(+VH) and sensing layer (+ Vs). Figure 1. MGS1100 CO Sensor Cross-Sectional Schematic (Top View) The MGS1100 is manufactured under license from MicroSens, Neuchatel, Switzerland.
Table 1. Absolute Maximum Ratings? Table 2. Recommended Electrical Operating Limits2 Table 3. Sensitivity Characteristics3 Caution: Heater voltage ramp not to exceed 0.5 V/msec. Pre—-Condition: 48 hours (min) in clean air with Recommended Operation. Environment: Synthetic air, 50 +5% RH, 22 +3°C.
- The following specifications apply to the MGS1100 CO sensor and are subject to change to accommodate continuous improvement.
- The heater voltage and power must be observed and limited as described in Table 1. Permanent damage may occur if the maximum power
- Response time is defined as the time for the incremental change in the output when subjected to a 100 ppm CO step change.
