TECHNICAL INFORMATION FOR TGS2610
3-2  Gas exposure test #2
Figure 18 shows the effect on TGS2610 of a high
concentration of ethanol vapor on sensor
characteristics.
Sensors were energized and their resistance prior to
ethanol exposure was measured.  The sensors were
then placed in a 10% concentration of ethanol for 20
hours.  After this exposure, the sensor was energized
in normal air for 1 hour prior to measuring sensor
resistance.  After an additional 1 day of energizing,
the sensor resistance was measured again.
As this data would suggest, sensor characteristics
remain largely unaffected after exposure to a high
concentration of ethanol.
3-3  Corrosion test  (*)
Figure 19 shows the effect on TGS2610 of corrosive
gases specified in Item 43.15 of the UL 1484 standard.
Sensor resistance prior to corrosive gas exposure was
measured.  Unenergized sensors were then placed
into an environment of 23˚
±
2˚C and 95%RH.  In this
environment, two separate tests were conducted: one
in 0.1% H
2
S, the other in a combination of 0.5% SO
2
and 1.0% CO
2
, with each test exposure lasting 10
days.  After this exposure, the sensor was re-
energized in normal air prior to measuring sensor
resistance after removal from corrosive gases.
As this data would suggest, sensor characteristics
remain largely unaffected after exposure to corrosive
gas concentrations specified by Sec. 43.15 of UL 1484.
3-4  Ignition test (*)
TGS2610 has been successfully tested against the
ignition test requirements of the UL1484 standard.
The sensor did not initiate ignition of a propane
concentration of 5.25% by volume.
