LMP91000: Wiring LMP91000 to SPEC Sensor

Juan Ortega

Part Number: LMP91000

Tool/software:

Hello,

I wanted to ask a question about the LMP91000 AFE. I have a SPEC Sensor like this one: Nitrogen-Dioxide-Sensor-110507_110508_110509_1.pdf (spec-sensors.com)

I saw that it has two working pins, can I wire them together so I can connect the sensor to the AFE?

Thank you very much for your help.

    Juan,

    I'm not sure they can wired together. Do you think it's possible that they are duplicate pins, so two different AFEs could be connected, one to each working electrode? I would first try to see if they output the same current levels. We do have some recommendations on using a 4-lead chemical cell, but those usually have an "aux" pin as the 4th, not another working electrode pin.

    Regards

    I think they are duplicated pins. I have asked the manufacturer of these sensors to check. I will update this thread as soon as I have answers
