Temperature Sensor

Developed for use with our EFI and Ignition systems our thermocouple style temperature sensor is designed to measure the temperature at the cylinder head and give a much more accurate reading of engine operating temperature than a regular oil / water sensor who’s readings tends to lag behind actual engine temperatures. This means that the thermocouple has a much quicker response time and so provides a faster and more accurate data for warmup enrichment, fan control and over-temperature protection.

Designed to replace the regular coolant (CLT) sensor , it is compatible with both Speeduino and Megasquirt systems. The thermocouple is supplied with three point calibration data and a resistance lookup tables that can also be utilised by a variety of other ECU’s and electronics applications.

The thermocouple has a range of -55 through to 200 degrees Celsius and is designed to mount under the tin-wear screw adjacent to the spark plug. This location is optimised for the range of this sensor.

Supplied with a flying lead and unterminated plug, this sensor is easy to integrate into your wiring loom.

Note: The sensor can also optionally be ordered with a longer lead. Just ask.
