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's 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. Smart Sensor technology allows for quick and easy sensor replacements and the RC2 remote control can be used to make adjustments (one-person calibration).
RC2 remote control (optional)
Gases like ammonia and hydrogen are lighter than air. Transmitters to detect them are therefore installed near the ceiling. To facilitate service and maintenance work, they can be equipped with a permanently installed cable which can be connected to an RC2 remote control. This lets you access the transmitter from ground-level at all times, making inspection, calibration or maintenance work significantly easier.
Reliable Measurement & Minimal Operating Costs
The sensor and built-in temperature compensation guarantee high measuring accuracy. The long sensor service life and low maintenance requirements ensure minimal operating costs.
