TECHNICAL INFORMATION FOR TGS2610

2-7   Long-term characteristics

Figure 13 shows long-term stability of TGS2610 as
measured for more than 900 days.  The sensor is first
energized in normal air.  Measurement for
confirming sensor characteristics is conducted under
standard test conditions.  The initial value of Rs was
measured after two days energizing in normal air at
the rated voltage.  The Y-axis represents the sensor
resistance in air, 3500ppm of methane, 1500ppm of
iso-butane, and 3500ppm of hydrogen.

The Rs in iso-butane is very stable over the test
period.

Figure 14 shows the influence of storage in an
unenergized condition on the sensor’s resistance.  The
sensors were stored unenergized in air after 20 days
energizing, then energized for one hour before a
measurement was taken.

As the charts presented in this section illustrate, the
sensor shows stable long term characteristics.

NOTE:
The MTTF (Mean Time to Failure) can be estimated
from this data.  Please refer to the Technical Advisory
MTTF Values of Figaro Gas Sensors.
