GfG ZD22 Oxygen Fixed Transmitter ZD22-701_
GfGs ZD 22 transmitter is a cost effective transmitter for detecting oxygen, but without the need for explosion protection. Due to the different types of signal transmission, the ZD 22 can be connected to almost any gas detecting system, also as a supplementary measuring point or replacement transmitter on existing systems. The ZD 22 is a powerful transmitter for the detection of oxygen, using an amperometric sensor based on an electrochemical zirconium dioxide oxygen pump cell. The detection principle features good long term stability and selectivity. A particularly long sensor life makes the ZD22 a low cost transmitter for oxygen monitoring. The expected lifetime of the sensor is 5 or more years in continuous operation. In the event of an alarm, the display will turn red and an acoustic signal will be given.
