C2H4) Gas leakage detection or LEL monitoring.

The detector is used for online, continuous monitoring of the flammable concentration of Methane Gas in %LEL or %Vol terms in ambient air or duct or pipeline. It is ATEX, IECEx certified with SIL 2 safety integrity level for hazardous area installation Zone 1 and 2.

With Benefits:

  • ATEX and IEC Ex certificates MSR-Electronic for electrical Ex protection
  • Metrological test & SIL2 safety functions 4–20 mA, RS485 and relay
  • For zone 1 (and also suitable for zone 2) Type “Ex db” with flame-proof enclosure
  • For zone 2: Type “Ex nA” with flame-proof enclosure

Ethylene (C2H4) Gas Detector for Fruit Ripening Application

What is Ethylene(C2H4)?

  • Ethylene (C2H4) is a colorless gas which is highly flammable with a Lower Explosive Limit of 2.7% in air.
  • Measuring range: 20-2000 PPM, 0-200 PPM, 0-100% LEL C2H4 with Semiconductor and Electrochemical Sensing Technology
  • Studies have indicated a low toxicity of ethylene and no risk to human health has been identified. It is naturally occurring, but it can also occur as a result of combustion and is manufactured by industrial processes from Methane and petroleum.
  • It has a slight ‘musky, sweet’ odour. Some fruit will produce C2H4 as ripening begins. Apples and pears are examples of fruit that produce ethylene with ripening. It is responsible for the changes in texture, softening, colour, and other processes involved in ripening.

Where is Ethylene (C2H4) Used?

C2H4 is widely used in the chemical industry. Polyethylenes of various density and melt flow account for more than 50% of world Ethylene demand. The primary use of polyethylene is in:

  • film applications for packaging, carrier bags and trash liners.
  • injection moulding
  • pipe extrusion
  • wire, cable sheathing and insulation,
  • extrusion coating of paper and cardboard.

C2H4 is the starting material for the preparation of a number of two-carbon compounds including Ethanol, Ethylene Oxide or converted Ethylene Glycol for antifreeze and Polyester fibres and films and Vinyl Chloride (converted to PVC). In addition to these compounds, ethylene and Benzene combine to form ethylbenzene, which is dehydrogenated to Styrene for use in the production of plastics and synthetic rubbers.
