Figure 2 shows the variation

in sensitivity caused by

changes in temperature.

See Application Note:

AAN 110 on our website

Figure 4 shows the time taken

for a typical O2-E2 sensor to

reach 90% of its maximum

output. This is termed the t

90

response time and for these

sensors is less than 10

seconds.

For further information on the performance of this sensor, on other sensors in the range or any other subject, please

Figure 4 Response Profile

Step changes in pressure can

cause a temporary signal

transient. Positive pressure

gives an output signal

increase whilst negative

pressure causes the output

signal to decrease.
