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.
Package contents:
- 1 x Phidgets board
- 1 x USB mini-B cable, 1.8 m
- 4 x M3 bolts
- 4 x M3 nuts
- 4 x Plastic spacers
Very long thermocouples are okay (even 100 m), 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 the Phidgets tutorial on Addressing EMI Issues.
