EC28 D Transmitter
Ex-compliant with Display for Toxic Gases, O2 and H2
Whenever toxic gases, hydrogen or oxygen need to be monitored and you want the current measured values to be displayed locally, the EC28 D transmitter combined with one of GfG‘s reliable controllers is the best 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 D's communication works on a 4-20 mA signal basis. The Smart Sensor technology ensures 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. The operating parameters (sample gas, measuring range, limit values, etc.) can be also be called up via the intuitive control keys.
Remote control RC2 (optional)
If the EC28 D has to be installed in a difficult-to-access location, the RC2 remote control facilitates servicing and adjustments (one-person adjustment). The information it displays is identical to the one shown on the transmitter‘s display.
Reliable measurement & minimal operating costs
Its sensor and built-in temperature compensation ensure the highest measuring accuracy. The long sensor service life and low maintenance requirements ensure minimal operating costs.
