Benefits and Features

Junction is electrically isolated from the soil, thereby avoiding measurement errors due to differences in ground potential

Compatible with most Campbell Scientific data loggers

Technical Description

The 105SE consists ofa shielded, 24-AWG, type E thermocouple wire. Its junction is electrically isolated from the soil (or other media being measured). Electrical isolation avoids measurement errors due to differences in ground potential.

Type E thermocouples are comprised ofa chromel wire and a constantan wire joined at a measurement junction. A voltage potential is generated when the measurement end of the thermocouple is at a different temperature than the reference end of the thermocouple. The magnitude of the voltage potential is related to the temperature difference. Therefore, temperature can be determined by measuring the differences in potential created at the junction of the two wires.

Areference temperature measurement is required for thermocouple measurements. The temperature sensor built into many of our dataloggers' wiring panel typically provides this measurement.
