Flow-Thru temperature sensors use either the Nanmac Right-Angle Ribbon Thermocouple or a Pt100 ohm RTD. The Right-Angle Ribbon Thermocouple utilizes a special ribbon element which eliminates conduction error due to shallow immersion in the flowing gas or liquid within the pipeline. Additionally, this ribbon design also provides response times in the low milliseconds.

All Pt100 RTD devices are of sanitary design as the sensor is separated from the material within the pipeline by a 0.015 inch thick stainless steel diaphragm. Thermocouples requiring sanitary design are also available by adding the diaphragm to the thermocouple.
