Product Description

These are the proper GM-style sensors for use with the MegaSquirt line of ECUs and come with the weatherproof connector and crimp pins.  Suitable for use as a coolant temperature or oil temperature sensor, and is occasionally used as an air temperature sensor in certain applications where a fast acting open element sensor may become damaged.

The threads are 3/8″ NPT pipe thread – note that isn’t an actual 3/8″ outer diameter, but a pipe thread size based on pipe inner diameter.

    :

    A very useful sensor to measure enough precise temperatures of fluids.
    I measured three key points for use. Temperatures are in celsius. Why measure? To have better feeling and wider scale.

    -24’c = 33k ohms
    24’c = 2.78k ohms
    100’c = 178 ohms

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?

  • If you are connecting this to a device that supports 3 point calibration (all MegaSquirt units do), use these numbers if your device does not have a standard GM temperature sensor calibration curve.
    • 7000 ohms at 48 degrees F
    • 1930 ohms at 87 degrees F
    • 560 ohms at 146 degrees F

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?

  • We currently buy the sensor and connector as a single item and do not stock the connector on its own.
