LM35: 温度センサー出力が通常の5倍程度になる

Part Number: LM35


  • Dear Kido - 

    Thanks for the post and welcome to E2E. If possible, in the future, please post in English.

    For your inquiry - 

    The case of that package variant is connected to GND, so the metal it is making contact with must be at a different potential. 

    Please see or use the LP package if plastic encapsulated version works better for your application. 

  • LM35AH is used for production line equipment
    If the metal part of the unit where the LM35AH is mounted touches the metal part of the device while the motor of the device is operating, the output of the temperature sensor will increase about 5 times.
    Do you have resin type products for TO-46 package?
    If not, please teach me how to do it
    The output of LM35AH is amplified by an operational amplifier.
    Amplification resistance is adjustable with volume
    Thank you

  • Yes, that is more or less what I translated and answered, above, thanks!
