There are two basic types of electronic temperature sensors: thermocouples and resistance sensors (primarily RTDs and thermistors.) Thermocouples have much less mass in the sensor itself, and can be grounded - meaning the sensor actually touches the inside wall of its protective sheath, giving a much quicker transfer of heat energy - for a non-transmitting […]
