EC28 DB Transmitter

Ex Zone Monitoring with Display and Modbus

Whenever toxic gases, hydrogen or oxygen need to be monitored and you want current measured values to be displayed locally as well as transmitted digitally, the EC28 DB transmitter combined with one of GfG‘s reliable controllers is the perfect solution. The ATEX-certified design means it can be used even in potentially explosive atmospheres.

Functional safety
The EC28 hardware complies with the European Functional Safety Standard DIN EN 61508-2: 2011 for many gases. The SI levels (up to SIL3) in single channel (1oo1) or redundant (1oo2) use depend on the gas type and the sensor.

Communication and service
The EC28 DB's communication works via RS-485 industry standard with Modbus protocol. The Smart Sensor technology allows for quick and easy replacement of the sensor.

Display and control buttons
The transmitter features a 2.2 inch LC display and three control buttons. In normal operation, the display shows the measured value or information on faults or alarms. The operating parameters (sample gas, measuring range, limit values, etc.) can also be called up using the intuitive button controls.

RC2 remote control (optional)
If the EC28 DB has to be mounted in a difficult-to-access location, the RC2 remote control facilitates servicing and adjustments (one-person adjustment). It displays the same information that is shown on the transmitter‘s display.

Reliable measurement & minimal operating costs
The sensor and built-in temperature compensation guarantee the highest measuring accuracy. The long sensor service life and low maintenance requirements ensure minimal operating costs.
