Gasoline vapor gas transmitter CC33

If you need to safely monitor combustible gases and vapors in Ex zones, the CC33 transmitter is an extremely durable and reliable solution - even in demanding conditions, such as in industrial production plants. The CC33 can communicate its measured values and status indications either on analog (4-20 mA) or digital (RS-485) signal. The current measured gas concentration is also shown on an LC display. Due to the special stack effect, the response times of the CC33 are very short which ensures quick warnings in case of explosion hazards. Three relay outputs provide additional alarm options. In combination with one of GfG’s reliable controllers, the CC33 can either be installed in a new gas detection system or retrofitted into an existing one. The CC33 uses catalytic combustion (CC) to detect flammable gases and vapors such as methane, propane and hydrogen as well as ammonia. Their long-life sensors make 33 series transmitters an economical solution for detecting a wide range of combustible gases in the measuring ranges 0 to 100 % LEL and 0 to 4 % by volume (NH3). Its automatic temperature compensation and the linearisation of the measuring signals ensure high measuring accuracy. In the event of an alarm, two red LEDs light up and the display color changes to red. The three optional relay outputs can be used to automatically trigger an explosion-proof buzzer, visual warnings such as flashing lights or the ventilation in case of an alarm. Communication and service Signals are transmitted on the analog industrial standard (4-20 mA) or via the digital RS-485 interface (Modbus protocol).
