Toxic gas electrochemical sensor TOX 592

4-20 mA

The ADOS TOX 592 gas sensor is suitable for continuous measurement of a concentration of toxic gas in air, over the range of 0-20 ppm to 0-1000 ppm. Field of Application - In garages for measuring, control and warning, in conjunction with the ADOS Multitronik 592 tested to VDI 2053 standards For monitoring at working places, to control the maximum concentration value e.g. in laboratories or motor test stands In private and collective shelters for monitoring the external or internal air Function Example, CO-sensor The ADOS TOX 592 CO gas sensor uses a method of measurement where the air to be measured is diffused in a chemical measuring cell. The (H+)-ions and the electrons released, are consumed at the electrode in a cathode reaction. The flow of current between anode and cathode, generated by this process, is directly proportional to the CO-concentration in the measured air. The sensor current is amplified and applied via a 4-20 mA field-bus to an evaluation unit, e.g. FlexADOS 914 CP, where the measured variable is processed and indicated in ppm CO, together with any control and warning functions which may be necessary.
