Hi Guys,
I have two temp probes on one pipe . lets call it probe 1 and probe 2
the distance between probes is approx 3-4 meteres away but the closest temp probe called probe 1closest to the heat exchnager reads less that the the probe 2 down stream by 2 deg, Intially probe 1 was a pt100 and probe 2 is a thermocouple type t, thinking different sensing types might cause this,I changed probe 1 to a thermocouple type t. the scales of both is 0-250. The are from the same brand Endress and Hauser. Probe 2 was also changed and had a 5 point calibration. Theoretically probe 1 should read higher temp than probe 2 but its actually not the case> Any ideas on what this could be?
