CC28 DA Transmitter

If you need to monitor combustible gases and vapors in potentially explosive areas, the CC28 DA transmitter is a great, safe choice. It is approved for use in Ex zone 1.

The smart sensors are pre-calibrated, reducing the amount of service work when replacing a sensor. The durable sensors (5-year operating life) the Catalytic Combustion method to measure gases. The sensor housing’s chimney effect ensures very quick reaction times.

The CC28 DA uses a 4-20 mA output signal to transmit the current measured value to the central controller, which then evaluates the signal and initiates safety measures in case of alarms. Its hardware fulfills the European Norm for Functional Safety DIN EN 61508-2: 2011 (SIL) and its housing is well protected against the ingress of dust and water (protection class IP64).

The backlit display shows the measured value in alternation with the type of gas. In case of alarms, red LEDs above the display and an integrated buzzer will give a visual and audible warning signal respectively.
