WebThe two common types of connector are ‘standard’ with round pins and ‘miniature’ with flat pins. This causes some confusion as ‘miniature’ connectors are more popular than ‘standard’ types. When choosing a thermocouple, consideration should be given to the thermocouple type, insulation and probe construction. WebThe most common thermocouples, types E, J, K, N and T change about 30 to 60 microvolts per degree C change in temperature. A data acquisition device that has a 10 V full scale range and 16-bit resolution can therefore only detect a change of 3 to 5 degrees C or larger. Thus amplification is usually required.
