Specialty Designs & Services

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.

Calibration Services

We can calibrate any thermocouple or spools of bulk wire with NIST secondary standards and tractability. Should you require matched sets of thermocouples, please specify the type, quantity and desired operation range. We will calibrate the thermocouples at that temperature and pair off the matching units. This is an excellent method of selecting pairs for measuring the inlet and outlet temperatures of heat exchangers.

Repair or Replace Service

Temprel, Inc. can examine your old and/or used thermocouples and we will quote you a price to provide the necessary repairs to your sensor.
We will also quote you the price for a comparable replacement if it is beyond repair.
No matter which way you choose to go, you can still take advantage of our one year warranty. Please see our warranty page for details.
