Sensor input data for Thermocouple Gauge Tubes 531

Guys, I didn't find the sensor input data in the agilent gauge 531 data sheet (there is only output)
and the only information that exists is 165ma with 15ons, the question is:
- What is the power supply voltage for input?
- What is the supply current for input?

  • Hello Dahulett!
    Thank you very much for sharing the document.
    But I need to know what the sensor's power supply is in Volts? 3V, 5V, 9V, 12V, 24V?
    On the input pins. Do you have this information?
  • It's a low DC voltage 24v that can supply 165ma. This gauge is not designed to run without a rough gauge controller.

  • Perfect and thanks again.
    I'm building a rough controller.
    Just confirming, the power pins are pins 1 and 3 (FIL), are these the correct input pins? Do I apply a low DC Voltage of 24V with 165ma?
  • The power is supplied to the 2 filaments pins 1 and 3 and the output is from pins 5 and 7. It's not a simple controller to build, good luck.
