• 【问】一块板上用4个AD8497接4路热电偶测温, 如下电路图

    【问】我在一块板上用4个AD8497接4路热电偶测温,AD8497输出端是接到AD. 正常情况下如果我断开其中一路热电偶,其他三路的电压会有很大变化,这是为什么?

  • AD8494 - remote cold junction sensing

    Hi, 

    I am planning to use the AD8497 K-type thermocoupler amplifier to read temperature. But, the AD8497 will not be any near the thermocoupler cold-junction, in fact, it will be on separate board, becouse of high temperature that i have to measure.There…

  • RE: AD8496 for K-Type Thermocouple temperature sensing

    JonathanNardar,

    Thank you for reaching out to us for your application.
    It is advisable to use the AD8495 or AD8497 because this is specifically trimmed to optimize the linear operating range of the K-Type thermocouple.
    The transfer function and nonlinearity…

  • RE: 请问采用K型热电偶的温度测量信号如何采集?

    根据需要的冷端补偿温度范围选择AD8495(0°C to 50°C)或AD8497(25°C to 100°C)。

  • RE: AD8495 cryogenic temperatures error

    I also trying to compare the results of the transfer function with the Type K Vtc values, but is not mat

    With the voltage from Table 3 from AN-1087 (Thermocouple Linearization When UAD8495/AD8496/AD8497).

    But the results do not match.

    Also would I…

  • RE: Type T thermocouple signal conditioner

    Hi Michael,

    Yes, the AD595 can be used for the T type thermocouple because of it has a similar range with the K type thermocouples  and you can see detailed discussion here: https://ez.analog.com/docs/DOC-13253

    However, we have newer/alternative part…

  • RE: thermocouple amplification

    thank you krisf for your reply...For my application AD8497 because of the temperature range. if am i using 10 number of thermocouples, can i use any analog multiplexer in between thermocouple and amplifier for a such low thermocouple voltage, or i need…

  • RE: Ambient temperature of AD8495

    Hi Akira,

    I need to check if we have data or calculation how much Ambient Temperature Rejection spec will change once you operate outside the specified ambient temperature range.  Just an additional info from the older thread:  "The AD849x thermocouple…

  • RE: Reading thermocouple correctly with a 2 ground connections.

    Wallace,

    The AD597 is inherently an instrumentation amplifier. So it will reject the difference between your two grounds as long as you run an isolated pair of thermocouple wires from your thermocouple into your circuit board. Run the thermocouple wires…
