Sensing resistance in air R0 is measured under controlled ambient conditions, i.e. synthetic air at 23 ±5°C and 50 ± 10% RH. Sampling test. 2. Sensitivity factor is defined as Rs in air divided by Rs at 60 ppm CO.

The resulting voltage is typically VH = 2.4V. The voltage measured on the load resistor is directly linked to the resistance of the sensor respectively. RLOAD must be 820 Ω at the lowest in order not to damage the sensitive layer. Power circuit and measurement circuit R is a 82 Ω.

The sensors are placed in a carrier type. The dimensions of the cavity are 5.5 x 7.5 x 2.55 mm (the tolerance is +/- 0.2 mm). The outside dimension of the reel is either 178 +- mm (for a maximum of 700 sensors ) or 330 + 0.
