hi guys,
we are preparing a project and we wish to get temperature measurement of evaporator. contrary to classic approach in terms of mesuring temperature (from pipe surface), we are considering to put thermocouples into the evap pipe by drilling it. we want this because we thought that measuring temperature of refrigerator inside the system will make us more correct without deviation. our main problem is pipe diameters and fins on the evap. inner pipe diameter is too small 7 mm and distance between two fins is 5 mm. is there anyone having an idea or comment on how to put thermocouples into pipe with this conditions?
