The sensor diameter should be approx. 1 mm smaller than the bore diameter of the

thermowell or the blind bore, respectively.

Gaps of more than 0.5 mm between thermowell and the sensor will have a negative eect on

the heat transfer, and they will result in unfavourable response behaviour of the thermometer.

Sensor lengths
