Transmitter CC28

Product catalog summary

Overview: The CC28 Transmitter is designed for monitoring combustible gases and vapors in hazardous areas, particularly Ex zones. It is a reliable and economical solution when used with GfG's controllers, offering fast response times for gases like methane and propane.

Specifications: The transmitter 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 for easy sensor replacement, and test gas can be added via a calibration adapter. An optional RC2 remote control simplifies maintenance, especially for ceiling-mounted transmitters.

Reliability and Cost Efficiency: The CC28 offers rapid detection and high measurement accuracy due to built-in temperature compensation. It has low maintenance requirements and a long sensor service life, minimizing operating costs. Sensor wear is reduced by automatic shutdown at 112% LEL.

Variants: The CC28 is available in several versions: the basic version, CC28 D with a display, and CC28 DA with a display, LED warning lights, and an alarm buzzer. These variants cater to different application needs.

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 housing is plastic and antistatic, with a protection class of IP64.

Approvals and Certifications: The CC28 holds ATEX labeling and EC Type Examination Certificates for electric explosion protection and measuring function. It meets EMC standards and has radio shielding and interference resistance classifications.

Gas Detection Capability: The transmitter can detect a wide range 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.
