Transmitter EC28 i

Product catalog summary

Overview: The EC28 i Transmitter is designed for monitoring toxic gases, oxygen, and hydrogen in areas with explosion risks. It is intrinsically safe and works with GfG's control units, using two-wire cabling for power supply and data transmission.

Intrinsically Safe Operation: The EC28 i is ATEX-certified for use in Ex zone 0. It requires a safety barrier to convert supply voltage to 24 V DC, preventing ignition in explosive zones.

Communication and Service: The transmitter communicates via a 4 to 20 mA signal. It features Smart Sensor technology for easy sensor replacement and can be calibrated using the optional RC2 remote control.

Remote Control RC2: This optional tool allows for ground-level maintenance of ceiling-installed transmitters, displaying the same information as the EC28 with a display.

Measurement and Costs: The EC28 i ensures accurate measurements with temperature compensation, offering long sensor life and low maintenance costs.

Variants: The EC28 series includes various models for different needs, such as versions with displays, alarm systems, and Modbus interfaces.

Technical Data: The EC28 i supports a wide range of gases, operates on electrochemical principles, and functions within specific temperature, humidity, and pressure ranges. It outputs a 4-20 mA signal and requires a power supply of 15 to 30 V DC.

Certifications: The device is marked with II 1G Ex ia IIC T4 Ga, suitable for temperatures between -20°C and +50°C.

EC28 i Transmitter Intrinsically Safe for Toxic Gases, O2 and H2 Where toxic gases, oxygen or hydrogen are to be monitored in areas with a particular risk of explosion, the intrinsically safe EC28 i 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. Due to its intrinsically safe build, the EC28 i can be used even in areas with a particularly high risk of explosion. A safety barrier (SB1 or Zener barrier; optionally available) has to be connected between the transmitter...
