Transmitter EC28 D

Product catalog summary

Overview: The EC28 D Transmitter is designed for monitoring toxic gases, hydrogen, and oxygen, displaying current measured values locally. It is ATEX-certified for use in potentially explosive atmospheres and complies with the European Functional Safety Standard DIN EN 61508-2: 2011.

Specifications: The transmitter operates with a 4 to 20 mA signal and features Smart Sensor technology for easy sensor replacement. It includes a 2.2-inch LC display and three control buttons for displaying measured values, faults, alarms, and operating parameters. The device supports remote control via the optional RC2 for servicing in hard-to-reach locations.

Variants: The EC28 series offers multiple versions to suit different applications, including basic models, those with displays, alarm horns, Modbus interfaces, and intrinsically safe options.

Technical Data: The EC28 D uses electrochemical measuring principles and supports diffusion or gassing gas supply. It operates in temperatures from -20 to +50 °C in Ex zones and -25 to +50 °C outside Ex zones, with humidity tolerance from 5 to 90% r.h. The device is housed in plastic with IP64 protection, measuring 115 x 203 x 55 mm and weighing 800 g.

Approvals and Certifications: The transmitter is marked with II 2G Ex eb mb [ib] IIC T4 Gb and is certified for functional safety (SIL) under DIN EN 61508-2: 2011.

Gas Detection Capabilities: The EC28 D can detect a variety of gases, including ammonia, chlorine, hydrogen chloride, carbon monoxide, ozone, and more, with specific SI levels for each gas.
