Description

4 point multipoint thermocouple design. The C329 multipoint thermocouple is the ultimate in strength and reliability. Each measurement location has both positive (+) and negative (-) conductors of the thermocouple. The initial large cable is swaged down to achieve this. The space around thermocouples is filled with hard pack MgO insulation, as is the case with traditional Mineral Insulated thermocouple cables. Pyrosales custom design and manufacture multipoint thermocouples to suit customer requirements. They are reliable  measurement sensors and are available in types K, J, E, T and N.
