Abstract
A device and method for measuring temperature is disclosed. The device, for example, can include a thermocouple configured to generate a voltage indicative of a junction temperature; a memory device configured to store a unique device ID and to store data; a logic unit connected to the thermocouple and the memory device; an I/O interface connected to the logic unit, the I/O interface configured to communicate with a computer system; and an internal temperature sensor connected to the logic unit, the internal temperature sensor configured to determine a cold junction temperature.
Claims13
A device for measuring temperature, the device comprising:
- a thermocouple configured to generate a voltage indicative of a junction temperature;
- a memory device configured to store a unique device ID and to store data;
- a logic unit connected to the thermocouple and the memory device;
- an I/O interface connected to the logic unit, the I/O interface configured to communicate with a computer system;
- and
- an internal temperature sensor connected to the logic unit, the internal temperature sensor configured to determine a cold junction temperature;
- wherein the logic unit is configured to use the voltage generated by the thermocouple and the cold junction temperature to produce a digital indication of the hot junction temperature and further wherein each device for measuring temperature has stored within said memory device an electrically readable device ID which is unique to each measuring device.
A device for measuring temperature, the device comprising:
- a thermocouple configured to generate a voltage indicative of a temperature;
- a memory device configured to store a unique device ID and to store a temperature value;
- and
- a logic unit connected to the thermocouple and the memory device, the logic unit configured to receive at least an indication of the voltage generated by the thermocouple and to determine the temperature value that corresponds to the received voltage and further wherein each device for measuring has stored within said memory device an electrically readable device ID which is unique to each measuring device.
