Fixed Gas Detection Systems Long-term monitoring of oxygen

ZD22 Transmitter Long-term monitoring of oxygen Overview of available measuring ranges and SIL: The ZD22 was developed especially for long-term monitoring of the oxygen concentration. The ZD22 uses a sensor based on a zirconium dioxide (ZD) electrochemical oxygen pump cell. Selectively for oxygen, the ZD sensor is insensitive to ambient conditions as well as sensor poisons and convinces at the same time with very short response times. The hardware of the ZD22 complies with the European Functional Safety Standard DIN EN 61508-2: 2011*. Thus, hardware SIL2 is possible in single-channel use (1oo1)...
