Intrinsically safe operation
Due to its intrinsically safe build, the EC28 Di can be used even in areas with a particularly high risk of explosion. A safety barrier (SB1 or Zener barrier; optionally available) has to be connected between the transmitter and the programmable logic controller (PLC) to convert the supply voltage to 24 V DC. This prevents the power lines from igniting within the Ex zone. The intrinsic safety of the EC28 Di is ATEX-certified and makes it suitable for applications up to Ex zone 0.
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.
Display and Control Buttons
The EC28 Di 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.
Remote Control RC2 (optional)
If the EC28 Di has to be mounted in a difficult-to-access location, the RC2 remote control facilitates servicing and adjustments (one-man adjustment). It displays the
same information that is shown on the transmitter‘s display.
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.
