Specialty Thermocouple Designs

There are many different thermocouple configurations in addition to Temprel's standard design. Here are some specialty thermocouple designs that may help your selection:



Reduced Tip

The mechanical strength of the .125 inch diameter probe with the time response of the .062 inch. The thermocouple tip is swaged down for ¾ inch to achieve this design. This is available on all sheath materials and is commonly carried in Hastalloy (specify H for sheath material).



Venturi Tip

In some applications, the thermocouple reading can be affected by radiant energy from heat sources close to the desired gas stream reading.  This design provides a shield from these heat sources while providing for a flow path to measure the desired gas stream and protect the smaller tip.

3-prong standard plug

For applications requiring continuation of the circuit ground, we off a molded on 3-prong standard plug. The grounding wire is brazed to the third copper pin to ensure continuity of the connection. Specify S3 in the connector option of the part number.
