Structure and Dimensions:
Standard Circuit Conditions:
Pin Connection and Basic Measuring Circuit:
The numbers shown around the sensor symbol in the circuit diagram at the right
correspond with the pin numbers shown in the sensor's structure drawing (above.
When the sensor is connected as shown in the basic circuit, output across the Load
Resistor (V
RL
) increases as the sensor's resistance (Rs) decreases, depending on
gas concentration.
Sensor Resistance (Rs) is calculated by
the following formula:
C
RL
Rs = ( V
L
Power dissipation across sensor electrodes (Ps)
is calculated by the following formula:
Ps =
