TECHNICAL INFORMATION FOR TGS2610
2. Typical Sensitivity Characteristics
2-1   Sensitivity to various gases
Figures 4a and 4b show the relative sensitivity of
TGS2610 to various gases.  The Y-axis shows the ratio
of the sensor resistance in various gases (Rs) to the
sensor resistance in 1800ppm of iso-butane (Ro).
For TGS2610-C, the sensitivity to ethanol, which may
act as an interference gas, is lower compared with
that of iso-butane/propane. However, TGS2610-D
shows significantly less sensitivity to alcohol than
TGS2610-C while showing no significant difference
in sensitivity to iso-butane/propane.
Using the basic measuring circuit illustrated in Fig. 2,
and with a matched R
L
 value equivalent to the Rs value
in 1800ppm of iso-butane, will provide the sensor
output voltage (V
RL
) change as shown in Figure 5.
NOTE
:
All sensor characteristics in this technical brochure
represent typical sensor characteristics.  Since the Rs
or output voltage curve varies from sensor to sensor,
calibration is required for each sensor (for additional
information on calibration, please refer to the Technical
Advisory ‘Technical Information on Usage of TGS Sensors
for Toxic and Explosive Gas Leak Detectors’
).
