EC28 DA Transmitter
With Display and Alarm for Use in Ex Zones
Whenever toxic gases, oxygen or hydrogen need to be monitored and you want a display of the current measured value as well as an alarm to be given on site, the EC28 DA transmitter is the best choice - especially when combined with GfG‘s reliable controllers. The ATEX-certified design means it can be used even in potentially explosive atmospheres.
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 DA's communication works on a 4-20 mA signal basis. The Smart Sensor technology enables fast and uncomplicated replacement of the sensor. Adjustments can be made using the RC2 remote control (one-man calibration).
Display, control buttons and alarms
The transmitter is controlled via 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. The EC28 DA has highly visible, red alarm LEDs and a loud, integrated buzzer (90 dB). Any costs for additional, ex-protected alarm devices can therefore be eliminated.
Reliable measurement & minimal operating costs
Its sensor and the built-in temperature compensation guarantee the highest measuring accuracy. The long sensor service life and low maintenance requirements ensure minimal operating costs.
