EC28 D Transmitter

Ex-compliant with Display for Toxic Gases, O2 and H2


Whenever toxic gases, hydrogen or oxygen are to be monitored and current measured values are to be displayed locally, the EC28 D transmitter combined with GfG‘s proven control units is the solution of choice. The ATEX-certified design means it can be used even in potentially explosive atmospheres.

Functional Safety
The hardware of the EC28 D 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 are listed in the overview of gases.

Communication and Service
Communication is carried out via a 4-20 mA signal. The Smart Sensor technology enables fast and uncomplicated replacement of the sensor.

Display and Control Buttons
The EC28 D 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. In addition, the operating parameters (sample gas, measuring range, limit values, etc.) can be called up via the operating keys.

Remote Control RC2 (optional)
If the EC28 D has to be mounted in a difficult-to-access location, the RC2 remote control facilitates servicing and adjustments (one-man 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 ensure the highest measuring accuracy. The long sensor service life and low maintenance requirements ensure minimal operating costs.
