If toxic and flammable gases and vapors need to be monitored outside Ex zones, the CS22 D transmitter is a reliable and economical solution. The CS22 D transmits measured values and status notifications on an analog (0.2-1 mA or 4-20 mA) or digital (RS-485) signal, while also displaying them on site. In the event of an alarm, it will warn everyone in the vicinity using its internal buzzer. In combination with GfG's reliable controllers, it can be installed in new gas detection systems or retrofitted into existing ones.
The CS22 D uses chemisorption (CS) to detect flammable and toxic gases such as ammonia, methane and numerous refrigerants. The current measured value is indicated on the 2.2-inch display, which lights up red in the event of an alarm. The long-life sensors make the CS22 D an economical solution for detecting a wide range of gases in measuring ranges such as 0 to 5,000 ppm, 0 to 100 LEL or 0 to 1 % by volume. Its automatic temperature compensation and the linearization of the measurement signals ensure high measurement accuracy.
Functional safety and device protection
The hardware of the CS22 D complies with the European Functional Safety Standard DIN EN 61508-2: 2011 (SIL). The housing is protected against the ingress of dust and water (protection class: IP54). An optional weatherproof housing provides additional protection.
Communication and service
Signals are transmitted via the analog industrial standard (optionally 0.2-1 mA or 4-20 mA) or the digital RS-485 interface (Modbus protocol).
