Read up to four thermocouples via USB with the 1048_0B Temperature Sensor 4-Input Boardto measure the temperature of four different objects.

Note: Due to parts and components going obsolete and becoming unavailable, the 1048_1B has moved to a new processor that is not supported under Phidget21. If you’re using our old libraries you must upgrade to Phidget22 before you can make use of this Phidget.

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.

  • Plastic shell enclosure
