Toxic gas gas transmitter TOX 914 LON®

electrochemicalfor ambient airconcentration

The gas measurement sensor ADOS TOX 914 LON® is suitable for the continuous measurement of the concentration of toxic gas in air. Fields of Application In garages for measurement, control and warning purposes, the TOX 914 LON®, in conjunction with the FlexADOS 914 LON® fulfils the VDI guideline 2053 from December 2014 and also EN 50271:2011 For ambient air monitoring of occupational exposure limit values (German: AGW value) e.g. in laboratories or motor test stands In private and collective shelters to monitor external or internal air Function Example, CO-sensor The ADOS TOX 914 LON® CO gas measurement sensor uses a method where the air to be measured is diffused into a chemical measuring cell. The H+ ions and electrons released at the electrode are consumed in a cathode reaction. The low of current between anode and cathode generated during this process is directly proportional to the CO concentration in the measured air. The sensor current is amplified and applied via the LON® field bus of an evaluation unit e.g. FlexADOS 914 LON®, where the measured variable is processed and displayed in ppm CO together with any possibly necessary control and warning functions.
