My brain is scrambled after a busy day at work and cannot be bothered to go into detail.

To set you on your way, that kind of detector is known as a pellistor.
You will need two resistors to complete a bridge circuit which you can then connect to your instrument amplifier.

Have a look here:

see if that helps.

Signal conditioning help!!!!

Hi,

I have to design gas detector circuit for explosive gases.

As per mentioned in datasheet, the sensor output is 27 ± 5 mV / % methane.

I need some advice regarding amplification of this signal.

There is a requirement of potentiometer for zero adjustment.

Please suggest.

Thanks,
paddy
 
What part, and link for data sheet please.
You can use an op amp with amp the signal to what you require it to be at
