GfG Instrumentation 2801-20-002 CC28 Series Fixed Transmitter with Gas Optimized Catalytic Sensor, Ammonia, Display, 0-4% Vol. Range

Flammable gases in Ex zones safely under control

If flammable gases and vapors need to be monitored in Ex zones, the CC28 D transmitter is a reliable and economical solution. The CC28 D uses analog signals (4-20 mA) to provide measured values and status information. Readings are also shown on the display on site. The special stack effect ensures very short response times of only a few seconds for fast warning of explosion hazards. In combination with GfG's reliable controllers, it can be installed in new gas detection systems or retrofitted into existing ones.

The CC28 D uses catalytic combustion (CC) to detect combustible gases and vapours. While in operation, its 2.2-inch display indicates the current measured value and will  light up red in the event of an alarm. The long-life sensors make the CC28 D an economical solution for detecting Ammonia in the measurement range 0-4% volume. Its automatic temperature compensation and the linearization of the measurement signals ensure high measurement accuracy.

Functional safety and device protection

The CC28 D is ATEX certified for use in Ex Zone 1 and its hardware complies with the European Functional Safety Standard DIN EN 61508-2: 2011 (SIL). The housing is protected against ingress of dust and water (protection class: IP64). An optional weatherproof housing provides additional protection.

Communication and service

Signals are transmitted via the analog industry standard (4 to 20 mA). The CC28 D uses two status LEDs to indicate its operating status. Service and settings are performed intuitively on site using three buttons directly on the device (one-person adjustment). The pre-adjusted sensors can be easily replaced thanks to Smart Sensor technology. The multicolor backlit display shows the current measured value, status messages and the CC28 D menu. Test gases for function tests can be inserted using a flow adapter.
