There are two common solutions to this problem used by industrial sensor 
manufactures: either provide cooling for the sensor via flowing water or 
air, or separate the electronics from the actual sensor apparatus.

If your sensor is in intimate contact with the pipe for a long enough 
period of time, no amount of insulation will prevent it from reaching the 
steady-state temperature of the pipe.  Good insulation will just make it 
take longer.

If you can take your measurements quickly, it may be possible to attach the 
sensor, take the reading, and remove it before you cook it.

My recommendation would be to separate the electronics from the sensor by 
wire and design it so that you can easily attach a new sensor.  This way, 
if you do cook the sensor, you are minimizing the exposure to the rest of 
the device.
