APPLICATION NOTES FOR TGS2611

Figure 10 - Pre-calibrated sensor module NGM2611

result, Figaro neither expressly nor impliedly
warrants the performance shown in Figure 9. If
a large difference between the expected and
actual performance of detectors is noticed, please
consult with Figaro.

Pre-calibrated sensor module

Figaro has available a pre-calibrated methane
sensor module NGM2611 (

see Fig. 10

). This

module includes the classified TGS2611 sensor,
a matched load resistor, and a factory preset
temperature compensation circuit, all on a small
PC board.  The NGM2611 module is calibrated
for a typical set point at 10% LEL, achieving
performance as indicated in Figure 9  by simply
plugging it into a main PC board.  Please refer
to the brochure “

Product Information for

NGM2611

” for detailed information.

Important Reminder

Without testing alarm threshold after final assembly,
detectors have no accuracy or reliability guarantee.
