Compur Statox 4120 1. Important notice Statox 4120 is an explosion proof system for the detection of toxic gases. It can be operated in hazardous areas classified division 1 and 2. Before installing and putting Statox into operation read and observe this manual! To operate the system safely, observe this manual carefully. It must be operated and maintained by qualified and authorised personnel. No other application than ambient air monitoring of the gas specified is aut

Compur Statox 4120 pic. 2: Statox 4120 sensor head for Cl und ClO 2 2 Operation principle Ambient air enters the sensor (2) by diffusion through an opening at the bottom. The sensor creates a current - signal proportional to the gas concentration. This signal is amplified, temperature compensated and linearised. As a digital signal it is transmitted to the control module. To protect the sensor from being poisoned by a high gas concentration, the Statox features a built
