EC28 Transmitter
For Toxic Gases, O2 and H2 in Ex Zones
Whenever toxic gases, oxygen or hydrogen need to be monitored, the EC28 transmitter combined with one of GfG‘s reliable controllers is a perfect, cost-effective solution. This ATEX-certified transmitter guarantees safe use, 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's communication works on a 4-20 mA signal basis. The Smart Sensor technology enables quick and easy replacement of the sensor. Adjustments can be made using the RC2 remote control (one-person calibration).
Remote Control RC2 (optional)
Gases like ammonia and hydrogen are lighter than air. Transmitters with these sensors are therefore installed near the ceiling. To simplify servicing, these transmitters can be equipped with a permanently installed cable meaning that the RC2 remote control can be connected for maintenance work and any adjustments can be made from ground level. The display of the RC2 remote control shows the same information as would be shown by the EC28 versions with display. This makes inspection, maintenance and calibration much easier.
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.
