What size hole do I need to drill to install this sensor?

  • The hole should be tapped for 3/8″ NPT.  Your tap will come with instructions for the preferred drill size, which is likely to be 9/16″.

What is its resistance vs temperature curve?

I am using it with a device that requires a voltage vs temperature curve. What data do I enter?

  • This sensor outputs resistance, not voltage. You will need additional, external circuitry to convert its output into a voltage, and the voltage will depend on the design of the external circuit.

Can I buy the connector separately?

  • No, as this sensor includes an integrated 8.5ft flying lead harness to cut to length if required.

Where exactly should I install this on my engine?
