Fuel gas transmitter CC28 D

catalyticfor environmental measurementswith display

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 such as methane, propane and hydrogen. 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 a wide range of combustible gases in the measuring ranges of 0 to 100 % LEL and 0 to 4 % by volume (NH3). 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).
