Transmitter EC28 Di

Product catalog summary

Overview: The EC28 Di Transmitter is designed for monitoring toxic gases, oxygen, and hydrogen in explosion-prone areas. It is intrinsically safe and provides local display of measured values, making it a reliable and cost-effective solution when used with GfG's control units.

Intrinsic Safety: The EC28 Di is ATEX-certified for intrinsic safety, suitable for Ex zone 0 applications. It requires a safety barrier to convert supply voltage to 24 V DC, preventing ignition in explosive zones.

Communication and Service: The transmitter uses a 4 to 20 mA signal for communication. It features Smart Sensor technology for easy sensor replacement.

Display and Control: Equipped with a 2.2-inch LC display and three control buttons, the EC28 Di shows measured values, faults, and alarms. Operating parameters can be accessed via control buttons.

Remote Control: An optional RC2 remote control is available for servicing and adjustments in hard-to-reach locations, displaying the same information as the transmitter.

Measurement and Costs: The transmitter ensures high measuring accuracy with temperature compensation, long sensor life, and low maintenance costs.

Variants: The EC28 series includes various models to meet specific needs, such as versions with displays, alarm horns, Modbus interfaces, and intrinsic safety features.

Gas Detection: The EC28 can detect a wide range of gases including ammonia, chlorine, hydrogen sulfide, and more.

Technical Data: The EC28 Di uses electrochemical measuring principles, operates in temperatures from -20 to +50 °C in Ex zones, and has a protection class of IP64. It weighs 800 g and measures 115 x 203 x 55 mm.

Certifications: The device is marked with II 1G Ex ia IIC T4 Ga, indicating its suitability for hazardous environments.

Intrinsic Safety and Display for Toxic Gases, O₂ and H₂ Where toxic gases, oxygen or hydrogen are to be monitored in areas with a particular risk of explosion and measured values are to be read locally, the intrinsically safe EC28 Di transmitter along with GfG‘s control units is a reliable and cost-effective solution. The power supply and transmission of the measured values are carried out via two-wire cabling. Intrinsically safe operation Due to its intrinsically safe build, the EC28 Di can be used even in areas with a particularly high risk of explosion. A safety barrier (SB1 or Zener barrier;...
