When you need to measure extreme temperatures beyond the range of ordinary sensors, or when you need to measure temperatures in enclosed spaces or in liquids, a thermocouple is just what you're looking for. With one VINT port on your hub, you can interface a J, K, E or T type thermocouple, chosen in software and converted to degrees Celsius automatically (See the Connection & Compatibility tab for a list of VINT Hubs). If you have other thermocouple types, you can open the channel in VoltageInput mode and convert to Celsius manually using a formula; See the User Guide for more information.
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 Connection & Compatibility 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.
Isolated for Stability
This Phidget is electrically isolated, allowing you to measure electrically noisy solutions (for examplle, a tank of water that has an electric pump running inside it). If you don't need isolation and want more thermocouples per VINT port, have a look at the "Other Thermocouple Boards" tab.
