In solid state sensor, when heated to 150o to 300o which of the following occurs?
A. Resistance decreases with increase in H2S concentration
B. Resistance increases with H2S concentration
C. No change in resistance occurs
D. Sensor does not respond in this temperature range
Answer:A
In solid state sensor, when heated to 150o to 300o which of the following occurs?
A. Resistance decreases with increase in H2S concentration B. Resistance increases with H2S concentration C. No change in resistance occurs D. Sensor does not respond in this temperature range
Explanation: In solid state sensor, when heated to 150o to 300o resistance decreases with increase in H2S concentration. The decrease in resistance is a logarithmic function of H2S concentration.
