|1048_0 - PhidgetTemperatureSensor 4-Input|
Connect up to four thermocouples to this board to measure the temperature of four different objects. Plugs directly into a USB port.
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 User Guide.
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).
If you want to use a thermocouple with a Subminiature (Flat Pin) connector, you can use the 3106 - Thermocouple Adapter
