Transmitter CC28 DA

Product catalog summary

Overview: The CC28 DA Transmitter is designed for monitoring combustible gases and vapors in hazardous areas. It features a display, LED alarm lights, and a buzzer, providing a reliable and economical solution when used with GfG's controllers. The transmitter offers short response times, ensuring quick warnings for gases like methane and propane.

Specifications: The device is ATEX certified with ignition protection types 'd' (flameproof enclosure) and 'e' (increased safety), suitable for Ex zone 1. It complies with the European Functional Safety Standard DIN EN 61508-2:2011. The detection principle is catalytic combustion, with detection ranges from 0 to 100% LEL and 0 to 4 vol% for ammonia. The expected sensor life is 5 years, with a response time of t₉₀ ≤ 9 seconds.

Communication and Service: Signal transmission follows the 4–20 mA industry standard. The Smart Sensor technology allows easy sensor replacement, and a calibration adapter facilitates test gas addition. An optional RC2 remote control is available for adjustments in hard-to-reach locations.

Display and Alarm Features: The CC28 D transmitter includes a 2.2-inch LC display and three pushbuttons. It shows measured values, faults, or alarms and allows access to operating parameters. The device has red LED alarm lights and a 90 dB buzzer, reducing the need for additional Ex-protected alarm devices.

Reliability and Cost Efficiency: The stack effect ensures rapid detection of gases, allowing time for countermeasures. Temperature compensation enhances measurement accuracy, while low maintenance and long sensor life minimize operating costs. Automatic shutdown at 112% LEL reduces sensor wear.

Variants: The CC28 is available in several versions: the basic version for various flammable gases, the CC28 D with a display, and the CC28 DA with display, LED warning lights, and alarm buzzer. All versions are compatible with GfG's high-performance controllers.

Technical Data: Operating temperature ranges from -20 to +50 ºC in Ex zones and -25 to +55 ºC outside Ex zones. Humidity tolerance is 5 to 90% r.h., and air pressure ranges from 80 to 110 kPa in Ex zones. The device weighs 800 g and measures 100 x 193 x 55 mm.

Approvals and Certifications: The CC28 DA holds ATEX labeling and EC Type Examination Certificates for electric explosion protection and measuring function. It meets Functional Safety (SIL) standards and EMC requirements.

Gas Detection Capabilities: The transmitter can detect a variety of gases, including acetone, acetylene, ammonia, carbon monoxide, diethyl ether, ethane, ethanol, ethyl acetate, ethylene, hexane, hydrogen, isopropanol, methane, methanol, n-nonane, n-butane/isobutane, natural gas, propane, propyne, propylene, and toluole.
