CC33 Fixed Transmitter, stainless steel, for very demanding applications, by GfG Instrumentation

CC33 transmitter with stainless steel enclosure, for flammable gases and vapors with ignition protection type "d".

If flammable gases and vapors need to be monitored safely in Ex zones under demanding conditions such as in the food industry, the CC33 transmitter with its unpainted stainless steel housing is an extremely robust and reliable solution. The CC33 transmits 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 its LC display. The special stack effect ensures very short response times of only a few seconds for a quick warning of explosion hazards. Three relay outputs provide additional alarm options. In combination with GfG's reliable controllers, it can be installed in new gas detection systems or retrofitted into existing ones.

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). The CC33 is also able to utilize ACDC technology, which enables it to transmit digital data on analog, three-wire lines in systems using an ACDC-capable controller. It uses two status LEDs to indicate its operating status and also features two additional alarm LEDs and three relay LEDs. Service and adjustments can be carried out on site with a magnetic pen and three magnetic buttons behind 15 mm thick bullet-proof glass (one-person adjustment). The pre-adjusted sensors can be easily replaced thanks to Smart Sensor technology. The multi-color backlit display shows the current measured value, status messages and the CC33's menu. Test gases for function tests can be inserted using a calibration adapter. Alternatively, when the device is mounted in a difficult-to-reach location, an optional remote calibration adapter can be used without impairing the transmitter's stack effect.

Explosion and device protection

The CC33 is approved for use up to Ex zone 1 and meets the requirements of ignition protection type "d" (flameproof enclosure). The unpainted stainless steel housing and Viton seals guarantee a long operating time even in the toughest conditions. The transmitter is protected against the ingress of dust and water according to IP54. If required, the protection class can be raised to IP67 with additional thread seals. For any applications not requiring a stainless steel housing, the CC33 is also available in a painted aluminum housing.
