Transmitter EC28 DA

Product catalog summary

Overview: The EC28 DA Transmitter is designed for monitoring toxic gases, oxygen, or hydrogen in potentially explosive atmospheres. It features a display for current measured values and an alarm system, making it suitable for use in Ex zones. The device is ATEX-certified 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 includes Smart Sensor technology for easy sensor replacement. It has a 2.2-inch LC display, three control buttons, red alarm LEDs, and a 90 dB horn. The device ensures reliable measurement with minimal operating costs due to its long sensor life and low maintenance requirements.

Variants: The EC28 series includes several versions to meet different application needs, such as the basic EC28, EC28 D with display, EC28 DA with alarm features, and EC28 B with Modbus interface. Intrinsically safe versions are also available.

Technical Data: The transmitter uses an electrochemical measuring principle and supports diffusion or gassing per calibration adapter. It operates in temperatures from -20 to +50 °C in Ex zones and -25 to +50 °C outside Ex zones, with humidity levels of 5 to 90% r.h. It requires a power supply of 18 to 30 V DC and has a protection class of IP64.

Gas Detection and Safety Levels: The EC28 DA can detect various gases, including ammonia, chlorine, hydrogen chloride, carbon monoxide, and more, with safety integrity levels (SIL) up to SIL3 in single-channel or redundant use.

Certifications: The device is marked with II 2G Ex eb mb [ib] IIC T4 Gb, indicating its suitability for use in explosive atmospheres. It adheres to the functional safety standard DIN EN 61508-2: 2011.
