Transmitter CC33

Product catalog summary

Overview: The CC33 Transmitter is designed for monitoring combustible gases and vapors in hazardous areas, specifically Ex zone 1. It features a flameproof enclosure and utilizes catalytic combustion for rapid detection of flammable gases.

Specifications: The transmitter operates with a measuring range of 0 to 100% LEL and 0 to 4 vol% for ammonia. It supports both diffusion and gassing via a calibration adapter. The sensor has a lifespan of approximately 5 years, with a response time of t90 ≤ 9 seconds. It functions within a temperature range of -25 to +55 °C, humidity of 5 to 95% r.h., and air pressure of 80 to 120 kPa. The output signals include analog (4-20 mA) and digital (RS-485), with a power supply requirement of 12 to 30 V DC.

Design and Construction: The CC33 is available in a die-cast aluminum housing with IP67 protection class. It measures 145 x 169 x 129 mm and weighs 1.60 kg. The device is certified for types of protection II 2G Ex db IIC T6 Gb and II 2G Ex db ib IIC T4/T6 Gb, suitable for temperatures between -20 °C and +55/+40 °C.

Features: The transmitter includes a color backlit 2.2-inch display for reading measurements and menu navigation using a magnetic pen. It has four colored LEDs for status indication. Optional features include a buzzer for audible alarms and three programmable relays for additional alarm devices.

Applications: The CC33 can be used as a standalone solution or in combination with GfG controllers for monitoring flammable gases like methane, butane, or propane, and ammonia. It is suitable for environments requiring early hazard detection and control of alarms and safety measures.

CC33 Transmitter Flameproof enclosure for explosive gases and vapors in Ex zone 1 If combustible gases and vapors are to be monitored in hazardous areas and there is a requirement for a flameproof gas detector, the CC33 transmitter is a reliable solution. It meets the requirements of ignition protection type „d” for safe use in Ex zone 1. Thanks to the proven measuring principle of catalytic combustion, the CC33 detects flammable gases with shortest response times (t90 < 9 s; sensor dependent). This is due to the chimney effect of the sensor housing, which ensures a faster gas flow. Connection...
