Thermocouples are widely used to measure extreme temperatures impossible to measure with other types of sensors.
J, K, E and T thermocouples are directly supported in the library and return the measured temperature in °C.
It is possible to interface other thermocouple types by converting the measured potential returned by the Temperature Sensor into Celsius using the appropriate tables; the formula and links to the tables are described in the 1048 Product Manual.

- Supports up to four J, K, E and T-type thermocouples
- Outputs temperature in degrees Celsius
- Uses terminal blocks to interface to inexpensive thermocouples with stripped leads
- Connects directly to a computer’s USB port
Very long thermocouples are okay (even 100m), but if there is measurement stability issues or USB resets, ferrite beads can be added to the thermocouple wire close to the Phidget Temperature Sensor. See our tutorial on Addressing EMI Issues.
We offer a choice of thermocouples with different maximum temperature values:
- 3107 - Bead Probe K-Type Thermocouple (-50 to +200°C).
- 3108 - Immersion Probe K-Type Thermocouple (-50 to +700°C).
- 3109 - Bead Probe K-Type Thermocouple (-50 to +450°C).
- 3110 - Bead Probe K-Type Thermocouple (-50 to +785°C).
- 3015 - Omega K-Type Thermocouple.
If you want to use a thermocouple with a Subminiature (Flat Pin) connector, you can use the 3106 - Thermocouple Adapter
Comes packaged with:
- A 3018 - Mini-USB Cable 180cm
