Transmitter EC28 B

Product catalog summary

Overview: The EC28 B Transmitter is designed for monitoring toxic gases, oxygen, or hydrogen, and transmitting measured values digitally. 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 uses an electrochemical measuring principle and supports gas supply via diffusion or gassing per calibration adapter. It operates in temperatures ranging 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. The output signal is RS-485, and it requires a power supply of 18 to 30 V DC. The housing is plastic with an IP64 protection class, and the dimensions are 115 x 203 x 55 mm, weighing 650 g.

Communication and Service: Communication is facilitated through the RS-485 industry standard with Modbus protocol. The Smart Sensor technology allows for easy sensor replacement, and adjustments can be made using the optional RC2 remote control, which simplifies maintenance and calibration.

Variants: The EC28 is available in several versions to meet different application needs, including basic, display-equipped, alarm-integrated, Modbus interface, and intrinsically safe versions.

Technical Data: The transmitter is marked with II 2G Ex eb mb [ib] IIC T4 Gb and supports a range of gases with specific SI levels, including ammonia, chlorine, hydrogen chloride, carbon monoxide, and more.

Approvals and Certifications: The device is certified under DIN EN 61508-2: 2011 for functional safety and is suitable for use in various gas detection applications.
