The hardware of the EC28 DA 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. Adjustments can be made using the RC2 remote control (one-man calibration).
Display, Control Buttons and Alarms
The EC28 DA 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. The EC28 DA has highly visible, red alarm LEDs and a loud, integrated horn (90 dB). Costs for additional, ex-protected alarm devices can therefore be eliminated.
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.
