The TMP1101 allows you to measure extreme temperatures with up to 4
thermocouples. It is great for measuring temperatures in enclosed spaces or in
liquids. This Phidget connects to your computer through a VINT Hub. 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.
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.
