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.
This repeatability was tested
on sensors six months old.

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.
