EGT Weld- In Sensor Installation Notes
When installing the Thermocouple probes into your headers please note the following:
• For accurate temperature readings the placement of the weldment should be as close
to the header flange as practical up to 100mm from the flange is acceptable.
• All weldments should be mounted in a position consistent on all pipes. It is very
important that they are all equidistant from the flange.
• The ideal depth for the thermocouple probes in installations other than turbocharged or
any supercharged nitromethane applications, is to have the probe located in the centre
of the pipe.
• The ideal depth for the thermocouple probes in turbocharged or supercharged
nitromethane fueled engines should be no more than 6mm into the pipe
EGT Weld- In Sensor Installation
1. Select the header tube in which you wish to mount the probe
2. Select the sensor location point on the pipe.
3. Once the position is located, drill a 5/16 inch diameter hole in the header tube
4. Remove the plastic protective tip from the thermocouple probe
5. Center the weld-in weldment around the hole and weld to the header pipe a full 360
degrees
6. Install the compression cap and ferrule on the welded base and bring up finger tight
7. Measure the distance from the exposed tip, up the hot leg of the sensor that's equal to
the height of the compression fitting plus the immersion depth that the sensor will extend
into the exhaust stream. Mark that length using a marker or pencil
8. Insert the thermocouple probe through the installed mounting hardware until the mark
touches the top of the cap and tighten the compression nut using a 9/16 inch spanner.
Make sure sensor transition and spring is at a 90 degree angle to the exhaust pipe, if
room permits. This will position the sensor tip correctly in the exhaust stream
