Ethylene gas sensor INS-TR-C2H4-AF-4XX

C2H4for process measurementfor indoor air quality

Summary
The INS-TR-C2H4-AF-4XX is an ethylene (C₂H₄) gas sensor with an integrated digital display, designed to measure ethylene concentrations accurately in agricultural, food-processing, horticultural and industrial environments. It supports monitoring of fruit and vegetable ripening and optimising storage and transport conditions.

Typical applications

• Cold rooms
• Fruit storage warehouses
• Greenhouses
• Packaging and conditioning centres
• Food-processing facilities and industrial environments

Main features

• Built-in digital display for direct on-site reading
• Available measurement ranges: 0–10 ppm or 0–100 ppm
• High sensitivity and stable detection of concentration changes
• Plastic enclosure with protection (IP67 excluding sensor) for demanding environments
• Robust design and simple mounting

Integration & communications

• Power supply: 12–24 V DC
• Output signals: 0–10 V and 4–20 mA
• Digital communication: Modbus RTU

Maintenance & lifetime

• Average sensor lifetime: 2 years
• Replaceable sensor to reduce maintenance costs

Additional information
Designed to provide precise ethylene monitoring to control ripening and reduce losses due to improper ripening. The transmitter facilitates integration into automation, supervision and technical management systems thanks to its analog outputs and Modbus RTU interface.
