Other Parts Discussed in Thread: LMP91000, LMP90100

Hello, I am trying to evaluate the performance explosive sensor

http://www.sgxsensortech.com/site/wp-content/uploads/2012/10/VQ548ZDW.pdf

have the module lmp91000 but it cant use these sensors.

http://www.ti.com/ww/en/more/solutions/chemical.shtml

I'm looking to use a pg309

http://www.ti.com/ww/en/industrial/sensors/pressure/design.html

The manufacturer suggests the following scheme sensor

Can suggest any parts for the bridge circuit ?
And for to compensate the temperature?


Best regards

    Hi Juan,

    the explosive sensor you are evaluating is not managed by the LMP91000. The explosive sensor is not an electrochemical cell, it is a pellistor, so you need a completely different front end (bridge read out circuit).

    regards,

    Domenico

    Hi Domenico

    I know this is a  pellistor sensor that we agree.

    But what I was trying to say was if a suitable module for using SPIO-4 board. I was thinking about buying the lmp90100 module for this purpose. I wonder if it is correct to use this module to said sensor explosive.

    regards Juan
