High Temperature Transmitters

    Hi,

    I'm looking for a high temperature transmitter/switch that has an operating range of up to +500 °C. I found a TURCK option but it is $300. Do you have any cheaper recommendations?

    Thank you in advance for any help.

    What instrument is it connecting in to? You mention transmitter or switch - they are 2 very different things so we'd need to know which you want.

    What signal do you require - 4-20ma? 0-10 volts? Could you use a thermocouple?

    The one you linked says "Pt-100", a few times, that's a common type of RTD and can be had for less than £50 but 500 degrees is about the limit of their working range, a thermocouple would probably be better suited (And cheaper).

    The linked ones are transmitters - they use an rtd but convert the signal to a milliamp/voltage output.

    It'd be good to know what it's connecting in to - quite often an instrument will measure an rtd or thermocouple directly so there may be no need for a transmitter - or alternatively if you need it converting it will be cheaper to buy a stand alone signal conditioner and probe. Without knowing exactly what else is being used though it's all just guessing.
