Evikon E2639-C2H2 is a detector designed for monitoring high concentrations of acetylene 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. The version with a Wi-Fi module enables wireless connection of a smartphone or tablet for configuration and calibration via a web interface – with no need to install an app. In addition, the device includes four LEDs and an audible alarm, which immediately alert operators to an exceeded set limit directly at the installation site – without the need to monitor a remote control system.
The E2639-LEL(C2H2) detector is suitable for industrial applications such as monitoring acetylene in workshops, production halls, storage areas or laboratories. The device is designed for reliable and safe gas detection, thereby supporting compliance with safety standards in the given environment.
Acetylene is an industrial gas with a faint ethereal odour, produced from calcium carbide or as a by-product of petroleum processing. Unlike many other flammable gases, it is hazardous even at very low concentrations, and its explosive range is among the widest of all industrially used gases. Under certain conditions, it can even explode without the presence of air.
The E2639 detector combines the advantages of an autonomous safety device and an intelligent communication node. It is designed for seamless cooperation with fire alarm systems (EPS) and offers a wide range of outputs for comprehensive control:
Compared to the standard version, the E2639-WF has an integrated WiFi module that turns calibration and configuration into a matter of minutes – without tools and without removing the cover. The access point is activated using a magnetic key, and the configuration interface opens in the browser of a phone or tablet, with no need to download any app. The interface is password-protected with separate access levels for end users and integrators, so everyone works only within their own part of the settings.
Factory settings:
Each detector package includes the manufacturer’s original calibration certificate in English, confirming the accuracy and correctness of measurement at the time it leaves the factory.
