4x Thermocouple Phidget
With this Phidget, you can connect up to four thermocouples to a single VINT port, making it ideal for temperature testing and comparison (See the “Compatible Products” tab for a list of VINT Hubs). You can use a J, K, E or T type thermocouple; set the appropriate type in software and it will convert sensor data into degrees Celsius automatically. If you have other thermocouple types, you can open the channel in VoltageInput mode and convert to temperature manually according to your thermocouple’s datasheet.
Long Wires
One of the major advantages of using a thermocouple is the capability of using long wires. Thermocouples have been known to work with segments as long as 100m, while USB and other sensors suffer from voltage drops after 5 or 10m. You can find thermocouple extension wire on the Compatible Products tab. Please note that the longer you make your thermocouple wires, the more likely it is that you’ll experience noise and interference. For more information, see our document on Addressing Electromagnetic Interference.
