TECHNICAL INFORMATION FOR TGS2610
2-3 Heater voltage dependency
Figure 8 shows the change in the sensor resistance
ratio according to variations in the heater voltage
(VH).
Note that 5.0V as a heater voltage must be maintained
because variance in applied heater voltage will cause
the sensor’s characteristics to be changed from the
typical characteristics shown in this brochure.
2-4 Circuit voltage dependency
Figure 9 shows the change in the sensor resistance
ratio resulting from variation in circuit voltage (Vc).
As shown here, using a Vc higher than the 5.0V
specified in Section 1-5 may result in the sensor
diverging from Ohmic behavior and thus altering its
characteristics from those shown as typical in this
brochure.
