E2639-C2H4 is a detector designed for monitoring high concentrations of ethylene in the air. The device is equipped with a temperature-compensated sensor that ensures reliable detection and stable measurement, and it is housed in a wall-mounted enclosure with IP65 protection. The E2639 features three SPDT relays with a maximum load of 250 VAC 5 A. Two relays are used for so-called two-stage detection. The third relay indicates a sensor fault. Communication with higher-level systems is provided by the RS485 Modbus RTU digital interface, complemented by two 4–20 mA analogue outputs. In addition, the device includes four LEDs and an audible alarm to immediately alert operators when the set limit is exceeded directly at the installation site – without the need to monitor a remote control system.
The E2639-C2H4 detector is intended for monitoring ethylene in environments such as fruit and vegetable storage facilities, ripening chambers, greenhouses, food processing plants, and other operations where ethylene is used as a ripening regulator or where it may be unintentionally generated as a product of biological processes. The device helps prevent health risks associated with exposure to this gas and contributes to ensuring the safety of both personnel and operations.
Ethylene is a colourless gas with a faintly sweet odour that is practically undetectable at very low concentrations without the use of a detector. Although it is not directly fatal during short-term exposure, at higher levels it displaces oxygen in the air and may cause dizziness, disorientation, or loss of consciousness. However, the principal hazard is its high flammability — even relatively low concentrations of ethylene in the air can lead to explosion or fire in enclosed spaces, making it a gas that requires continuous monitoring.
The E2639 detector combines the advantages of an autonomous safety device and an intelligent communication node. It is designed for seamless integration with fire alarm systems (EPS) and offers a wide range of outputs for comprehensive control:
The E2639 is equipped with three M20 cable glands and a dual terminal block for Modbus RTU. The duplicated Modbus RTU terminals simplify and speed up bus wiring for data readout to the higher-level system. No more inserting two conductors into a single terminal. Thanks to the M20 glands, all required outputs can be connected conveniently.
Factory settings:
Each detector package includes the manufacturer’s original calibration certificate in English, confirming the accuracy and correctness of measurement at the time of leaving the factory.
